摘要:

明确国土空间生态修复分区是有序实施国土整治与生态修复的前提与基础。重庆市是长江上游生态屏障的最后一道关口,在国家生态安全格局中的战略地位突出。本文以重庆市为例,探讨基于适应性循环模型的国土空间生态修复分区研究框架,构建评价指标体系诊断国土空间系统潜力、连通度和韧性3维属性的时空演变趋势,识别县域单元所处适应性循环阶段,划定国土空间生态修复分区,并明确基于分区的生态修复策略。结果表明:① 2000—2020年重庆市国土空间系统3维属性整体呈现东高西低的空间特征。当前各县域单元大多处于重组阶段、开发阶段和协调开发阶段,少部分处于保护阶段,尚未进入释放阶段。② 重庆市国土空间生态修复分区包含4个大区和9个亚区。总体而言,生态修复区应关注建成区的系统性生态修复工程,加强环境综合改良与治理力度;生态提升区应逐步提高生态保护修复工程的实施标准,优化各类生态要素的协调度,提升综合生态效益;生态控制区应限制国土空间开发强度,降低人类活动干扰的负面影响;生态保育区应优化自然生态系统功能,加强生态保护区管理与生态问题治理。

Abstract:

A clear ecological restoration zoning of territorial space is the prerequisite and foundation for the orderly implementation of land remediation and ecological restoration projects. Chongqing is the last gateway to the ecological barrier of the upper reaches of the Yangtze River, with a prominent strategic position in the ecological security pattern of China. Taking Chongqing as an example, this study explored the framework of ecological restoration zoning based on the adaptive cycle model, constructed an index system to evaluate the spatio-temporal characteristics of the three-dimensional attributes of potential, connectedness and resilience of the city's territorial space system, identified the adaptive cycle phase of each county, and discussed its ecological restoration of territorial space. The results show that: (1) The spatial distribution of three-dimensional attributes in the study area from 2000 to 2020 presents a pattern of high in the east and low in the west. Most of the counties in Chongqing are in the reorganization phase, exploitation phase and coordinated exploitation phase, a few are in the conservation phase, and no county has yet entered the release phase. (2) Ecological restoration zoning of the city includes 4 zones and 9 subzones. In general, the ecological restoration zone focuses on systematic ecological restoration projects in built-up areas and strengthen comprehensive environmental improvement and treatment efforts; the ecological enhancement zone should gradually improve the implementation standards of ecological protection and restoration projects, optimize the coordination of various ecological elements, and enhance comprehensive ecological benefits; the ecological control zone should limit the intensity of territorial space development and reduce the negative impact of human activities on ecosystems; the ecological conservation zone should optimize the functions of natural ecosystems and strengthen the management of ecological reserves and the solution to ecological problems.
