庐山森林生态系统服务功能经济价值评估

Evaluation on Economic Value of Forest Ecology System Function of Lushan Mountain

从研究森林生态系统的效益出发,采用机会成本法、影子价格法、市场价格替代花费法等手段对江西省庐山森林生态系统涵养水源、保持土壤、净化空气、固定CO2等的生态系统服务功能进行了估算。得出该地区森林生态系统涵养水源的价值为93 421.146万元/a;保持土壤的价值为8 138.588万元/a;固定CO2的价值为2 419.622万元/a;净化空气的价值为7 439.799万元/a。其森林生态系统服务间接功能的总价值每年为111 419.156万元。

The ecosystem function of water conservation, soil conservation, air purification, carbon sequestration of Lushan mountain were evaluated by using the methods of opportunity cost approach, shadow price method, market price replacement cost method. The results showed that the value of water conservation, soil conservation, carbon sequestration and air purification were 934.211 46 million yuan/a, 81. 385 88 million yuan/a, 24. 196 22 million yuan/a and 74. 397 99 million yuan/a respectively, and which was amount to 1 114. 191 56 million yuan/a, which was the total ecosystem service function of forests in Lushan mountain.
