摘要: 近几十年来,青海湖水位不断下降.人为活动耗水虽对青海湖水位下降有一定影响,但不是主导因素.其主导因素为湖区气候决定的湖水水量收支平衡状况.青海湖面的蒸发耗水占湖区的总耗水量92%以上,年湖面蒸发量约为年降水量的2~3倍.

Abstract: Qinghai Lake is the largest inland lake in China. It is a closed-drainage lake located at about 3194m above sea level in an active tectonic basin in the northeastern Qinghai-Xizang Plateau. The lake area was about 4 304. 5km2 in 1986.The human activities around Qinghai Lake from 1949 to 1987 and the change of the lake level from 1959 to 1987 are discussed in detail in this paper. By comparing and ana-lyzing relationship between descending of Qinghai Lake level and the human activities around the lake,we found that descending of Qinghai Lake level was mainly caused by the climatic change in this region,not by the human activities around the lake.
