【摘要】：自21世纪以来,中国城市化率以超过1个百分点的速度逐年增长。城市建设用地作为城市化的载体,在高速发展的城市化阶段,呈现出快速扩张的趋势。然而,在城市建设用地快速增长的过程中存在的问题日益凸显,尤其是城市建设用地的需求与土地供应有限性的矛盾日益尖锐。因此,本文试图通过对城市建设用地变化的过程、特征和空间差异的研究,探索产生变化的机制,以促进城市化健康和可持续发展。江苏作为东部发展的战略支点之一,同样面临这些问题。因此,本文选择经济发达、人口城市化水平较高的江苏省作为研究对象,围绕江苏省城市建设用地变化特征及其影响因素的空间差异性展开研究。首先,本文以江苏省13个地级市为例,基于2001-2015年江苏省城市建设用地数据,从建设用地绝对规模和相对规模、变化动态度、人均建设用地、占用耕地情况、建设用地结构信息熵等方面分析了江苏省城市建设用地规模与结构变化特征及区域差异。其次,在借鉴国内外关于城市建设用地驱动机制研究的基础上,从经济、社会、环境、文化、政策等方面对影响城市建设用地变化的因素进行了定性分析。基于此,构建了影响江苏省城市建设用地变化驱动指标体系,利用典型相关分析法求取各指标对城市建设用地变化的作用力大小,再运用主成分分析法进一步筛选指标,最后用逐步回归法得到江苏省城市建设用地变化的主导驱动因子。最后,理清江苏省13市城市建设用地变化主导驱动因子之间的共性和差异性。
[Abstract]:Since the 21 st century, China's urbanization rate has increased by more than 1 percentage point year by year. As a carrier of urbanization, urban construction land has a tendency of rapid expansion in the stage of rapid development of urbanization. However, in the process of rapid growth of urban construction land, the problems are increasingly prominent, especially the contradiction between the demand for urban construction land and the limited supply of land is increasingly sharp. Therefore, this paper attempts to explore the mechanism of change through the study of the process, characteristics and spatial differences of urban construction land change, in order to promote the healthy and sustainable development of urbanization. Jiangsu, as one of the strategic fulcrum of eastern development, also faces these problems. Therefore, this paper chooses Jiangsu Province, which has developed economy and high level of population urbanization, as the research object, and studies the spatial difference of urban construction land change characteristics and its influencing factors in Jiangsu Province. First of all, taking 13 prefecture-level cities in Jiangsu Province as an example, based on the data of urban construction land in Jiangsu Province from 2001 to 2015, from the absolute scale and relative scale of construction land, dynamic degree of change, per capita construction land, occupation of cultivated land, Based on the information entropy of construction land structure, this paper analyzes the characteristics and regional differences of the scale and structure of urban construction land in Jiangsu Province. Secondly, on the basis of studying the driving mechanism of urban construction land at home and abroad, this paper qualitatively analyzes the factors influencing the change of urban construction land from the aspects of economy, society, environment, culture, policy and so on. Based on this, the driving index system of urban construction land change in Jiangsu Province is constructed. The force of each index on the change of urban construction land is obtained by using canonical correlation analysis method, and then the principal component analysis is used to further screen the index. Finally, the main driving factors of urban construction land change in Jiangsu Province are obtained by stepwise regression method. Finally, the commonness and difference between the leading driving factors of urban construction land change in 13 cities of Jiangsu Province are clarified.
