基于空间冲突的区域国土空间优化研究——以江苏省为例

Spatial Optimization of Regional Territory Based on Spatial Conflict:A Case Study of Jiangsu Province

空间冲突是国土空间优化乃至国土空间规划的基础。据此,构建了基于空间冲突的国土空间优化思路,并以自然资源禀赋条件优越、多宜性强,区域资源环境具有高承载性的江苏省为例,分析其经济社会持续快速发展所导致的耕地资源紧缺、局部地区环境负荷持续增大等空间冲突,以及生态、农业和城镇空间结构性矛盾,提出了基于限制性地域因子的国土空间优化模型,从而将生态保护极重要区域、农业生产适宜区域以及城镇建设适宜区域比例分别为:8.81%、54.24%、46.92%的主体功能冲突型国土空间,优化为生态空间、农业空间、城镇空间占比分别为14.46%、59.51%、26.03%的主体功能格局,体现了江苏作为经济强省、农业大省的人与自然和谐共生发展特征,为减缓生态、城镇、农业的空间冲突,科学开展国土空间治理提供了科学基础。

Space conflict is the basis of national spatial optimization and even national spatial planning.On this basis,the article constructs the national spatial optimization idea based on space conflict,and by natural resources endowment condition is superior,the more appropriate sex strong,regional resources and environment of high load bearing in jiangsu province as an example,the analysis of the sustained and rapid economic and social development caused by the shortage of arable land resources,regional environment and continuous increase of load space conflict,And ecological,agricultural and urban spatial structural contradictions,put forward the territorial space optimization model based on the restricted regional factors,thus the proportion of the most important regions for ecological protection,the suitable regions for agricultural production and the suitable regions for urban construction are respectively:8.81%,54.24% and 46.92% of the land space with main function conflict,and the main function pattern of ecological space,agricultural space and urban space accounted for 14.46%,59.51% and 26.03% respectively,reflecting the harmonious coexistence and development characteristics of human and nature in Jiangsu province,which is a strong economic province and a big agricultural province.It provides a scientific basis for mitigating the spatial conflict between ecology,town and agriculture and for carrying out territorial space governance scientifically.
