生态系统服务的量化与评估

Measurement and Assessment of Ecosystem Services

随着生态系统服务研究的深入,从供需角度量化和评估生态系统服务成为生态管理的关键技术.基于生态系统服务的理解和已有研究的比较分析,论文针对当前量化和评估手段的不足,在环境系统承载力的框架下提出采用综合叶面积指数表征生态系统服务,并利用生态承载剩余率评估生态系统服务的承载状况.选择了宁波市进行案例研究,验证量化和评估方法的科学性和实用性.

With the process of research on ecosystem services, it is more important to measure and assess ecosystem services in decision making of ecological management. By using comparison analysis, a review of the previous methods has been made and most of them could not be applicable to measure the ecosystem services in the framework of carrying capacity of the environment. The sum of leaf area index is selected to measure ecosystem services and a carrying capacity surplus ratio model is supposed to assess the supply and demand of ecosystem services in an area. The new method is validated in the case study of Ningbo City in China.
