摘要
目前,在整个陆地生态系统中研究最多的就是面积量很大的重要的森林生态系统,综合考虑涵养量估算技术和实用目的,本文提出森林水源涵养量就是森林拦截的可提供给人们利用的水量的定义,通过对森林水源涵养量概念厘定,结合九寨沟森林生态系统的实例,对九寨沟森林生态系统水源涵养状况进行分析,对九寨沟森林水源涵养量进行了估算。结果表明:九寨沟森林生态系统的年水源涵养量为1.60219×1012m3由此可见,在地区可持续发展进程中,森林生态系统的生态价值还是十分重要的。
Nowadays,the forest is the biggest and the most imprtant ecosystem in the land ecosystem.Taking assessment methods and practicality purpose into consideration,headwaters conservation through forest is defind as the amount of water held back by forest during precipitation.By determining the concept of headwaters conservation and its assessment methods,based on the amount of headwaters conservation from forest,the water conservation through forest ecosystem of Jiuzhaigou was assessed.The result shows that the benefits of water conserved through forest ecosystem within this region is about 1.60219×1012 m3 every year.Therefore it can be concluded that ecological benefits of forest ecosystem are significant in regional sustainable development.
