| 摘 要： | 利用Landsat卫星1972-2013年间五个时期的遥感影像数据为基础，结合野外实际调查和室内解译分析，运用RS和GIS技术，提取影像中盐湖湖水边界信息，并绘制了五个时期盐湖面积变化的图谱。并结合库木库勒盆地气象数据（年降水量、平均气温、相对湿度、平均风速）对盐湖面积变化进行响应分析，探究盐湖变化与气候之间的相关性，并讨论气候变化对库木库勒盆地地区内盐湖面积变化的影响机制，分析不同气象因子对盆地内盐湖面积变化的作用。得出平均气温、降水量、相对湿度对盆地内盐湖的面积扩大均有促进作用，而且平均气温的作用占主导性的，这为库木库勒盆地盐湖的演化以及盐湖资源开发提供相应参考和借鉴意义。

| Abstract: | Boundary information of Saline Lake water in the image was extracted, and combined with the field investigation and indoor interpretation analysis, using RS and GIS technology based on the remote sensing image data of five periods of Landsat in 1972-2013, and drawing the map of the changes of Saline Lake area during the five periods. In addition, analyzing the Response relationship of Saline Lake area combined with the meteorological (precipitation, average temperature, relative humidity, average wind speed) of Kumukule Basin, to explore the correlation between Saline Lake and climate change, and discuss the influence mechanism of climate change on the Saline Lake area, analysis on the effect of different meteorological factors on the area change of Saline Lake basin. The results show that: Average temperature, precipitation and relative humidity can promote the Saline Lake Area broadening on the basin, and the role of average temperature is dominant. The results provide reference for the evolution of Saline Lake and the resources development Saline Lake of Kumukule Basin. |
