宁夏沿黄城市群人口与经济时空耦合研究

Study on the Space-time Coupling between Population and Economic in Urban Agglomerations along the Yellow River in Ningxia

借助综合指数模型、协调发展度模型、GIS空间分析等技术,对沿黄城市群1990-2013年人口与经济的时空耦合关系进行研究。结果表明:沿黄城市群人口与经济的发展水平格局基本一致在时间上呈现先慢后快上升趋势,在空间上,呈现出北高南低的分布状态,人口与经济的协调发展水平向均衡方向演进,整体处于协调发展阶段;资源禀赋、国家政策、区位条件、自然本底、城市等级是影响城市群人口与经济发展的主要因素。

This paper studied the temporal-spatial structural characteristics of population and economy in urban agglomerations along the Yellow River in Ningxia province by using the comprehensive evaluation index, coordinated development degree method and spatial analysis tool. The results showed that：The coordinated development level of population and economy showed a trend of ＂slow in the first and fast in the next＂ from 1990 to 2013, and the distribution on the space of this two system presenting a pattern of ＂strong in the North and weak in the South＂; Population and economy move to the spatial equilibrium and generally at the stage of coordination; The resource endowment, national policy, positional condition, natural environment and urban hierarchy are the main factors that affect the development of population and economy.
