新时代的国土空间规划体系重建与制度环境改革

在全面推进生态文明建设背景下,急需建立适合中国国情的国土空间开发保护制度和国土空间规划体系,这是新时期建立空间治理体系的重要任务。在国务院新一轮的机构改革背景下,空间类规划的编制职能向自然资源部集中,急需探索和建立全国国土空间规划体系的总体框架和制度环境改革的推进路径。研究表明：国家国土空间规划体系的重建取决于三个方面,一是依赖于部门的职能整合,二是国土空间规划体系的整合与重构,三是依赖于制度环境改革。因此,在机构改革逐步完成的形势下,需要从国土空间规划体系重建与制度环境改革两个路径着手,从国家、省域、市县等层面阐述了中国国土空间规划体系的重建思路,构建五级四类、上下衔接、分级管理的国土空间规划体系。从确定国土空间开发保护制度、专业人才培养、规划资质管理、推进立法等几个方面推进制度环境改革。最后从推进国土空间规划立法、审批程序前置和推进相关法律法规修改完善等方面提出具体举措,以确立国土空间规划的法定地位与统领作用。结合新时期国土空间规划编制,提出了尽快出台国土空间规划编制办法和技术规程、重新调整中国国土空间规划编制的时序安排、加强技术队伍建设等若干建议。     

撤县(市)设区对城市空间扩展的影响机理——以杭州市为例

城镇化的持续推进对城市空间扩展产生了新的需求,撤县（市）设区是中国城市市辖区实现扩容提质的主要手段之一。以杭州为例,定量测度撤县（市）设区后杭州城区空间扩展的时空特征及其各方面的影响,并探讨了这一区划调整对城市空间扩展影响的作用机理。研究发现：通过撤县（市）设区,杭州城区的建设用地东扩趋势明显,萧山和余杭两区的建设用地新增面积和扩展速度均高于平均水平,且两地建设用地空间存在多中心集聚特征,成为新一轮的杭州建设用地扩展高密度区,城市功能不断凸显。总体来看,撤县（市）设区对城市空间的影响是间接的,具有一定的滞后性,通过引导城市空间扩展的主要方向,实现中心城市人口和产业向新设市辖区的转移和集聚,提供城市空间扩展的载体。撤县（市）设区后需要通过后续的城市规划修编、土地性质和权限调整、生产要素集聚与空间重组等路径,对城市空间扩张与空间演变产生直接影响。

A New Ootype of Dinosaur Egg (Faveoloolithidae: Duovallumoolithus shangdanensis oogen. et oosp. nov.) from the Late Cretaceous in the Shangdan Basin,Shaanxi Province,China

A new ootype collected from the Upper Cretaceous Lijiacun Formation in the Shangdan Basin, Shaanxi Province is described in this paper. Based on general external shape, size, eggshell thickness and honeycomb‐like eggshell microstructure, eggs are referable to the oofamily Faveoloolithidae. Compared with other members of Faveoloolithidae, specimens described in this paper show special characteristics: adjacent pores are usually separated by two eggshell units between which often develop interspaces; columnar eggshell units are relatively closely arranged in radial view. According to these characteristics, we erect a new oogenus and a new oospecies: Duovallumoolithus shangdanensis oogen. et oosp. nov. The new discovery expands the diversity of Faveoloolithidae.     

典型农区农用地承包经营权流转价格及对策研究(英文)

河南既是农业大省又是中国重要的粮食主产区,农用地流转顺畅及适度规模经营对区域经济发展和国家粮食安全产生重要影响。借助于土地使用权评估的基本方法,并使用土地承包经营权的权属特性进行修正,构建了土地承包经营权流转价格模型,并对典型区域沁阳市西万村进行了实证分析。结果表明,土地承包经营权流转价格应该包括经济价格、社会价格和修正价格。价格模型的应用,应甄别理论价格和实际流转费用的区分,农用地流转后经营项目没有转变,流转价格为经济价格和社会保障价格是总和。农用地流转后经营项目发生转变,比如耕地改种经济作物,流转价格则是经济价格、社会价格与修正价格三者的总和。收益分配格局存在复杂性,流转收益应在流出方、流入方、管理者和所有者之间合理、公平分配。政府应建立合理有序的农用地承包经营权流转市场,并以农用地流转市场为载体,构建农用地流转价格体系。     

Spatial structure and land use control in Extended Metropolitan Region of Zhujiang River Delta,China

The Zhujiang (Pearl) River Delta is one of the most developed Extended Metropolitan Regions (EMR) in China.With the rapid urbanization,the agglomeration of population and industries has emerged,which has led to dramatic changes of spatial structure and land use in this region.With data of high resolution TM remote sensing images and Google Earth maps,this paper identified and analyzed the spatial pattern of the Zhujiang River Delta EMR using Envy and ArcGIS tools.It was found that 1) the industrial land uses were expanding substantially,particularly on the bank sides of the Zhujiang River estuary;2) large-scale housing developments were concentrated in the fringe of metropolitan areas such as those of Guangzhou and Shenzhen;3) a regional transportation network with the spatial pattern of ″1 circle +2 pieces + 3 axes″ had significantly affected the location choice of manufacture enterprises.At the same time,both highly specialized land use and severely mixed land use patterns were identified.As a consequence of the latter,land use efficiency of the whole EMR areas was reduced.Moreover,ecologic and environmental problems were severe.Based on the above analysis,suggestions were given from the viewpoint of spatial safety,land use efficiency,and the reorganization of spatial structure in the Zhujiang River Delta EMR.     

不同收入水平的城市居民生活消费生态足迹测算与对比——以河南省开封市为例

本文运用生态足迹的理论和方法,以2009年开封市3个不同收入居民消费水平生活小区为例,采用居民生物资源和能源消费调查问卷数据,定量分析了2009年开封市不同收入水平小区居民的生活消费生态足迹。根据板桥小区、康平小区、龙成花园3 个小区的调查资料,分别计算了3个小区的生物资源消费和能源消费的生态足迹。结果表明:① 从3个小区人均生态足迹来看,总体上能源消耗的生态足迹较大;② 从3个小区居民生物消费的生态足迹来看,猪肉的人均生态足迹最大,奶制品次之,肉类食品和奶制品的生产需要较多的土地面积;③ 通过分析3个小区不同类型的人均生态足迹,板桥小区化石燃料用地和建筑用地所占的比重最大,其次是耕地和草地;收入消费水平越高的居民,生态足迹越大,收入消费水平越低的居民,生态足迹越小。证实了高收入水平居民对生态以及资源的占用程度要远远大于低收入水平居民,造成居民生态占用以及碳排放的不公。最后,提出了有针对性的对策建议。     

新型城镇化能否突破“胡焕庸线”——兼论“胡焕庸线”的地理学内涵

“胡焕庸线”提出80年来,在国际上产生深远影响。随着中国新型城镇化进程的全面推进,对胡焕庸线的研究急剧升温。在新的历史背景下,如何客观看待胡焕庸线成为亟待解决的一个问题。研究认为：胡焕庸线不仅是中国人口分布的分界线,也是重要的自然生态界线,这条界线的形成不以人的意志为转移,不宜人为去“打破”。同时,在新型城镇化背景下,应该树立理性思维,稳妥有序地推进城镇化进程,不断优化城镇化的空间分布格局。在全面放开二孩的新政策推动下,由于中国区域人口政策的差异性,东部和中部地区的人口有望实现较为明显的增长,西部地区增长相对缓慢,由此可能对胡焕庸线两侧的人口空间格局产生一定的影响。     

“行政区划本身也是一种重要资源”的理论创新与应用

行政区划是国家治理体系和组织结构的基本形式,也是中央政府统治和管理全国各地的有效手段,是事关国家政治、经济和社会发展全局的重大战略问题。就“行政区划本身也是一种重要资源”的论断进行多视角的分析,提出“行政区划资源论”这一全新的理论解读。分别从空间、权力、行政和政策角度探讨行政区划的资源属性,并从行政资源的空间配置、生产要素的优化配置、权力资源的空间整合、空间资源的优化重组和政策资源的空间载体等多个角度剖析行政区划的资源效应,最后提出应当将“行政区划资源论”这一新论断积极应用至主体功能区规划、空间规划、空间治理体系建设等实践领域,完善目前行政区划设置和调整的思路与要求,建立健全与国家发展战略及综合配套改革相适应的行政区划体系和管理框架。     

Influencing factors for formation of urban and rural spatial structure in metropolis fringe area—Taking Shuangliu County of Chengdu in China as a case

With rapid urbanization process, the pace of urban sprawl has been quickened and most metropolises have experienced expansions in leaps and bounds in suburbanization, which has greatly changed the urban and rural spatial structure of the metropolis fringe area. In this paper, Shuangliu County is taken as a case, since it is a typical fringe area of Chengdu Metropolis. Based on Landsat TM images of Chengdu City and Shuangliu County obtained in 1985, 2000 and 2004, characteristics of urban and rural spatial structure in Shuangliu County were analyzed, such as core-periphery spatial structure and some obvious integration trends. Then the influencing factors for the formation of urban and rural spatial structure were identified, including some natural, social, economic and political factors. According to the discussion of this paper, Shuangliu County is undergoing a key transition and reform period. Its formation of urban and rural spatial structure was affected not only by such common factors as the location, natural background, industrial transition, migration, etc., but also by some unique factors such as city planning and policy guidance, which played an important role in accelerating its uneven spatial structure. The understanding of the role of the influencing factors would be useful for carrying out spatial management and development planning of metropolis fringe area.
