文章以艾比湖流域为例,采用谢高地等人的中国陆地生态系统单位面积生态服务价值表,计算了1990、2001和2005年艾比湖流域的生态服务价值。研究结果表明:(1)研究时段内,从1990年到2005年艾比湖流域的生态服务总价值是增加的,共增加了8.4943亿元。(2)通过敏感性分析表明,生态系统服务价值系数的改变对生态系统总服务价值影响不明显,研究结果是可信的。
This paper took Ebinur lake area as a case to analyze the ecosystem service value in 1990,2001 and 2005,by applying the ecosystem service value coefficient of different Chinese ecosystem types published by Xie Gaodi. The results showed that (1) from 1990 to 2005, the ecosystem service value of the area under study increases, an increase of 8.4943×108 yuan, and (2) the estimated results are relatively reasonable by calculating the coefficient of sensitivity.
