粮食生产核心区综合承载力评价研究——以河南省商丘市为例

提高粮食生产核心区综合承载力是实施国家主体功能区战略、推进粮食生产核心区建设的重要价值取向。以综合承载力研究成果为基础，从我国粮食生产核心区城乡三次产业承载水平的角度，初步构建评价区域综合承载力的影响因子和模型，对商丘市2000-2009年城乡三次产业综合承载力实证研究的结果表明：当前农村呈现超载状态，城镇虽尚可载但水平不足，城乡综合承载力与现有人口规模基本持平，区域城镇化和城乡统筹发展有待提速。因此，粮食生产核心区应着力发展现代农业、大力提高城市综合承载力、不断拓展城市市区和功能新区发展空间。

Study on the Assessment of the Comprehensive Carrying Capacity in Core Grain-production Districts --Taking Shangqiu City, Henan Province as an Example

To improve the Comprehensive Carrying Capacity （CCC） in Core Grain-production Districts （CGD） is an important goal for the implementation of Principal Functional Region strategy and the construction of CGD. Based on the researching progress analysis of CCC, this paper initially constructs CCC impact index and the CCC assessment model from the point of urban-rural industrial carrying capacity, and takes Shangqiu City as an example to empirically research its industrial carrying capacity in 2000 -2009. Studies show that the current status of rural CCC is overloading, the urban CCC is strong but can hold on less, the overall level of urban-rural CCC is as fiat as the existing population size. Then it points that regional urbanization and urban- rural coordinating development is to be accelerated. Therefore, to improve CCC, steps should be taken in CGD to pay close attention to modern agriculture, to enhance urban CCC vigorously, and to extend the development space of urban district and new functional districts.
