Evaluation of Forest Ecosystem Service Functions in Liaoning Xianrendong nature reserve

本文以仙人洞自然保护区为研究对象,研究保护区在涵养水源、净化空气、保持土壤、固定CO_2和释放O_2等方面的功能。采用市场价值法、影子工程法和机会成本法等对保护区生态系统服务功能价值进行评估,由此得出其生态服务功能价值为8 267.54万元/a。其中林产品价值为152.17万元,涵养水源为40.64万元,保持土壤为3 058.08万元,固碳制氧为130.77万元,净化空气为385.88万元,游憩价值为4 500万元。

With the research object Xianrendong nature reserve, it studies the ecosystem functions on water conservation, air purification, soil conservation, Carbon fixation and Oxygen release in the nature reserve. The value of the forest ecosystem services of the nature reserve are evaluated by using the methods of market-method, shadowengineering method and opportunity-cost, and so on. The resulting value of its ecosystem services is 82.6754 million yuan every year, of which, 1.5217 million yuan for the product of forest, 0.4064 million yuan for water conservation, 30.5808 million yuan for soil conservation, 1.3077 million yuan for Carbon fixation and Oxygen release, 3.8588 million yuan for air purification, 45.00 million yuan for tourism.
