多类型保护地生态承载力核算模型及应用

生态承载力核算是进行保护地科学保护和有效利用的重要基础。多类型保护地是多种类型的保护地分布集中、相邻相连、交叉重叠的地理空间。研究将多类型保护地功能空间与生态系统服务相对应,划分为生态空间、生产空间、生活空间和游憩空间,在此基础上将多类型保护地生态承载力定义为生态系统在这四类空间中维持其重要生态系统服务功能的能力,并将其划分为自然基础承载力、社会经济活动承载力以及游憩承载力,构建了适用于多类型保护地的生态承载力核算框架模型。以三江源国家公园黄河源园区为案例区,进行了生态承载力核算。研究能够为多类型保护地经济建设规模、结构与布局优化调控研究提供科学依据。

Ecological carrying capacity accounting model and application in multi-type protected areas

Ecological carrying capacity accounting is an important foundation of scientific protection and effective use of the protected areas. Multi-type protected areas are geographically distributed, adjacently connected, and overlapped areas. This study relates the functional space of multiple types of protected areas and the ecosystem services, and divides them into the ecological space, production space, living space and recreation space. On this basis, the ecological carrying capacity of multiple types of protected areas is defined as the ecosystem''s ability to maintain its ecosystem services in those four types of space. The ecological carrying capacity of multiple types of protected areas is divided into natural foundational carrying capacity, socio-economic activity carrying capacity, and recreational carrying capacity. An ecological carrying capacity accounting framework model suitable for multi-type protected areas is constructed. This study takes the Yellow River Source Park of Sanjiangyuan National Park as a case area to evaluate its ecological carrying capacity. This study can provide a scientific foundation for research on the economic construction scale, structure and layout optimization of multi-type protected areas.
