城镇化与粮食生产水土资源的时空耦合协调

Study on Temporal and Spatial Coupling Coordination of Urbanization and Water-Soil Resources of Grain Production

城镇化进程中,如何节约和合理利用粮食生产水土资源,促进城镇化与粮食生产水土资源的协调发展,是我国当前面临的一个非常现实和重要的问题。文章在对我国1998—2013年城镇化和粮食生产水土资源发展趋势进行描述性分析基础上,运用耦合协调函数,从时间和空间两个角度,对我国以及各功能区城镇化和粮食生产水土资源的耦合协调度进行了测算和比较。结论表明：1从时序上来看,我国城镇化与粮食生产水土资源的耦合协调值一直维持在0.41~0.46之间,耦合协调状况不是很理想,各功能区都面临着＂濒临失调＂;2从空间上来看,我国各功能区城镇化与粮食生产水土资源的耦合协调度存在省际差异。

In the process of urbanization in China, to save and rationally utilize the water and soil resources of grain production and to promote the coordinated development of urbanization and water and soil resources of grain production is currently a very realistic and important problem that our country is facing. Based on the descriptive analysis of urbanization and the water and soil resources of grain production in our country from 1998 to 2013, from the perspective of time and space, by using the coupling coordination function, this article calculated and compared the coupling coordination degree of urbanization and the water and soil resources of grain production in each functional area. The research results show that：（1） From the temporal point of view, the coupling coordination degree of urbanization and the water and soil resources of grain production has been maintaining between 0.41- 0.46, and the coupling coordination situation is not very idea, each functional area facing the situation of＂on the verge of imbalance＂;（2） From the spatial point of view, the coupling coordination degree has differences between provinces.
