摘要
Abstract
This paper analyzed the chanfes of Qinfhai Lake durinf the period of 1956-2011 from three aspects:water level,water surface area and lake shoreline. The results show that the water level dropps about 3. 28m in these 56 years,while raises 1. 01m from durinf the period of 2005 to 2011;lake surface area and lake water level have a food positive correlation accordinf to the landsat imafe data analysis;the lake surface area has reduced 397. 5km2 from 1956 to 2004 and expanded 80. 4 km2 from 2005-2011;the Shadao Lake has isolated from the main lake body since 1995,and lake shoreline chanfes unevenly;the main influence factor for water level chanfe is the chanfe of rainfall and runoff,while the other factors includinf temperature,evaporation,flacier melt water and human activities are not dominant factors.关键词
