中文摘要:

      以Landsat卫星1972~2013年间5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5个时期盐湖面积变化的图谱。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内盐湖面积变化的影响机制,探讨不同气象因子对盆地内盐湖面积变化的作用。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,且平均气温的作用占主导性,这为库木库勒盆地盐湖的演化研究以及盐湖资源开发提供了相应参考和借鉴材料。

英文摘要:

      :Boundary information of saline lake water was extracted,and combined with the field investigation and indoor interpretation analysis,with RS and GIS technology based on the remote sensing image data of five periods of Landsat in 1972~2013,the variation diagram of the changes of Saline Lake area during the five periods were drawn.In addition,the response relationship of saline lake area combined with the meteorological (precipitation, average temperature, relative humidity, average wind speed)of Kumukule Basin was analyzed, 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:the 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 saline lake resources exploration in Kumukule Basin.
