摘要
塔克拉玛干沙漠降水不仅直接补给地下水，在粘土平地每年都要产生一定数量的地表径流通过集水网补给地下水，试验观测这两种形式的补给来源，将进一步加深对沙漠腹地下水蓄量分布情况的认识。
As the primary fresh water sources,local precipitation in the heartland of Taklimakan Desert,not only forms the runoff on the clayed ground,but also feeds the ground water.After the analysis of history records of the rainfall and the formation of clay sediments,the precipitation infiltration and runoff recharging experiment was conducted,a nature rainfall-runoff process was observed and recorded.The paper reveals that in the center of the desert an event of storm over 4mm may be occured on the clay ground.Thus,rainstorms and runoffs as main fresh water sources feed the groundwater directly.
