国土空间规划中生态空间和生态保护红线的划定

Demarcating ecological space and ecological protection red line under the framework of territory spatial planning

省级空间规划是为实现“多规合一”而开展的基础性制度尝试,其核心内容划定“三区三线”是通过科学分析自然与社会本底,对各类空间边界进行严格勘定,作为管控国土空间的抓手。生态空间和生态保护红线是“三区三线”中“生态先行”理念的载体。以《生态保护红线划定技术指南》为基础,对福建省开展基于资源环境承载能力评价和国土空间开发适宜性评价要求的陆上全域生态保护等级和保护优先序评价,探讨和实践省级空间规划中生态空间和生态保护红线的划分方法,以期为沿海多山省份的空间规划提供参考。结果显示:福建省生态空间陆域占比为78.76%,涵盖了88.07%的森林、71.23%的草地、64.44%的水域和47.72%的裸地;生态保护红线陆域占比为20.90%,以生物多样性维护红线、水源地保护及水源涵养红线为主。

Territorial space planning at the provincial level is a brand-new attempt of "multiple planning integration" fundamental regime. The core content is demarcating the "urban space, agriculture space, ecological space, urban development boundary, permanent basic farmland and ecological protection red line", to analyze natural and social background scientifically, which are the strict assignments of all kinds of space boundary, so as to strengthen national spatial control. The "ecological space and ecological protection red line" refered to "ecological space and ecological protection red line", which is the concrete embodiment of the "concept of ecology priority" in the construction of ecological civilization in the new era of China. The ecological protection red line is the core of ecological space, which has three characteristics: the strongly underlying constraints, the wide range of coverage and the high level of constraints. With full absorption of the "Technical Guideline for Demarcating the Red Line of Ecological Protection" promulgated by the Ministry of Environmental Protection, this study, taking the whole land area of Fujian province as an example, carried out double assignments of ecological protection level and ecological protection priority, based on the thought of ecological carrying capacity and suitability;and then discussed and practiced the demarcation of ecological space and ecological protection red line under the framework of provincial spatial planning, so as to put forward "multiple planning integration" and to be a useful reference for the demarcation of territorial space planning in coastal and mountainous provinces. The results show that, the whole area of Fujian ecological space and ecological protection red line is about 95932.88 square kilometers, accounting for 78.76% of the province's land area. The ecological protection red line is about 25461.39 square kilometers, taking 20.90% of the province's land area. The "biodiversity maintenance red line" and "water source protection and water conservation red line ", which were subordinated to the ecological protection red line, accounting for 11.96% and 6.26% of the province's land area. The "biodiversity maintenance red line" and "water source protection and water conservation red line" were concentrated in Wuyi Mountains, Daiyun mountain, Zhejiang-Fujian mountainous region, southern Fujian mountainous region and southeastern coastal area, which are mainly consistent with Fujian ecological function zones.
