选取青海湖流域毗邻区7个气象站点,对1961—2010年的降水气候要素的变化趋势进行了分析,采用Mexhat小波方法对其进行了周期分析.为查明青海湖流域降水增加的水分来源方向,选取峰值阶段做青海湖流域内和青海湖流域毗邻区的降水变化进行相关分析.结果表明:研究区1961~2010年间年平均降水量均呈波动上升的趋势,其中毗邻区东南部的贵德和东北部的门源、北部的祁连降水量增幅较小,分别为0.5mm/10a、1.4mm/10a、6.8mm/10a,而西部的都兰和德令哈降水量增幅最大,降水量变化存在27a的主周期.青海湖流域降水增加与毗邻区降水变化的相关程度很高,相关性达到0.912,尤其南部兴海方位的降水变化对青海湖流域降水增加的关系最为密切,相关性达到了0.856.初步认为,青海湖流域降水量增加来自西南季风水汽源有关.

The paper chooses seven meteorological sites in Adjacent to the area of qinghai lake valley, analyzes Precipitation elements of these areas from 1961 to 2010 and adopts Mexhat wavelet method to car-ry out the cycle analysis. To find out the water source direction of Qinghai Lake basin,the research analy-zes precipitation changes Adjacent to the area of qinghai lake valley by choosing peak stage. The result show s that the annual average Precipitation during 1961~2010 is on the volatility rise:the southeastern part Gui De,the northeastern part Men Yuan and the northern part Qilian have a lower rainfall increase rates,which are 0.5mm/10a,1.4mm/10a and 6.8mm/10a;while the western part Du Lan and Delingha have a greater rainfall increase rate.,rainfall change is 27a major cycle. Qinghai lake basin precipitation in-crease and adjacent to the area have a high degree of precipitation is related,the correlation of 0.912,Espe-cially the southern part Xinghai's precipitation change has an obvious impact on Qinghai Lake basin precip-itation ;the correlation is 0.856. Preliminary thought, qinghai lake basin precipitation increases from southwest monsoon water vapor source.
