| 摘 要： | 分别利用2000年、2005年和2010年3期丰水期(7-10月)的TM影像数据,同时结合气象台站观测数据和地面调查资料,依据青海湖流域湿地分类体系,采用湿地类型转移矩阵等方法,分析近10a青海湖流域湿地的动态变化情况.结果显示,青海湖流域湿地约占流域总面积的23.99％,10 a来湿地总体比较稳定,总面积变化不大,而湿地类型之间的变化较明显,主要是永久性咸水湖、永久性河流、内陆盐沼、洪泛区平原和沼泽化草甸之间的变化.

| Abstract: | To find out the changes of the Qinghai Lake wetlands during the past 10 years,we used wetlands transfer matrix,analysed three landsat TM images(2000,2005 and 2010,high flow period),meteorological observation data and ground survey information,according to Qinghai Lake wetlands classification system.As a result,we got that wetlands area accounted for about 23.99% of the total area of basin,the wetlands were relatively stable during the past 10 a,the wetlands area had little change,while the wetlands types,including permanent lagoon,inland salt marsh,flood storage plain and swamp meadow,had an obvious transformation between themselves. |
