摘要
以GIS为平台,研究了长江上游森林生态系统的水源涵养功能。结果表明:常绿阔叶灌丛综合水源涵养量最大,占整个森林生态系统水源涵养总量的43.6%;亚热带山地落叶松林水源涵养量最小,占总量的0.08%。
The water conservation of the forest ecological system was studied based on GIS. The results showed that the water conservation of the long-green broadleaf shrubbery was the highest, being 43.6% of the total water conservation. And the water conservation of the subtropical mountain larch forest was the lowest, being 0.08% of the total.
