摘要

[目的] 研究江苏省常州市资源环境综合承载力情况，明确国土空间开发与利用方向，为该区土地与人口的空间布局优化提供决策依据。[方法] 基于2010—2019年多源国土空间数据，构建多因素多因子综合判别模型。[结果] 常州市资源环境综合承载力呈现出显著的东高西低，平原高山地丘陵区低等空间分异特征。此外，基于未来土地资源的粮食安全保障水平预测2030年常州市人口承载指数高达1.27，显著高于国际警戒水平。[结论] 常州市空间开发程度、自然本底和基础设施条件对区域资源环境综合承载力水平具有显著的约束，且人口处于超载状态。

Abstract

[Objective] The comprehensive carrying capacity of resource and environment in Changzhou City of Jiangsu Province was studied

in order to clarify the direction of land space development and utilization

and to provide decision-making references for the spatial allocation optimization of land and population.[Methods] Based on multi-source land and space data from 2010 to 2019

a multi-index and multi-factor synthetic discriminant model was constructed. [Results] The comprehensive carrying capacity of resources and environment in Changzhou City presented significant spatial differences

such as high in the east and low in the west

high in the plain and low in the mountainous and hilly areas. Moreover

based on the food security guarantee level calculated with future land resources

the population carrying index of Changzhou City in 2030 would be as high as 1.27

which was significantly higher than the international alert level. [Conclusion] The spatial development degree

natural background and infrastructure conditions have significant constraints on the comprehensive carrying capacity of resources and environment in Changzhou City

and the population is in a state of overloading.
