The Responses Of Tibetan Plateau Lakes To The Climate Change

Over the past century, as the human civilization, industrialization, population growth, non-renewable resources consumption and the rapid development of economy, series of the human activities cause the climate apparent change.The Tibetan plateaus, called"the roof of the world".It have numerous lakes and rivers.In recent years,under the background of climate change, it happened the glaciers melting, lakes shrinking, temperature rising and rainfall reducing.The environment change of the Tibetan plateaus sensitively response to the climate change.In order to explore the feasibility of using earth observation to monitor lakes in Tibetan plateaus, this article choose the Lake Manasarowar and Rakas Tal as a typical experiment area.Satellite altimetry, remote sensing and GIS technology are used to research the elevation, area, glacier area, temperature and the rainfall changes in past thirty years. It makes a series of conclusion and analyzes the relationship between the lakes change and the climate change.The main results of this research are as follow:(1) From 2003 to 2008, the elevation changes of the lake Manasarowar.(2) From 1992 to 2002, the elevation changes of the lake Rakas Tal.(3) September 28, 2010, using GPS measured the elevation of the twin lakes.(4) From 1972 to 2010, the area changes of the lake Manasarowar and Rakas Tal.(5) From 1976 to 2010, the area changes of the Mount Kailash and Gurla Mandhata.(6) From 1995 to 2007, the temperature changes and rainfall changes of the Pulan County.(7) Summarized the main reason of the twin lakes changes.
