【摘要】：研究区位于海拉尔河谷平原上游地段,由海拉尔市东约20km处哈克镇向东北经扎罗木得、大雁镇、牙克石市至乌尔其汗镇。其东西长109km,南北宽87km,面积4243km2。本文通过水文地质测绘、水文物探、水文地质钻探及抽水试验、地下水动态监测、水土样的取样与分析等野外工作,大致查明了研究区内地下水的埋藏条件与分布规律,初步查明了地下水的补给、径流、排泄条件。同时,采用均衡法对研究区地下水资源进行了评价并对可开采资源量进行了计算。研究区内含水层主要由第四系上更新统和全新统圆砾及薄层砾砂、卵石组成,厚度在河谷中心一般10-30m,最厚37.29m,单井涌水量一般大于3000 m3/d,水化学类型多为HCO3-Ca、HCO3-Ca·Na^ HC、3-Na·Ca型水,矿化度一般小于0.5g/L。经计算,研究区内第四系松散岩类孔隙潜水储存量为79.047×108m3,多年平均天然补给量为15205.22×104m3/a,可开采资源量为9123.13×104 m3/a,即24.99×104 m3/d。海拉尔河单宽补给量为12381.49m3/d·km,即451.92×l04m3/a·km,免渡河单宽补给量为13080.17m3/d·km,即477.43×104m3/a·km。
[Abstract]:The research area is located in the upper reaches of the Hailar Valley, from Huck Town to the northeast via Zaromud, Dayan Town, Yakeshi City to Ulchikhan Town, from Hailar City to Dongyao 20km. It is 109km in length, 87km in width and 4243km2 in area. Based on the field work of hydrogeological mapping, hydrogeophysical exploration, hydrogeological drilling and pumping test, dynamic monitoring of groundwater, sampling and analysis of soil and water samples, the burial conditions and distribution of groundwater in the study area are found out in this paper. The recharge, runoff and discharge conditions of groundwater were preliminarily identified. At the same time, the equilibrium method is used to evaluate the groundwater resources and calculate the recoverable resources. The aquifer in the study area is mainly composed of the upper Pleistocene of the Quaternary and the new series of round gravel and thin layer gravel sand. The thickness of the aquifer is 10-30 m in the center of the valley, the thickest is 37.29 m, and the water inflow of single well is generally more than 3000 m3 / d, and the hydrochemical type is mostly HCO3-CaHCO3-Ca Na ^ HC3-Na Ca type water, The salinity is generally less than 0.5 g / L. The results show that the phreatic storage capacity of the Quaternary loose rocks is 79.047 脳 108m3, the annual average natural replenishment is 15205.22 脳 104m3 / a, and the recoverable resource is 9123.13 脳 104m3 / a, that is 24.99 脳 104m3 / d. The single width feed amount of Hairar River is 12381.49m3/d km, that is, 451.92 脳 l04m3/a km, and the single width feed amount of the river is 13080.17m3/d km, that is, 477.43 脳 104m3/a km.
