土地资源配置与人口·经济·产业·资源空间协调性分析

Study on the Consistency between Land Quotas Distribution and Population,Economy,Industry and Resource

以年度新增建设用地为切入点,构建土地与人口、经济、产业、耕地资源协调性系数,以江苏省13个地级市为研究对象,对年度新增建设用地配置数量与人口分布、经济发展、产业结构与耕地资源协调性的时空演变以及空间分异特征进行评价。研究结果表明:①江苏省年度新增建设用地配置与人口分布、经济发展、产业结构、耕地禀赋“两两”空间协调性增强,但各地级市协调性系数空间差异显著。②江苏省各地级市年度新增建设用地配置与人口分布、经济发展、产业结构、耕地资源综合协调性整体上呈“补丁”状分布。③经济、人口、产业向大城市集聚的同时,土地资源配置没有相应跟进,集聚趋势反而呈现下降态势。土地资源集聚并非是源于规模经济的内在要求,也不是在市场机制下配置的结果,而是源于行政干预追求区域发展平衡的结果,这不仅可能带来效率损失的代价,而且并不能带来区域公平发展的结果。

The distribution of land resource is very important for urbanization,economic development,industry structure upgrading and farmland protection.The spatio-temporal consistency between land quotas distribution and population,economy,industry and farmland in Jiangsu Province has been evaluated by constructing the Consistency of Land and Population(Economy,Industry and Farmland).The main results are as follows:①The consistency between land quotas and population(economy,industry,or farmland)in Jiangsu was improved,but with huge spatial differences among municipalities.②The overall consistency in municipalities was varied.③When economy,population and industry agglomerate in metropolis,land quotas do not follow and the agglomerated tendency was decreasing.The land quotas agglomeration was intervened by governmental forces rather than market forces,which may bring economic efficiency loss and cannot decrease regional gaps.
