摘  要：
遥感(RS)和地理信息系统(GIS)是我国大型湖泊、水库水体面积监测中不可或缺的重要手段。本研究在论述我国自主研发的环境减灾卫星CCD数据特征的基础上,利用多波段和单波段相结合的方法,构建了基于环境减灾卫星的水体识别模式,并根据该模式提取了青海湖自2008年9月以来至2011年每年4至11月期间的水体面积。结果表明,1)2008―2011年,青海湖面积呈持续增大趋势,且2008―2010年增幅较小,而2011年青海湖面积增幅显著;2)2009―2011年,青海湖面积呈现有规律的季节波动,但2011年各季节面积均高于前3年同期;3)2008―2010年青海湖自9月开始至封冻前,面积逐月减小,且2009―2010年青海湖面积均在9月达到最大值;2011年与前3年相比,青海湖面积除7月与2010年同期大致相当外,其余各月面积明显偏大,且湖面至10月才达到最大值;4)2008-2011年的10月,青海湖面积变化较明显的区域位于青海湖的东岸和西岸,湖岸线分别向东、向西推进了130～630和100～600m,东岸沙岛湖季节性与青海湖连通;5)青海湖面积持续增大的主要原因有3个方面,近年来青海湖流域气候呈现暖湿化趋势;青海湖周边河流的入湖径流量增加;青海湖周边人类生产活动趋缓。

摘  要：
Remote sensing(RS) and geographic information system(GIS) are essential important means of monitoring water body areas for large lakes and water reservoirs.Based on the characteristics of CCD data from self-development Environmental Mitigation Satellite and built an identification mode of water body by using the combination methods of multi-bands and single band.According to the mode,the water area of Qinghai Lake during April-November each year had been extracted from September 2008 to November 2011.The results showed that: 1) The Qinghai Lake area had a continuous increasing trend from 2008 to 2011,among which it had a smaller increase from 2008 to 2010,while there was a significant increase in 2011.2) From 2009 to 2011,the area of the Qinghai Lake of each season presented a regular wave.However,the area of each season in 2011 was higher than that in the same season of the previous three years.3) The water area reached to the maximum in every September from 2009 to 2010;and decreased monthly from September to the freeze season in 2008-2010.In 2011,compared to the previous three years,the maximum value emerged in October and the area in each month was significantly larger except the area in July was roughly equal to that in the same period of 2010.4) The obvious change areas of the Qinghai Lake mainly located in the east and west coasts in October from 2008 to 2011.Shorelines were put into eastward 130-630 m and westward 100-600 m,respectively.The sand island lake in the east coast was seasonally connected to the Qinghai Lake.5) The major reasons for Qinghai Lake area to increase continually were that in recent years,Qinghai Lake Basin climate showed a warm wet trend,the surrounding river runoff into the lake was increased and human production activities in the surrounding areas were slowed down.
