西北内陆地区戈壁沙漠面积82.47万平方公里,占我国戈壁沙漠面积的90%。因此,研究戈壁沙漠地下水及其合理开发利用,对解决沙区人畜饮水、经济规划、国防建设和治理沙漠具有重要意义。最近四、五年,我们开展了腾格里大沙漠西南缘的地下水动态观测工作。本文就观测研究成果进行 The Gobi Desert in the northwest inland area covers an area of ​​822,700 square kilometers, accounting for 90% of the total area of ​​the Gobi Desert in our country. Therefore, studying the Gobi desert groundwater and its rational development and utilization are of great significance to solving the problem of human and livestock drinking water, economic planning, national defense construction and desert control in the desert area. In the recent four or five years, we have carried out groundwater dynamic observation in the southwestern margin of the Tengger Desert. This article observes the research results
