摘要
草地是我国陆地面积最大的生态系统类型,对维持我国自然生态系统格局、功能和过程具有特殊的生态意义。目前,草地退化导致的区域生态问题越来越突出,评价我国草地资源生态服务功能的经济价值,尤其是其潜在的生态调节功能和生命支持功能的价值,对于制定合理的区域生态保护和经济开发决策、保护和恢复草地生态系统具有重要意义。本文在阐明草地生态系统服务功能内涵基础上,再叙述2003年即千年生态系统框架提出以来我国草地生态系统服务功能价值研究现状,并对研究中存在的问题和发展方向进行总结,旨在为区域及全国尺度开展草地生态系统服务功能评价研究奠定基础。
Grassland ecosystem is the biggest one in China terrestrial ecosystems, and plays special role maintaining the structure, functions and ecological processes of natural ecosystems. At present, a series of ecological problems are becoming more and more serious because of grassland degradation in some regions. One of the essential reasons is that some important ecological functions of grassland ecosystem and their values are neglected. The economic valuation of grassland ecosystem services, especially the regulating and supporting services that are remarkable but unfamiliar by public, will help to the conservation, reclamation and rational development of grassland resources in China. The paper clarified the connotation of grassland ecosystem services function and described evaluating status that the ecosystem services of China grassland after A.D.2003 or proposed frame of the millennium ecosystem, at the same time, it summarized existing problems and direction for research.It will establish foundation for evaluating the ecosystem services of China grassland in Region and nationwide.
