摘要
对鄂尔多斯遗鸥国家自然保护区遗鸥繁殖生境——尾闾湖泊湿地,从生态系统服务功能的"分项"和"准整体"两种角度出发,分别采用现行的价值评估方法和生态系统服务价值当量,结合研究区生态系统的服务功能分析以及2005年全国粮食及其他产品的价格水平,评估了研究区的生态系统服务价值,其分别为0.93亿元和1.48亿元,约为1.4万元/hm2和2.2万元/hm2。通过对两个结果的分析比较可知,研究区湿地生态系统服务功能的价值量在(1.0~1.5)亿元之间,其价值量的大小受选用方法、对生态系统服务功能各部分的认识及价格水平等因素的影响。
The National Ordos Relict Gull Nature Reserve is an important international wetland. Due to severe shortage of water from 2003 on, the habited environment of living and breeding for relic gull had been damaged badly. Taking the wetland in the core zone of the reserve as the target area, the authors studied the value of ecosystem service function. In the study, an internationally used ecosystem service evaluation method was adopted and the prices of food as well as other products in 2005 were referred. Two approaches, "decomposition-summation"and "quasi-integral estimation", were used. The results of the two approaches on the value of ecosystem service of the area were 93 million Yuan and 148 million Yuan, which are equivalent to 14,000 Yuan/hm^2 and 22,000 Yuan/hm^2, respectively. The reasons of such differences are related with the approach used, understanding on ecosystem value, and price level, etc. However, a canclusion can be made that the value of the wetland ecosystem is between 100 million Yuan and 150 million Yuan.
