摘要
博斯腾湖具有丰富的水产与芦苇资源,对当地人的生产、生活起着支撑作用。因此,对其生态服务功能进行评估,能更好地掌握当前湖泊的生态服务状态,为流域的后期开发提供参考。通过博斯腾湖的流域特点与实际情况,建立起由4个要素、12个指标所组成的博斯腾湖生态服务功能状态评估体系。应用系统多级灰关联综合评价方法对该体系进行评估,获取了该流域2001—2012年的生态服务功能状态等级。研究结果表明,2001—2012年博斯腾湖生态服务功能综合状态指数等级为"不太好",平均分值为67.60分,总体呈先下降后上升趋势,因此应联系实际更好地开发博斯腾湖流域的生态服务功能。
Bosten Lake has abundant resources of aquatic product and phragmites communis and plays an impor- tant role in the local people＇s production and life. Therefore, it is necessary to evaluate the ecosystem services function of Bosten Lake for better understanding its ecosystem services grade and providing the reference for the later develop- ment of Bosten Lake. Based on the basin＇s characteristics and actual situation of Bosten Lake, an ecosystem services evaluation system which involving 4 elements and 12 indexes was built. By using the multi-level gray correlation meth- od, researchers calculated the established evaluation system and got the ecosystem services grade of Bosten Lake from 2001 to 2012. The results show that the ecosystem services ranked the general grade and the average score is 67.60. The ecosystem services score was decreased first and then increased slowly in the past 12 years, so the Bosten Lake basin＇s ecological services should be further developed with practice.
