In recent years, with the deterioration of the Ebinur Lake area, the increasingly serious environmental problems occurred. Study on the Ebinur Lake area change for the protection of the ecological environment in Ebinur Lake area, the ecology of social and economic development, and even the entire northern region of Xinjiang Uygur Autonomous Region plays the significant role. Using the monthly high resolution remote sensing image information source from 2008 to 2015, extraction of lake boundary normalized coordinate system and projection methods and using GIS as a tool, the change information of the surface of the lake was obtained. Ebinur Lake boundary from March to October in 2013 was extracted, the dynamic change of lake superposition boundary was to analyzed. Combining with the Bole City Bureau of hydrology and water resources data of 1989—2007 of the Ebinur Lake area, we analyze the interannual variation. We also used the annual runoff data of Bortala River and Jinghe, data of precipitation, average temperature data statistics to analyze the runoff characteristics of the Jinghe, Bole River, to study the influence of tributary of the runoff variation of runoff in the Ebinur Lake area. The results showed that: (1) dynamic lake utilization degrees of the Ebinur Lake area were analyzed, the part of the years had increased, but the overall presented decrease trend; (2) taking 2013 as the example, the dynamic changes of the Ebinur Lake from March to October were monitored, it was found that Ebinur Lake area continued to decline from March, in October the lake area was the smallest, and most of the water change occurred in the northwestern part; (3) taking water inflow of Ebinur Lake and lake area for statistical analysis, these two parameters have the good correlation, and the correlation coefficient is 0.71.
