| 摘 要： | 湖水位下降是近期我国西北地区湖泊一种普遍现象，由于该地区湖泊多属闭合流域，湖泊水位下降往往导致湖水浓缩咸化，进而给湖体及湖周带来一系列的生态环境问题，本文根据近几十年来岱海的湖区气候，湖泊集水域的入湖径流特征分析，以及湖泊水量平衡计算，分辨出１９５５－１９９５年３．８５ｍ，的水位降幅中，人为影响的贡献为３．１７ｍ，占８２％，自然因素的贡献为０．６８ｍ，占１８％，说明岱海湖水位下降主要是集水域内人类

| Abstract: | It is widely accepted that the lake water level will descend in the northwest of China in the near future. Because most of lakes in northwestern China belong to closed basins, the descent of water level often results the condensation and salination of the water, bringing about a series of environmental problems to the lakes and the catchment areas. A calculation based on the analysis of climate, runoff, water balance and water level in Daihai Lake basin shows that the total falldown of water level is 3. 85 m during 1955 to 1995, among which human factor occupies a drop of 3. 17 m. It is very clear that human activities give very strong impact on the water balance of Daihai Lake. |
