摘要:

以西北生态脆弱区甘肃省为研究对象,基于自然地理和社会经济数据,运用InVEST模型、CASA模型和ArcGIS空间分析等方法分析甘肃省生态服务功能及其权衡协同关系,探讨权衡协同关系下生态功能分区的优化方案。结果表明:(1) 2000—2020年,由于退耕还林等大规模生态建设工程促使甘肃省生态功能较强的林地、草地、河流水面、湖泊水面等地类增加,固碳量、生境质量、土壤保持和产水量4种生态服务均呈现出波动上升趋势。(2) 权衡协同关系中,生境质量-产水量、固碳量-产水量、土壤保持-生境质量表现为中等协同关系,土壤保持-固碳量、土壤保持-产水量、生境质量-固碳量表现为强协同关系。(3) 利用K-means聚类将甘肃省划分为经济-文化发展区、生境质量-固碳优先区、土壤保持-固碳优先区、生物多样-土壤保持区、水土综合保育区和生态服务综合保育区6种生态分区,将权衡协同关系纳入生态系统服务簇分区优化,需优化区占全省面积的3.07%。通过综合分析生态服务相似性和差异性,形成生态系统服务簇后充分考虑其分区内部的权衡协同关系,对传统生态分区进行优化调整,提出增强协同、缓解权衡的空间差异化治理措施。

Abstract:

Using physical geographic and socioeconomic data, we analyzed the ecological service functions and their trade-off synergistic relationship in Gansu Province, which is an ecologically fragile area in northwest China. We explored the optimization of ecological function zoning under a trade-off synergistic relationship by applying the InVEST model, CASA model, and ArcGIS spatial analysis. The results were as follows: (1) From 2000 to 2020, because of large-scale ecological construction projects, such as the return of farmland to forests, the ecological functions of Gansu Province (e.g., forest land, grassland, river water surface, and lake water surface) increased, and four kinds of ecological services (i.e., carbon sequestration, habitat quality, soil retention, and water production) showed fluctuating upward trends. (2) In the trade-off synergistic relationship, the habitat quality-water production, carbon sequestration-water production, soil retention-habitat quality, and carbon sequestration-water production showed medium to high levels of ecological services. Habitat quality-soil conservation showed moderate synergistic relationships, whereas soil conservation-carbon sequestration, soil conservation-water yield, and habitat quality-carbon sequestration showed strong synergistic relationships. (3) On the basis of K-means clustering, Gansu Province was divided into six ecological zones: economic-cultural development zone, habitat quality-carbon sequestration priority zone, soil conservation-carbon sequestration priority zone, biodiversity-soil conservation zone, soil and water conservation zone, and ecological services conservation zone. The trade-off synergistic relationships were incorporated in the optimization of ecosystem service cluster zoning, and the area to be optimized accounted for 3.07% of the province’s area. By comprehensively analyzing the similarities and differences of ecosystem services and forming ecosystem service clusters with full consideration of the trade-off synergistic relationship within zones, the traditional ecological zoning was optimized and adjusted, and spatially differentiated governance measures were proposed to enhance synergies and mitigate trade-offs.
