Abstract

Based on the remote sensing satellite monitoring,line transect and sample investigation methods and spot observation method,the wetland resources at Yushu prefecture of the three-river source region in Qinghai Province were studied.Meanwhile,based on the Delphi and AHP analysis methods,eco-environmental quality of the wetlands at Yushu prefecture was assessed.The results indicate that the total area of the wetlands at Yushu prefecture of the three-river source region in Qinghai Province is about 2 634 425.03hm2,divided into 3 classes,8 types,all as natural-wetland.According to the classification,wetland composition proportion decreasingly ranks as swamp wetland,river wetland and lake wetland;at meantime,according to the county territory,decreasingly ranks as Zhiduo county,Qumalai county,Zaduo county,Chengduo county,Yushu city,Nangqian county.The results also indicate that the eco-environmental qualities of the wetlands at Zhiduo county,Qumalai county,Zaduo county and Chengduo county have achieved top rating,Yushu city and Nangqian county have achieved the average rating,to sum up,Yushu prefecture has achieved the fair average rating in netland eco-environment quality.

Key words： wetland resource; eco-environmental quality; evaluation; three-river source region; Yushu prefecture
