本文在沿塔里木沙漠公路设置的监测井中,利用日本Alec Electronics公司生产的MODEL GFD4型地下水流向流速计,对塔克拉玛干沙漠腹地的地下水流速流向作了一次测定,结果显示:沙漠公路沿线地下水平均流速为:0.01 cm/min,即52.56m/a;地下水流动方向在沙漠北部主要以ENE方向为主,沙漠中部除个别井点外主要以EN方向为主,沙漠南部尼雅河下游监测井中流向由ENN方向和WNN方向构成,牙通古斯河下游观测井处以ESS方向为主。地下水流动方向的控制因素主要有:盆地总体地形因素、河流流量变化、局部地形因素。
Based on the MODEL GFD4 groundwater flowmeter produced by Alec Electronics Company in Japan, the velocity of groundwater flow in the hinterland of Taklimakan Desert was measured in a monitoring well along the Tarim Desert Highway. The results show that the average groundwater velocity along the desert highway is: 0.01 cm / min, ie 52.56 m / a. The groundwater flow direction is mainly in the north of the desert mainly in the ENE direction. The central part of the desert is mainly in the EN direction except for individual well points. The flow direction in the downstream of the Niya River in the desert is controlled by ENN And WNN direction. The observation well at the lower reaches of the Toothon River is dominated by ESS. The main control factors of groundwater flow direction are: the overall topographical factors of the basin, the change of river flow, and the local topographical factors.
