摘    要:湖泊湿地生态系统是陆地生态系统的重要组成部分,适宜的水文条件保障着湖泊湿地生态系统的健康。本文以博斯腾湖小湖湿地为例,依据能值理论系统地计算湖泊湿地各项生态系统服务价值量,并运用相关分析、层次聚类分析等方法结合生态系统服务计算结果与四项关键水文参数,综合确定研究区适宜的生态需水范围。研究结果表明,博斯腾湖小湖湿地生态系统服务价值总量由2013年以前的上下波动(平均年增幅-0.2%,其中有7年为负增长)转变为2013年后的持续增加状态(连续6年增加,平均年增幅6%);区域来水量则经历了2000-2003年的丰水期、2005-2013年的枯水期以及2013年以来的水量持续增加等三个阶段;生态需水核算结果建议博斯腾湖小湖湿地应保证一年之内日均流量低于8.3 m^3/s的天数不超过72天,而一年之中日均流量超过20.8 m^3/s的天数不低于80天,湿地生态需水量在8.0-8.7 10^8m^3/a之间,最适宜生态水位范围为1047.4-1047.6m。本研究利用生态系统服务价值核算了湖泊湿地生态需水,对区域水资源调控提供了积极的参考价值。

Abstract:Lake Wetland ecosystem is an essential part of the terrestrial ecosystem, and suitable hydrological conditions are key factors to the health of the Lake Wetland. Taking the small lake wetland of Bosten Lake as an example, the ecosystem services of the lake wetland were assessed systematically according to the Emergy Theory. And then, combining with 4 hydrological parameters, the ecological water requirements range of the study area was determined by using correlation analysis and hierarchical cluster analysis. The results indicate that, the total value of ecosystem services had undergone a great change from the constant fluctuation before 2013 to the continuous increase after 2013; the regional hydrological conditions had experienced three periods, i.e., wet years from 2000 to 2003, dry years from 2005 to 2013 and runoff escalation years from 2013. Finally, 4 reference ranges of hydrological parameters related to ecological water requirements were calculated: days with average daily flow less than 8.3 m^3/s in one year should not exceed 72 days, while days with average daily flow more than 20.8 m^3/s in one year should not be less than 80 days, the ecological water requirements of the wetland is between 8.0-8.7 10^8 m^3/a, and the optimal ecological water level range is between 1047.4-1047.6 m. This study provide scientific guides for the regulation of the lake wetland ecological water requirements.
Keywords:Boston Lake  Lake Wetland  ecosystem services  ecological water requirements
