摘　　要：近几十年青藏高原东北侧各河流、湖泊的观测记录表明,其水文情势正在向干暖化方向发展。本文利用近几十年来青海湖、达布逊湖及其周围的有关水文气象资料和东昆仑山区地震资料,从地-气相互作用的观点出发,对它们的关系作了初步分析。结果表明:1.东昆仑山区地震与青藏高原东北侧青海湖、达布逊湖的水位有十分密切的关系。2.东昆仑山区地震与地球自转速度的变化、El Nino 的发生有很好的配合。3.对照水位变化与太阳黑子的变化可见,近几十年来,水位下降的最大时段均出现在两次 El Nino 间隔6年的时段中,而上升的最大时段,正好处于太阳黑子的双周上升段。据此初步预测在未来的十年左右,水位仍将呈波动式下降,但幅度将比过去小。Based on the viewpoint of earth-atmosphere interaction,the hydro-meteorological data of Qinhai lake.Dabuxun lake and earthquake data in east Kunlun mountain were analyzed.Some conclusions were obtained as follows: 1)There were close relation between earthquakes in east Kunlun mountain and lake level of Qinhai lake and Dabuxun lake. 2)There were good correspondence among earthquakes in east Kunlun mountain,the change of earth rotation and EI Nino event except in 1965 and 1969. 3)Comparing the change of lake level and the change of sunspot,it can be found that the lake level descending maximums were in the 6 years period of the interval of two EI Nino events: and the lake level ascending maximums were in the rising period of biweekly sunspot cycle.Based on the relation of lake level and earthquake,it is predicted that the lake level will be descending wavily,but the magnitude will be smaller than that before in next decade or so.
