中文摘要：

通过多次野外调查,利用遥感影像数据,在＂3S＂技术支撑下,划分了青海湖流域天峻县各景观类型并计算出了面积。在此基础上,使用生态系统服务价值法和区域景观价值法确定了天峻县各生态类型生态补偿的上下限标准。结果表明：草地的生态服务价值最为显著,为66.97×108元,生态系统服务价值最小的景观类型为灌丛,其价值为1.19×108元;从景观类型面积看,天峻县高寒草甸面积最大,达到717572.16hm2,石砾地面积最小,仅为205.93hm2;在不同类型植被景观价值中,高寒草甸对青海湖流域天峻县景观价值的贡献最大,为35.33×108元,山地灌木林景观价值最小,仅为0.08×108元。天峻县生态补偿的理论上限为101.42×108元/年,补偿理论下限为47.61×108元/年。

英文摘要：

Based on several field investigations ,remote sensing image data and ＆quot;3S＆quot; technology ,this article has marked off various landscape types of Tianjun County and has calculated its area ,on this basis ,this article determined the eco -compensation＇s top and bottom limits of each ecological types in this area through the ecosystem service value method and regional landscape value method .T he result has show n that ecological service value of grassland ,which is the most obvious ,is 6 ,697 billion RMB .The lowest ecological service value of landscape type is bush wood whose value is 119 million RMB ;from the perspective of landscape type＇s area ,alpine meadow occupies the largest area in Tianjun county ,w hich reaches 717572 .16hm2 ,w hile the gravel＇s area is the smallest ,which is only about 205 .93hm2 .Meanwhile ,among the different landscape types＇ecosystem service value ,alpine meadow contributes the most to Tianjun county＇s landscape value in Qinghai Lake watershed ,which is about 3 .533 billion RMB ,while the minimum value is brush ,which is just about 8 million RMB .The top limit of eco -compensation for Tianjun county is 10 ,142 billion RMB/a and the bottom limit is 4 ,761 RMB/a .
