为引起各界对森林生态系统的重视 ,推进西北地区生态环境建设 ,采用影子工程法、市场价值法、替代花费法、机会成本法、收益资本化法等 ,对祁连山森林生态系统服务功能进行评估 ,得出祁连山每年森林生态系统服务功能总价值为 2 4 30亿元。其中涵养水源为 9 30亿元 ,保育土壤为 5 6 4亿元 ,固碳制氧为 2 6 91 39万元 ,净化空气为 7 4 1亿元 ,保护生物多样性 1 5 1亿元 ,森林景观与游憩价值 16 87 5 0万元。
In order to cause the attention of society and people to the forest ecosystem, and advance the ecological environment conservation in the Northwest China, value of the forest ecosystem services of Qilian mountain in Gansu province were evaluated by using the methods of shadow engineering, market price, substitution expenditure, opportunity-cost, capitalized returns, and so on.
