| 摘 要： | 黑河下游的居延海湿地属中国干旱\,半干旱内陆河湖泊湿地，具有多种生态服务功能。利用市场价值法、造林成本法、影子工程法、费用替代法以及专家评估法等方法对居延海湿地生态系统服务功能价值进行评估。结果表明,居延海湿地生态系统的总生态服务价值为11 523.33万元·a-1,其中防风固沙价值为3 149.76万元·a-1，生物多样性维持为1 152.28万元·a-1，旅游价值为1 339.8万元·a-1，净化水体价值为2 240.7万元·a-1，大气调节价值为2 007.55万元·a-1，科研文化价值为1 504.3万元·a-1，而物质生产价值比较低，只有130万元·a-1。

| Abstract: | Wetland is amongst the richest life-supporting ecosystems on earth,and it is cradle of biological diversity,providing the water and primary productivity upon which countless species of plants and animals depend for survival.The Juyan Lake is located in the arid area of China.Based on the reference of the 17 major valuating parameters and methods proposed by Costanza et al and others,the market value approach,reforestation cost approach,shadow project method,and contingent valuation method are used to assess the wetland ecosystem service values of the Juyan Lake Wetland.Results show that the annual ecosystem service value of the Juyan Lake Wetland is about 11 523.33×104 Yuan in 2007,among which the sand fixation value occupies the highest proportion of about 3 149.76×104 Yuan;the gas regulation value is 2 007.55×104 Yuan;the biodiversity value is 1 152.28×104 Yuan;the cultural value is 1 504.3×104 Yuan;the recreation value is 1 339.8×104 Yuan;the material production value occupies the smallest proportion of about 130×104 yuan. |
