基于主导生态功能的江西省国土空间生态修复分区研究

以地域分异特征、主导生态功能、典型生态问题为基础依据,探讨江西省国土空间生态修复分区,为江西省编制和实施生态修复规划、实现国土空间管控提供科技支撑。在研究方法上,以“生命共同体理论”“三生协调理论”“适宜性管理”等理论为指导,基于主体功能区划和生态功能区划,综合“三生”空间实际生态问题及综合整治需求,采用多因素综合空间分析法,“自上而下”和“自下而上”相结合,实现国土空间生态修复三级分区。研究结果表明,可将江西省国土空间生态修复区域划为赣北平原湖泊生态修复区、赣中丘陵盆地生态修复区、赣西山地丘陵生态修复区、赣南山地丘陵生态修复区、赣东丘陵山地生态修复区5个大区及24个亚区和42个修复小区。通过江西省国土空间生态修复三级分区,摸清国土空间地域特征,明确生态主导功能,确定生态修复重点区域,承上启下,为实施生态修复工程和国土空间管治提供决策依据,为实现国土空间整体保护、系统修复、综合治理提供科技途径。

Territorial land zoning for ecological restoration in Jiangxi Province based on dominant ecological function

In conderations of the regional differentiation characteristics, dominant ecological functions and typical ecological problems, this article explores the territorial land zoning for ecological restoration in Jiangxi Province to provide scientific and technological supports for the preparation and implementation of ecological restoration plans as well as for the realization of land management and control in Jiangxi Province. Guided by the ideas of life community, harmonious rural development, and suitable management, by delineating the principle and ecological functional spaces, and taking into account both the practical ecological problems associated with rural development and the demands for comprehensive development, we use the multi-factor comprehensive spatial analysis method, combined with the “top-down”, “bottom-up” approach, to achieve the three-level ecological restoration of territorial land. The territorial land zoning divides the plains and lakes in northern Jiangxi and the hills and basins in central, western, southern, and eastern Jiangxi into 5 level-1, 24 level-2, and 70 level-3 ecological restoration zones. Through the three-level zoning, the characteristics of the territorial land are clarified, the leading ecosystem function are specified, and the key areas of ecological restoration are identified. It provides a decision-making basis for the implementation of ecological restoration projects and land governance as well as a scientific and technological approach for the overall protection, systematic restoration, and comprehensive governance of territorial land.
