摘要:
以位于新疆西部的艾比湖为例综合利用地形图和遥感图像信息源提取湖泊边界归一化坐标系和投影方式,并以GIS工具进行湖面的叠加分析获取湖面变化信息.同时根据影响内陆湖泊水量的主要因素入手分析了艾比湖面积变化的原因找出影响湖面变化的主要因素探讨分析了湖泊生态环境建设的发展趋势.

Abstract:
It took a long time for regular survey in the change of water surface, and sometimes almost impossible in some areas of the plateau. With the development of earth observation and geography information science, the use of remote sensing techniques is at present the primary, and in many places the only, means of measurement. At the same time, GIS provides an efficient tool to analyze the status and the changes of lake. In this study, for the example of Ebinur lake lies in the west of Xinjiang, we use 1950-2000 serial map, photo and TM Landsat data, to coregistrate all images and construct lake border maps in GIS, then use the function of overlay analysis in GIS to measure lake area changes. The result shows that there were several fluctuations of water level in the past 50 years. Moreover, we put forward some analysis on the main reasons to influence the level.
Key words:  RS GIS Ebinur Lake  water level change
