  1. Lakes and rivers are the most important water resources in XinJiang,since there are little precipitation and melted-snow water from high mountains,which are limited in summer season.The characteristics of water resources and the cause of these changes was analyzed in this research. The characteristics of water resources in XinJiang Uyghur Autonomous Region,China, using GIS and remote sensing Dilnur Aji 1,Akihiko Kondoh 2 1Graduate School of Science and Technology,Chiba University 2Center for Environmental Remote Sensing,Chiba University Study area Introduction Objectives .To detect the water area fluctuation of main lakes .To explore the rivers outflow change in the last 50 years .To analyze the main factors that governing water resources Results:Water area of lakes Used Data andMethodology D A B C D Rivers outflow There were 65% of decreased rivers and 35% of increased rivers between the period of 1956~1986. Most of the decreasing processes were happened in north XinJiang, and most of the increasing processes were happened in south XinJiang in that period. On the contrary, there was a significant change, which has occurred during the period of 1987~2000 when the outflow of the 77% rivers have doubled, and the slight of outflow of the 23% rivers have decline. Remarkable increase was in north XinJiang and a slight decrease was in south XinJiang during this period. 1987~2000 1956~1986 Socio-economic factors Climatic factors (1991~2000)-(1951~1990) Precipitation differencing Temperature differencing
