【摘要】：随着我国城镇化发展加速,土地功能的优化速度和土地效益的产出速度与其结构的快速变化形成不匹配模式,人地矛盾问题随之产生。同时随着城市圈和城市群的形成,城市发展所带来的巨大利益和副作用也会辐射到周边的其他城市。因此根据我国土地科学发展现状,立足于健康层面的系统性分析土地的发展情况,将为其可持续化发展提供基础;同时确定不同城市土地利用系统健康水平的空间关联性,可以全面和系统的了解我国土地利用的空间发展情况,对土地利用的全局规划和整体部署具有重要指导意义。从现有文献分析来看,城市土地利用系统健康的研究内容主要集中在不同时间段上土地利用的评价差异分析。针对空间层面分析并不多见,因此本文在丰富理论研究的基础上,对土地利用资源、社会、经济和空间交互关系进行研究,研究结果有一定的应用参考价值。作者通过文献分析,构建城市土地利用系统健康水平空间关联性概念模型,采取定性分析提取研究中的关键因素;在构建指标体系的基础上,参考熵值法、模糊综合评价法和探索性空间统计分析(ESDA)方法构建城市土地利用系统健康水平测度模型和空间关联性模型。旨在评价其健康程度的基础上,揭示城市之间土地利用系统健康程度的空间关联特征,并从空间局部异质性角度揭示其全局空间自相关的本质和局部地区对于全局空间自相关的贡献程度。最后,本文以重庆市主城九区作为实证研究对象,借助SPSS、Arcgis 10.2和Geoda等软件对研究区域2010年和2015年两期数据进行分析,结果表明:研究区域整体土地利用系统健康程度呈上升趋势,且处于“临界健康”的区域比例较大,区域健康水平分布由“环状辐射”趋势向“两级分化”趋势转移;研究区土地利用系统健康水平全局空间自相关性逐步增强,由随机分布转变为集聚分布。部分“高低”集聚或“低高”集聚的区域受到周边区域健康程度影响,向“高高”集聚或“低低”集聚靠拢,且2015年“高健康”中心的向南转移和“低健康”中心在北部的形成,不仅造成区域整体健康程度的“两级分化”,也导致其健康程度全局空间集聚性增强。因此政府应当结合区域内土地利用系统健康程度的空间变化和分布情况提出适当的政策手段,确保土地资源的合理利用。
[Abstract]:With the rapid development of urbanization in China, the optimization speed of land function and the output speed of land benefit are not matched with the rapid change of its structure, and the contradiction between man and land comes into being. At the same time, with the formation of urban circles and urban agglomerations, the huge benefits and side effects brought by urban development will also radiate to other surrounding cities. Therefore, according to the present situation of land science development in China, the systematic analysis of land development based on health level will provide the basis for its sustainable development. At the same time, the spatial correlation of the health level of different urban land use systems can be determined, which can comprehensively and systematically understand the spatial development of land use in China, and has an important guiding significance for the global planning and overall deployment of land use. From the analysis of the existing literature, the research contents of urban land use system health mainly focus on the analysis of land use evaluation difference in different time periods. The spatial level analysis is rare, so this paper studies the interaction of land use resources, society, economy and space on the basis of rich theoretical research. The results of the research have certain application reference value. Based on the literature analysis, the author constructs the concept model of spatial correlation of urban land use system health level, and takes qualitative analysis to extract the key factors in the research. On the basis of constructing index system, reference entropy method, fuzzy comprehensive evaluation method and exploratory spatial statistical analysis (ESDA) method are used to construct the health level measurement model and spatial correlation model of urban land use system. On the basis of evaluating their health, the purpose of this paper is to reveal the spatial correlation characteristics of the health degree of land use system among cities. The nature of global spatial autocorrelation and the contribution of local areas to global spatial autocorrelation are revealed from the perspective of spatial local heterogeneity. Finally, this paper takes the nine districts of Chongqing main city as the empirical research object, with the help of SPSS,Arcgis 10.2 and Geoda software to analyze the data of the two periods of 2010 and 2015. The results showed that the health degree of the whole land use system in the study area showed an upward trend, and the proportion of the region in the "critical health" was larger, and the distribution of regional health level shifted from the trend of "circular radiation" to the trend of "two-level differentiation". The global spatial autocorrelation of the health level of land use system in the study area was gradually enhanced, from random distribution to agglomeration distribution. Some "high and low" or "low" agglomeration areas are affected by the health of the surrounding regions, and they tend to "high" agglomeration or "low" agglomeration. In 2015, the transfer of "high health" center to the south and the formation of "low health" center in the north not only resulted in the "two-level differentiation" of the overall health degree of the region, but also resulted in the enhancement of the global spatial concentration of the health degree. Therefore, the government should put forward appropriate policy measures to ensure the rational use of land resources by combining the spatial changes and distribution of the health degree of land use system in the region.
