通辽地区地下水系统的辨识与分析

IDENTIFICATION AND ANALYSIS OF UNDERGROUND SYSTEM OF TONG LIAO AREA

本文利用地下水系统的内外部信息对通辽地区地下水系统进行了辨识与分析。结果认为 ,通辽地区含水层系统可概化为 3层非均质各向异性的统一潜水层组。但根据研究问题的时空尺度不同 ,在大时空尺度上进行水资源评价和管理时 ,鉴于含水层厚度相比水平距离来讲很微小 ,故可进一步概化为非均质各向同性的统一潜水层组 ;该地下水系统以垂向水交替为主 ,水平径流微弱 ;地下水系统的东边界为可预测的已知水头边界 ,南边界为随季节性变化的已知水头边界 ,西边界为可预测的已知水头边界或已知流量边界 ,北边界为流线边界 (隔水边界 )

The underground water system of the Tong Liao area is identified and analyzed using the internal and outside information of the underground water system. The conclusion is drawn as bellow: Tong liao area is a three layers nonhomogeneous and anisotropic unified phreatic aquifer group. however,according to the scale of study,When evaluating and managing the ground water resources in large scale,the system can be idealize as a nonhomgeneous and isotopic unified phreatic aquifer group; The water flow in mainly in vertical direction and very slowly in horizontal direction in the underground water system; The eastside of the underground water system is water head bound which can be predicated,the south side is water head bound that varied with seasons,the western is water head bound which can be predicated or the discharge has been known,the northern bound is flow line bound impermeable.
