| 摘 要： | 以石羊河流域下游民勤为主要研究范围, 对民勤县1994-2005年12 a间生态系统服务的价值进行了估算和对比分析. 结果表明, 1994年区域生态系统服务的总价值为9.976×10~8元, 2005年区域生态系统服务的总价值为8.475×10~8元, 12 a来区域内的生态系统服务价值下降了近1.501×10~8元. 由于缺乏对盐碱地、建筑用地等服务价值的相关研究信息, 该结果仅是对民勤生态系统服务价值的保守估算. 总的来说, 研究区域生态系统服务价值呈现快速下降趋势.

| Abstract: | The evaluation of ecosystem service's value has some complexity and uncertainty. In the recent years, the evaluation of ecosystem service's value has become a hot issue and front of studying the sustainable development, ecological economics and ecology. The evaluation introduces the ecosystem evaluation into the national economic accounting system, revising the GDP, and promoting the regional sustainable development.Based on the statistical data of the lower reaches of Shiyang River, especially in Minqin Oasis, from1994 to 2005, the ecosystem service's value of the Minqin County is estimated in this paper. The result shows that the annual value of the ecosystem service in the lower reaches was 99.76×10~8 Yuan in 1994, and 84.75×10~8 Yuan in 2005. During the past 10 years, the value of the ecosystem service reduces 15.01×10~8 Yuan, with a decreasing rate of 1.501×10~8 Yuan per year. Owing to lack of relevant data and information on the service's value of saline-alkali land and construction land, etc., this result is only a conservative valuation of ecosystem service′s value in the Minqin oasis. |
