摘要
生态系统服务价值评价结果可为土地整理规划设计的决策提供科学依据,以便于提高农业生态系统生产力和生产效率,提高土地整理的效益,最终使土地整理达到可持续发展的目标。选取北京市延庆区王木营土地整理项目作为一个典型案例,运用中国学者提出的生态系统服务价值当量因子表,对该区生态系统服务功能经济价值进行了评价,得出土地整理前后的生态价值分别为142.13和156.12万元,增加率为9.84%。同时分析了生态系统服务功能经济价值变化的原因并对结果进行了讨论。
The result of ecosystem services assessment can provide a scientific basis for land use planning and design, so as to improve agricultural productivity and efficiency, improve the effectiveness of land consolidation and finally achieve the goal of sustainable development. This paper selects a land consolidation project at Wangmuying, Yanqing District, Beijing, as a typical case, and estimates its economic value of ecosystem services with the table of equivalent weight factor of economic value of ecosystem services advanced by Chinese scholars. The result shows that the ecosystem services before and after land consolidation are respectively 1. 421 3 and 1. 561 2 million, increasing by 9. 84%. The paper also analyzes the causes and outcomes of the changes.
