摘要
运用市场价值法、影子工程法、替代费用法等生态经济学方法对流溪河林场森林生态系统服务功能的价值进行了评估。研究结果表明:流溪河林场森林生态系统服务功能的总价值为6.18×108 yuan.a-1,主要的生态系统服务价值为间接价值,其中涵养水源价值居首位。各项服务功能的价值如下:林产品价值为6.03×107 yuan.a-1,涵养水源价值为4.50×108 yuan.a-1,土壤保持价值为1.46×107 yuan.a-1,固碳放氧价值为5.80×107 yuan.a-1,净化空气价值为2.42×107 yuan.a-1,旅游价值为3.00×106 yuan.a-1,生物多样性维护价值为7.61×106 yuan.a-1。
The forest ecosystem service in Liu-Xi River Forest Farm was evaluated by market valuation method, shadow engineering method, substitute expense method and so on. The results showed that the total value of the ecosystem service was estimated up to 6.18 × 10^8 yuan·a^-1, and that the main value of ecosystem service was indirect value and the most value was water reservation. The value of each service was as follow： the timber was worth 6.03 × 10^7 yuan·a^-1; water reservation was worth 4.50 × 10^8 yuan·a^-1; soil conservation was worth 1.46 × 10^7 yuan·a^-1; carbon fixation and oxygen release was worth 5.80 × 10^7 yuan·a^-1; air purification was worth 2.42 × 10^7 yuan·a^-1;eco-tourism was worth 3.00 × 10^6 yuan·a^-1, and biodiversity maintenance was worth 7.61 × 10^6 yuan·a^-1.
