| 摘 要： | 利用2002～2017年MODIS数据，结合3个气象站观测资料，分析扎日南木错2002～2017年湖面变化以及气象要素之间相关性。分析表明；近15年来扎日南木错湖泊水域面积整体呈波动上升趋势，从空间分布来看，扎日南木错的西部和北部湖面扩张的比较明显，尤其是北部有个小岛，可以看到从小岛形成到消失过程。气温整体呈上升趋势，降水量和蒸发量呈下降趋势，湖泊水域面积变化与气温呈正相关，蒸发量和降水量呈负相关。

| Abstract: | Based on the Moderate Resolution Imaging Spectroradiometer (MODIS) data as well as observational data from three meteorological station, this study analyzes the lake area variation of Tharinamtso during 2002~2017 and the relationship with meteorological elements. The results show that the lake area of Tharinamtso demonstrates an increase trend during 16 years. Spatially, the western and northern area of Tharinamtso increase obviously, especially an isle in the northern area which formed and then disappeared. The temperature shows an increase trend, while the precipitation and evaporation shows a decrease trend. The lake area is positive correlation with the temperature, and negative correlation with the precipitation and evaporation. |
