西藏工布自然保护区森林生态系统涵养水源功能及其价值

The Function and Economic Value of Water Conservation of Forest Ecosystem in Gongbu Nature Reserve in Tibet

西藏工布自然保护区位于西藏林芝地区境内,是迄今为止国家批复投资最大的林业自然保护区建设工程。采用影子工程法,并根据国家林业局发布的《森林生态系统服务功能评估规范》,对工布自然保护区森林生态系统涵养水源功能进行了估算,结果表明:工布自然保护区森林生态系统涵养水源总价值为84.85亿元,而涵养水源功能仅仅是生态服务功能的一小部分,可见工布自然保护区的森林生态系统服务功能的生态价值非常大,也就是说,工布自然保护区具有极其重要的生态价值。

Gongbu Nature Reserve is in Tibet Nyingchi area,and is by far the largest construction of the forest reserves in China.The function and value of water conservation are evaluated by shadow project method based on the Specifications for Assessment of Forest Ecosystem Services in China promulgated by State Forestry Administration of China.The results showed that the value of water conservation is 84.85 billion yuan per year in Gongbu Nature Reserve.However,the function of soil conservation is only a fraction of the ecological functions.So the value of forest ecosystem service function in Gongbu Nature Reserve is very large,that is to say,it has a vital natural ecological value.
