草地生态系统服务功能及其价值评估研究进展

草地生态系统是维持自然生态系统格局、保护生态安全屏障、开展畜牧业生产和传承草原文化的基础。随着人类对草地生态系统服务功能不可替代性的深入认识,通过定量评估生态系统服务功能及其价值,对认识草地生态服务功能的重要性和生态资产增值具有重要的作用。在总结国内外生态系统服务功能及其价值文献基础上,对草地生态系统服务功能及其价值的内涵、生态服务价值评估方法及其特点和国内外研究现状进行了系统总结,分析了草地生态系统服务功能及其价值评估中存在的主要问题,提出了未来研究的发展方向。

Research progress in the ecosystem services function and value of grasslands

Grasslands not only maintain the integrity of natural ecosystem structure and act as an ecological safety barrier, but they also play an important role in supporting animal production and in inheriting grassland culture. Ecological services function is one of the key aspects of grassland research, and its value, through quantitatively evaluating ecological services function and value of grassland ecosystem, is the key for assessing the importance of ecological services of grassland ecosystem. This paper reviews the previous research on grassland ecosystem services function and its services value, the methods for evaluating ecological services, and presents domestic and overseas study conditions in this field. On this basis, some problems in previous studies were analyzed from research method, content and scale of ecological services function and its values, and a future potential study was proposed for grassland ecosystems.
