Residents’ satisfaction with public services in mountainous areas: An empirical study of southwestern Sichuan Province,China

Enhancing the efficiency of public services is essential to residents in mountainous areas. It is also important to promote sustainable development of these regions. Analysing residents’ satisfaction with public services in mountainous areas can help in evaluating outcomes of fiscal investment and identifying potential coping approaches for improving public service efficiencies. The residents’ satisfaction with public services and the factors that influence such satisfaction were examined in this study. A study of 12 towns located in the southwestern Sichuan Province was performed using an entropy-weighted analytic hierarchy process (EWAHP), the technique for order preference by similarity to ideal solution (TOPSIS) and Tobit regression methods. The results indicate that: 1) the spatial distribution of satisfaction with public services is non-uniform, and the spatial distribution structure varies for different types of public services. 2) Residents’ satisfaction with public services is influenced by both objective and subjective factors. Population density, economic distance, social and cultural divisions and elevation are the major objective factors, whereas bounded rationality, the hierarchy of needs and service expectations are the main subjective factors. The most effective strategies for enhancing residents’ satisfaction with public services are likely to be clustering the population, choosing supply centres with different public services, regulating the cultural division in ethnic minority towns, selecting supply priorities in accordance with residents’ needs, implementing targeted intervention policies and establishing ‘bottom-up’ and ‘top-down’ integrated decision-making mechanisms.     

山地城市公交系统服务在老年人群体中分配公平性评价

公交系统作为一种面向公众全体尤其是弱势群体的公共服务设施,其公平性对于促进宜居城市与公交都市建设具有较大的现实意义。本研究考虑山地城市地形变化的影响,提出了一类测度公交站点实际服务范围的新方法来修正公交服务供给公平性评价模型,并以贵阳市为例,对贵阳市公交系统服务供给在老年群体中分配的公平性进行分析。研究结果表明： ① 山地城市地形影响下的公交站点实际服务范围将降低,公交供给服务水平明显下降;② “常规+BRT（Bus Rapid Transit快速公交）”公交系统服务供给在老年人群体中分配公平性程度处于差距悬殊等级,且分配呈现出两极分化趋势;“常规+BRT”公交系统服务供给在老年人群体中空间配置失衡较为显著,城市核心区老年群体较为集聚,然而享有的人均“常规+BRT”公交系统服务供给低于整体水平;③ 若增加轨道1号线,“常规+BRT”公交系统服务供给在老年人群体中分配呈现出的两极分化趋势在一定程度上得到了缓解;“常规+BRT”公交系统服务供给在老年人群体中的空间配置失衡得到一定改善。研究结果能为山地城市交通规划部门合理布局公交系统服务供给设施提供理论参考。结合山地城市地形变化特点,本研究针对公交系统服务供给存在的公平性问题,提出了相应的优化建议。     

Measurement of self-development capacity in the contiguous destitute mountainous areas,China

Affected by the mountainous location and ecological vulnerability, the incidence of poverty in contiguous destitute mountainous areas is higher than that in other regions of China. Regional selfdevelopment capacity is an internal driving force for poverty reduction in contiguous destitute mountainous areas. This study selects 17 indicators from the four dimensions: industrial capacity, market capacity, spatial capacity and soft power to measure the overall self-development capacity of 658 counties in 14 different mountain areas in China. The results show that self-development capacity is at a low level and the development of the different regions is unbalanced. The self-development capacity is low in the southwest and high in the east and "low in the middle, high around" in each study region. It has achieved a certain degree of improvement in 2011, 2013 and 2015. From the perspective of the four dimensions, industrial capacity is the constraint on the promotion of self-development capacity. Based on this, we should develop green industries in line with local realities and achieve industrial poverty eradication, but the expansion of space capacity should take into account the resources and environmental carrying capacity in these areas and should not be blindly expanded. Local leaders should be made to improve the local education level and public service level, improve social infrastructure, develop reserve strength for the future, and enhance future development potential.     

空间同位模式支持下城市服务业关联发现及特征分析

空间同位模式分析是数据挖掘中一种常见的方法,可有效挖掘城市设施在空间位置上的关联特征,进而发现城市设施的分布规律。本文基于POI数据同位模式挖掘用来获取城市服务业空间关联结构：首先,通过邻近实例获取、同位候选模式存储与筛选,得到城市服务业二阶同位模式;然后,据此构造产业空间关联图,得到产业间的关联结构;最后,分别构造了产业空间关联图密度和产业空间关联显著指数,用来衡量城市服务业空间关联的紧密程度和整体关联的显著程度。本文选取成都、兰州、郑州、沈阳、上海与深圳为试验区,实验结果表明：不同城市服务业的空间关联结构存在共性与特殊性,整体上,餐饮、购物等与居民日常生活相关的服务业易与其他服务业产生空间强相关,这几类服务业内部空间集聚明显;成都与沈阳的服务业整体表现空间关联度高且紧密,兰州其次,上海与深圳的服务业则整体表现空间关联较弱,郑州的服务业空间关联较紧密但强度较低。     

武陵山片区扶贫重点县农村基本公共服务均衡化差异分析

实施农村基本公共服务均衡化是当前农村扶贫开发的重要思路和方向之一.本文选取武陵山连片特困区67个扶贫重点县,构建贫困地区农村基本公共服务评价指标体系,采用基于博弈论的主客观权重法,评价研究片区农村基本公共服务综合发展水平,并利用基尼系数与最小方差法从片区-省-县多角度测度研究片区农村基本公共服务维度指标的发展差异,揭示贫困县农村基本公共服务的空间差异特点,为农村基本公共服务资源的均衡化配置决策提供参考.结果表明:(1)片区层面上的农村基本公共服务整体质量不高,呈现出明显的西北高,东南低的态势,片区所辖湖北省和重庆市的整体发展水平较高;(2)片区整体农村公共安全服务维度发展不均衡,县域间存在较大差异,其它维度发展相对较好;(3)发展差异类型上,大多数县市是五维度主导型,麻阳县受双维度支配,德江县和石阡县是七维度联合型.     

城市功能区视角下基于POI数据的公共厕所空间布局合理性研究

公共厕所作为最典型的公共设施,反映出城市的文明程度和管理服务水平,是打造城市文明形象的重要窗口。当前的研究主要集中在公共厕所的可达性和覆盖范围,把公共厕所当做空间上的点无差别对待,忽略了不同功能区公共厕所空间分布所异质性的问题。如何建立全面精准的公共厕所空间评价体系,分析不同区域公共厕所的综合服务能力在当前研究中明显不足,不利于公共厕所的配置规划和基本公共服务均等化的推进。多源数据的涌现为城市公共设施的研究提供了新视角,为此本文提出一个城市功能区视角下基于POI大数据的公共厕所空间布局合理性评价方法。利用词频-逆文本频率（Term Frequency-inverse Document Frequency,TF-IDF）信息加权技术,结合兴趣点（Point of Interest, POI）频率密度识别城市功能区,融合OpenStreetMap（OSM）路网密度数据和WorldPop人口数据设立人口出行活力指数,对城市功能区内的公共厕所服务进行评价;最后计算人口和空间覆盖率以及空间不平衡指数,判别街镇间的差别与街镇内公共厕所布局的合理性。该方法以多源数据为基础,定量分析不同功能区内公共厕所配置的合理性,并探讨公共厕所空间配置的差异化因素。以国内城市化程度最高之一的上海市为例进行计算,研究发现:① 不同的城市功能区内厕所的配置数量不同,商服功能区的规划数量最多,商服功能区中公共厕所配置的合格度也最高,此外,“工业-商服”、“绿地-商服”等商服相关的联合功能区的合格度也处于较高水平,这是由于大量商业服务机构均对外提供公共厕所服务,提升了该地区的公共厕所的服务能力;② 公共功能区内的合格度最低,仅有10.27%,与该类型附属公共厕所设施的开放程度相关;③ 上海市各街镇公共厕所的合格度整体较好,平均空间覆盖率达到67.31%,平均人口覆盖率达到70.72%;街镇内公共厕所服务和出行活力分布之间的不平衡指数从0~0.76不等,其中不平衡指数小于0.4的共有147个,占比69.34%,表明这些街镇内公共厕所空间配置比较合理。公共厕所配置合理性从上海市区向西南、东南、崇明岛有明显的递减,而向西北地区则没有明显的衰减,呈现出连片的较好的服务能力。结果表明,这种方法充分考虑了公共厕所所属功能区和人口出行活力异质性的问题,空间分析上更加精准,可以为城市公共设施规划提供参考建议。     

Spatial Differentiation and Influencing Mechanism of Medical Care Accessibility in Beijing: A Migrant Equality Perspective

Spatial equality of access to basic public services, especially medical care services which are directly related to life safety, is the first step to achieve the goal of equalization of basic public services for all the people proposed by central government of China. Using the spatial analysis and the statistical analysis, this study evaluates the spatial differentiation of medical care facilities accessibility by constructing STT (Shortest Travel-Time) and SAI (Spatial Accessibility Index). And then this study explores the neighborhood effects on the medical care facilities accessibility in Beijing, with a particular focus on the effect of neighborhood migrant proportion by constructing spatial dependent regression model. The spatial accessibility analysis of medical care facilities show that the spatial distribution of medical care facilities was basically consistent with administrative regions but not with population demands. Bivariate LISA cluster maps identify that suburban areas are the overlapped clusters of high percent of migrants and limited medical care services. This is associated with the public service allocation rule in China, which stresses equality within urban areas and within rural areas but overlooks equality between urban areas and rural areas; and stresses local resident demands but overlooks migrant demands. To estimate the effects on medical care accessibility of neighborhood migrant proportion, spatial dependence models are applied due to spatial dependence of accessibility of medical care facilities. The regression results show that neighborhoods with high percent of migrants, even conditioning on neighborhood SES, are related to limited spatial accessibility of medical care services. Besides neighborhood characteristics, another important factor influencing spatial accessibility of medical care services is the process of spatial spillover effects. This indicates that the attenuate accessibility of medical care services for migrants is not only because of their own constraints but also because of their proximity to other disadvantaged neighborhoods. Therefore, it is urgently needed to increase the medical facilities in the suburban areas, to take into account migrants’ demands and to reduce residential segregation between local residents and migrants for local governments to achieve the goal of equalization of medical care service.     

融合地图数据的山地城市医疗设施服务覆盖评估方法研究

随着我国社会经济的不断发展,居民对医疗的需求不断增加,分析评估城市医疗设施服务范围,对解决医疗供需矛盾,提升城市健康水平具有重要意义。目前国内医疗设施服务覆盖评估,多忽视交通网络与人群分布因素,致使城市医疗服务存在不少覆盖盲区。山地城市复杂地形环境影响居民出行能力与出行方式,增大医疗设施服务覆盖的难度,传统方法难以对其准确评估。本文在分析比对现有医疗可达性研究方法优劣势的基础上,以重庆市主城区为实验区,试图针对性地采用优化两步移动搜寻法,并根据网络地图数据、官方统计数据,基于GIS平台建立医疗设施可达性分析模型,从市域、片区与社区3个层级科学评估医疗设施服务覆盖范围与各街镇医疗可达性。结果表明,改进后的方法更能处理海量医疗数据,准确模拟医疗服务范围,并输出全层级医疗设施服务覆盖评估结果,更适用于交通复杂的山地地区与多层级医疗设施服务覆盖评估。综合评估显示,重庆市主城区医疗设施服务存在大型综合医院空间分布不均、基层医疗设施内部覆盖不全的问题,并且医疗覆盖度较好的街镇仅占总数的33.1%。据此,建议老城区集聚的优质大型医疗资源向新城地区共享的同时,按照地理区位与技术能力划分、组建层级完备的医疗片区,补齐老城区基层医疗服务的短板,以期完善重庆主城区医疗设施配置。     

Agricultural opportunity costs assessment based on planting suitability: a case study in a mountain county in southwest China

Payment for ecosystem services (PES) has become an increasingly popular means of ecosystem conservation. Opportunity cost is an important factor to increase the investment efficiency of PES projects. However, the distribution of opportunity cost is usually unclear in mountainous regions due to the obvious environment changes. In this study, we developed a framework to assess the distribution of agricultural opportunity costs in mountainous regions and applied this method to Baoxing County, a typical mountainous county in Sichuan Province of southwest China. Planting suitability of 17 crops was assessed based on agricultural statistics and natural conditions data within a GIS environment. Agricultural opportunity cost was quantified with a weighted summation of farmers’ willingness to cultivate and each crop’s opportunity cost. Finally, specific agricultural opportunity cost was obtained according to the spatial areas of the protection programs and land use status. The results showed that agricultural opportunity costs of PES in Baoxing County were estimated to be more than $30 million, with a mean of 400.85 $/ha. Agricultural opportunity costs in mountainous regions displayed some obvious spatial variation and areas with lower agricultural opportunity costs could be selected as priority areas for PES. Our findings revealed that the planting suitability evaluation can make agricultural opportunity costs mapping more reasonable. It will be helpful for the PES programs implementation in mountainous regions.

Dynamic Analysis of Supply and Demand Coupling of Ecosystem Services in Loess Hilly Region: A Case Study of Lanzhou,China

The relationship between the supply and demand for ecosystem services(ESs) is a key issue for the rational allocation of natural resources and optimisation of sustainable development capacity. This paper investigateed the dynamic evolution features of supply and demand of four ESs in Lanzhou of China, namely, water supply, food supply, carbon fixation and soil retention services. The crosssectional data of 2005 and 2017 were used for calculating ESs value and its supply and demand through ArcGIS software, InVEST model, elastic coefficient model and coupling coordination model. Results showed that: 1) from 2005 to 2017, the supply of water supply services increased, the demand of soil retention services decreased, and the supply and demand of food supply and carbon fixation services increased. The high-value areas of service supply were mainly distributed in the rocky mountain areas in the southeast and northwest with high vegetation coverage, while the high-value areas of demand were mainly distributed in the urban areas and surrounding areas with high population density. 2) There were five different types of coupling relations. Water supply service was dominated by a negative coupling type D, which means that the decrease in demand for ESs has had a positive response on the supply of ESs. Negative coupling type C was the main type of food supply and carbon fixation services, which means that the increase in demand for ESs has had a negative response on the supply of ESs. All three services were supplemented by a positive coupling type A, which means that the increase in demand for ESs has had a positive response on the supply of ESs. Soil retention service generally exhibits a positive coupling type B, which means that the decrease in demand for ESs has had a negative response on the supply of ESs. 3) Over the past12 yr, the coordination degree of supply and demand of water supply, food supply and soil retention services decreased, and the coordination degree of carbon fixation service increased. Various types of ES had a low degree of coupling and coordination, showing different characteristics of temporal and spatial evolution. The areas with imbalanced ESs supply and demand were mainly distributed in urban areas dominated by construction land. The research results are valuable to the optimisation of urban and rural ecological environments and the sustainable development of territory space under the framework of ecological civilisation, including similar ecologically vulnerable areas in other developing countries.

基于累计机会可达性的北京城市公共服务设施复合功能识别

城市时空大数据技术的快速发展和应用,为城市功能区识别提供了新的数据基础和技术手段,但专门关于城市公共服务设施复合功能的研究还相对较少。基于北京市9大类公共服务设施的空间点数据,综合考虑不同类型公共服务设施等级和品质特征,采用累计机会方法对1 km×1 km格网尺度的北京城市公共服务设施可达性进行了综合评价,在此基础上重点分析了北京城市公共服务设施复合功能特征与影响因素。研究表明：① 北京城市公共服务设施累计机会空间分布存在明显的中心集聚特征,但不同类型公共服务设施的空间分布模式和覆盖范围却有所区别;② 北京城市公共服务设施功能区可以划分为单一功能、单一化的复合功能、2种复合功能、3种复合功能和均衡化的复合功能等5大类型;③ 人口密度、距市中心距离、土地价格和经营性为主设施的累计机会可达性是影响北京城市公共服务设施复合功能的重要因素。研究结论对进一步细化城市功能区研究和促进北京城市公共服务设施空间结构优化具有科学启示作用。     

基于WSRF的网格空间服务及其管理

网格技术与空间信息技术的结合,产生了空间信息网格。空间信息网格能够汇集各种空间信息资源,进行一体化管理,支持资源共享,提供"按需服务"的能力。"按需服务"要求能根据用户的要求,提供多样性服务,即能自动发现所有满足用户需求的空间信息资源或其组合,并评估各个资源或其组合,按一定目的选择资源,提供服务。但是由于网格的动态性,使得使用者较难得到现势性很好的空间信息资源的信息,直接影响了空间信息网格"按需服务"的能力。将传统的空间信息服务技术直接融入网格不能解决这一问题。为了解决该问题,提高"按需服务"的可靠性,本文根据支持资源状态和服务分离的网格框架W SRF,提出了W SRF设计网格空间服务及其管理的方案。即在空间信息资源节点,除了将信息资源以标准服务的方式提供使用,还以W SRF的方式组织资源的状态并提供访问和订阅;网格中央节点收集、维护和管理各子节点的服务和资源状态信息,提供信息访问接口以支持"按需服务"所必需的资源选择。最后按照该方案实现了一个简单的空间数据网格。     

Changes in demand and supply of ecosystem services under scenarios of future land use in Vorarlberg,Austria

Ecosystem services(ES) are highly impacted by human-induced land-use change.Progressive urbanization and agricultural land abandonment in Western Europe necessitate assessments of future land-change impacts on ES to ensure sustainable service management. The present study aims at evaluating future demand and supply of three key services(flood protection, nearby recreation and biodiversity) in the mountainous region of Vorarlberg, Austria. We mapped the ES for the referenced time step 2016 and two scenarios for 2050,assuming the continuation of current land-change trends and pressure on landscape development.Results for the referenced landscape in 2016 show the highest ES supply for intermediate levels, while ES supply was low in the lowlands and valley bottoms and in high-elevation areas. We found a high positive correlation of ES with the distribution of forested areas. In contrast, service demand was highest in lowelevation areas and decreased with increasing elevation. This indicates that densely settled and intensively used agricultural areas currently suffer from ES undersupply. The projected future development of land use showed an increase in both supply and demand of the selected ES. The overall service supply increased more than the respective demand due to some reforestation of open land. As forests were found to be important synergistic areas for overall service provision, we expect decreasing demand on related services. Locally, demand was found to exceed the supply of ES, especially in the densely populated Rhine valley-requiring further policy interventions. Such ES-related information may contribute to regional policy making and ensure the long-term provision of ESs for future generations.

City Networks of Online Commodity Services in China: Empirical Analysis of Tmall Clothing and Electronic Retailers

City networks have been a critical topic in the fields of urban geography and regional economics. Numerous studies have explored city networks, focusing mainly on infrastructure and industrial networks. Unlike traditional urban network of which the major measuring indexes are population sizes and entity industries, online commodity service networks could reflect well the influencing of emerging economies, especially the Internet economy, on city networks. This study analyzes and reveals structural features of China’s city networks through online commodity services, providing the internet economic approach on city networks. Results indicate that the core cities of online commodity service networks are mainly concentrated in eastern coastal areas. In addition, spatial polarization and layer structure of network connections are obvious, descending from the centers in eastern China to peripheral cities in central and western China. Online commodity services of different cities show apparent differences and uncertainties in terms of specialization rates of international connection, which presents a tendency toward diversification. Online commodity service networks are not only associated with goods production, supply, and consumption in physical space but also reflect virtual information, capital, and technology flows, thus providing a new empirical approach for understanding city networks in information and internet economic age.     

The inequality of educational resources and its countermeasures for rural revitalization in southwest China

Equal access to education has long been a global concern and is important for rural revitalization strategy in the new era. However, little is known about the regional differences of educational resources in China, especially southwest China, where the spatial heterogeneity of human and physical geography is extremely significant. Using a dataset of primary and secondary schools of southwest China at county level in 2015, this study builds an index system to comprehensively measure the supply of educational resources, investigates the spatial pattern of educational resources via exploratory spatial data analysis(ESDA), and explores its influence factors through spatial econometrics. Results indicated that the supply level of educational resources in southwest China was relatively low; the high-high clusters of the supply of educational resources were mainly located in Sichuan Basin and the east of Western Sichuan Plateau, while the concentrated poverty-stricken areas of Guizhou and the border areas of Yunnan-SichuanGuizhou, especially Wumeng mountain area, were characterized by the low-low clusters. Furthermore, this study suggested that altitude, population density, local government revenue and rural residents' income were positively correlated with the supply of educational resources, while the negative influenceswere exerted by proportion of ethnic minority population and urbanization rate. And there were differences in the specific objects of actions of each factor. Ultimately, we proposed that village relocation and combination, as well as sustainable urbanization and regional development were practical paths to optimize the supply of educational resources in rural areas, thus promoting the modernization of agriculture and countryside.
