青藏高原草地生态系统服务功能体现在3个方面,即生态功能、生产功能和生活功能。生态功能为系统所固有。是系统维持和发展的基础;生产功能是影响草地生态系统服务功能发生改变的触发点;生活功能主要取决于生态功能和生产功能的平衡关系和管理状况,体现系统综合发展水平。充分理解和把握“三生功能”之间的互作关系,对青藏高原草地生态系统的维系与发展具有重要指导意义。
The functions of ecosystem in Tibetan grassland include ecological functions, production functions and living functions. Maintenance and development of the Tibetan grassland ecosystem mainly depend on its intrinsic ecological functions. The production tunctions play as a key role in the improvement of Tibetan grassland ecosystem. A balance between ecological and productive functions determines the level of the living functions, which reflects the development state of the integrated Tibetan grassland ecosystem management. It is very important to understand fully the interactions among "three functions" for maintenance and development of the Tibetan grassland ecosystem.
