祁连山地湿地生态质量评价

Evaluation on Wetland Eco-environmental Quality of Qilian Mountains in Qinghai Province

基于遥感监测、样地与样线调查以及定点观测,研究青海省祁连山地湿地资源现状。基于Delphi专家咨询法和AHP分析法,评价了青海省祁连山地湿地生态质量状况。结果表明:青海省祁连山地湿地资源面积为94 054.73 hm2,分为4类6型,99.65%为自然湿地。湿地面积按类型分:沼泽湿地>河流湿地>人工湿地>湖泊湿地,按县域分:祁连县>门源县;青海省祁连山地门源县和祁连县湿地生态质量均为一般,总体上祁连山地湿地生态质量为一般。

Based on the remote sensing satellite monitoring, line transect and ample investigation methods and spot observation method, wetland resource of Qilian Mountains, Qinghai Province was studied. Meanwhile, based on the Delphi method and AHP analysis method, eco-environmental quality of wetland at Qilian Mountains was assessed. The results indicate that the total area of wetlands at Qilian Mountains of Qinghai Province is about 94054.73 hm2, divided into 4 classes, 6 types, 99.65 percent is nature- wetland. According to the classification, wetland area by type was followed decreasingly ranks as swamp wetland, river wetland, artificial wetland and lake wetland, wetland area by the county territory was fol- lowed decreasingly ranks as Qilian County, Menyuan County. The results also indicate that the eco-environmental quality of wetland at Menyuan County and Qilian County were average, to sum up, the eco-environmental quality of wetland at Qilian Mountains was normal.
