云南高原楚雄市近年来城市气候特征研究

基于楚雄市城区中心气象站和周围9个加密气象站点及南华2010~2014年气象观测资料,利用Excel制作图表等对楚雄市近年来城市气候变化特征及成因进行了分析与研究,得到楚雄市城市气候变化规律,利用灰色关联分析方法对影响楚雄城市气候的自然和人文因子进行了分析。研究结果表明:近年来热岛强度呈先下降后上升波动趋势,热岛强度最大是在2010年,最小是在2013年,3月份热岛强度最强,8月份最弱。近5年间的降水量波动较大,降水量最多在2014年,最少在2012年,城市雨岛效应比较明显,降雨干湿季分明,城市雨岛强度雨季大于干季。城市相对湿度比郊区少,城市干岛效应明显,楚雄市城市干岛强度雨季大于干季。影响楚雄市城市气候的因子既有人文因子也有自然因子,且人文因子的影响大于自然因子。     

西北地区城市化对城市气候环境的影响

以西北地区五个省会城市所在的地区为研究区域,分析了近50年西北地区城市气候的变化趋势,考察了城市发展对气候的影响,发现西北地区大城市存在显著的热岛效应、雨岛效应、干岛效应和暗岛效应。在此基础上建立了城市发展与城市气候变化之间的回归模型,证明西北地区城市发展对气候的影响不完全符合库次涅茨曲线特征。     

近50年来兰州城市气候变化的R/S分析

运用R／S方法、城效对比法，对1951－1999年兰州市城市气候的温度、水汽压、相对湿度和日照百分率等指标的冬（1月）、夏（7月）及年平均值进行了计算分析，各项指标的Hurst指数H均大于0.5，说明它们存在明显的赫斯特现象，反映了兰州市近50年来气候变化存在趋势性成分，即持续性的城市化气候效应。至于各项指标的Hurst指数在冬、夏及年平均值间有差异，分析证明这是兰州城市化气候效应强度的季节差异所造成。     

杭州城市气候

随着生产的发展,城市规模不断扩大,城市作为一种特殊的下垫面对气候产生明显的影响。无论城市建设还是环境保护等方面都需要城市气候研究成果。杭州是我国著名的风景游览城市和疗养胜地,因此,研究杭州城市气候更具有特殊意义。现根据有关气     

基于FSDAF模型的干旱区典型绿洲城市夏季地表热岛效应时空演变研究

全球城市化进程加快引起的干旱区绿洲城市热岛效应变化及其生态环境问题已成为当前国内外城市气候、环境和生态等领域的研究热点之一.基于遥感热红外通道反演的地表温度(Land surface temperature,LST)是开展城市地表热岛(Surface urban heat island,SUHI)效应监测研究的关键参数...     

昆明城市发展对室内外平均气温影响的研究

利用受城市扩大影响的昆明气象站室内外气温资料和未受城市影响的太华山气象站气温资料，以及城市建成区面积和城市人口资料，分析了昆明城市发展对室内外平均气温影响程度，由于城市面积扩大导致昆明的室内外气温均升高，城市增温效应在1-4月较大，5-12月较小；城市增温效应的主要影响因子在上半年是城市人口增加，而在下半年则主要是城市建成区面积的扩大，另外，城市增温效应与城市建成区面积、城市人口均有较好地相关关系，城市建成区面积增加对平均气温的影响较大；而城市人口增加对平均室内气温的影响较大。     

应用卫星图像的热岛效应,研究福州市区用地动态变化

城市热岛效应是城市气候最明显的特征。福州是较早沿海开放城市之一，随着城市化的迅速进展，其规模越来越大，市区成为人口稠密、建筑物密集及工业高度集中的地方，市区中工业生产、交通运输、人群呼吸及家庭生活中排出大量热气、尘埃和废气（尘埃能吸收太阳辐射，也使其自身增温），形成了市区温度高于郊区的气候现象。热红外图像上能反映出地物温度，便为研究城市热岛效应提供了依据。由于受卫星资料来源限制，作者仅应用福州市区1988年4月9日和1992年1月5日两个不同时过境的TM数据磁带，结合气象资料，探讨利用福州市区热岛效应的气候…     

基于财富500强中国企业网络的城市网络空间联系特征

基于2015年世界财富500强中的102家中国企业数据,根据企业组织特征构建了反映企业—城市间关联的折衷网络模型,借助网络分析等多种方法分析了中国地级城市间和典型城市群之间的网络联系。研究发现：① 城市网络总体连通性较差、向心集中性强,发育不够完备;城市网络连接具有明显的行政中心指向、沿海指向和资源指向;网络节点城市对外经济依赖度高,网络结构扁平特征明显。城市群网络存在权力分散、地位分化和外部联系依赖特征。② 城市网络中省域、城市群和俱乐部边界效应明显,区域内外的中心城市规模和数量对省域行政区经济、城市群经济和俱乐部经济的发展产生影响。③ 城市在多尺度网络中的功能分化明显,大城市和区域型中心城市比中小城市拥有更加完备和均衡的功能体系。沿海三大城市群的辐射带动作用明显,其他城市群的优势功能有待突出。④ 城市（群）跨尺度区域功能互动效应显著,城市（群）的自我经济集聚能力与城市（群）的对外辐射带动功能之间存在密切的正向关系。研究为城市网络模型拓展及理解中国城市网络空间联系特征提供了支撑。     

商品住宅价格空间溢出效应测度及其影响因素分析——来自长三角地区的证据

商品房价格的空间溢出效应是当前学界探讨的重要议题,但鲜有研究基于区域视角测度并对比不同商品房价格空间溢出效应的差异。本文以长三角地区为例,基于GIS的空间计量模型尝试测度商品房价格的空间溢出效应,并进一步对比分析三种商品住宅（新住宅、二手住宅和租赁住宅）价格的空间溢出效应及其影响因素。结果表明（：1）上海、杭州和南京三个城市的商品住宅价格明显高于其他城市,说明其价格与城市的经济（行政）等级密不可分（;2）三种住宅价格均表现为由上海向内陆区域依次降低的空间规律,具有明显的空间等级性（;3）新住宅、二手住宅和租赁住宅价格的空间溢出效应依次减弱,但新住宅和二手住宅价格的溢出效应差别不大（;4）上海、苏州、南通和嘉兴四个城市处于高房价集聚区,该区域商品房价格与周边城市的商品住宅价格存在显著的空间溢出关系（;5）经济基础、消费需求和社会资源对三种商品住宅价格的空间溢出均具有显著的促进作用。     

“列车流”视角下西北地区城市网络结构演变研究

基于西北地区2014年、2016年、2018年、2020年铁路客运班列数据,运用列车频次优势度、复杂网络理论及社区结构识别等方法分析西北地区城市网络结构的演变。结果表明：（1）西北地区铁路建设加强了城市间的联系,社区数量减少,已形成分别以西安、兰州、乌鲁木齐为核心城市的稳定的多中心结构。（2）西北地区高速铁路建设对城市中心度及中介度的影响较小,对列车频次优势度的影响比较明显,西北地区高铁建设仍需注重“量”的积累。（3）西北地区各城市列车频次优势度及中心度呈现出明显的“沿途效应”。（4）基于普速铁路联系强度划分的社区空间分布与城市群分布有较强的一致性,但也存在差异,在考虑高速铁路列车频次的影响下,这种一致性不再明显。

Deserts and Aeolian Desertification in China: Book review and some thoughts

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.

THE MOST PERFECT EXAMPLE OF AN ALIEN ECOLOGY EVER CONSTRUCTED

Much science-fiction literature is based upon the creation and exploration of alternative environments. Stanley G. Weinbaum's short story, “Parasite Planet,”introduces an unusual environment that may be wrong in the light of recent evidence on Venus but still stimulates the geographical imagination.     

Metals and models: Diagenic modelling in freshwater lacustrine sediments

This review aims to distill and synthesize the existing information on the use of models to describe and predict the distribution and movement of metals in lacustrine sediments. As such it examines the causes of metal diagenesis, the origin and form of the equations that govern these phenomena, and the predictability or measurability of the parameters that appear in the models. The paper concludes by highlighting some seminal results from modelling studies, including the determination of the factors controlling the formation of surficial Mn-Fe-enriched zone or layers, the substantial contribution possible from metal reduction to organic matter regeneration, the calculation of mixing-corrected metal input histories to lakes, and the prediction of growth rates and morphologies for both deep-sea and lacustrine ferromanganese nodules.     

Guidelines to Authors

正1.Aims and scope Sciences in Cold and Arid Regions(SCAR)is a bimonthly journal that publishes in English the latest research achievements in processes and the patterns of the Earth surface system in cold and arid regions.Researches in cold regions emphasize particularly on the cold-region-characterized physical,chemical and biological processes and their interactions,and on the response of cryosphere to global change and human activities as well as their effects on environment and the acclimatizable strategies;focus on the objects of glacier,snow,river,lake,sea ice,permafrost and seasonal frozen ground,and periglacial geomorphology,etc.;and think much of cold regions
