| 摘 要： | 在第二松花江傍河开采适宜性评价的基础上，根据研究区的地质和水文地质条件，建立了水文地质概念模型及相应的数学模型，建立了基于Visual MODFlow的地下水流数值模型；以地下水水位降深不大于含水砂层厚度的1/3为准则，通过使预测流场与允许降深条件下的流场尽量接近，给出了第二松花江干流傍河开采条件下的地下水允许开采量。结果表明:现状年条件下区域地下水资源开采强度较小，而傍河开采条件下各适宜区地下水开采潜力巨大，在多年平均降水保证率条件下，地下水允许开采量可达140×104 m3/d；适度规模傍河开采可引起地表水与地下水转化关系的变化，但不会对河流生态功能产生不利影响。

| Abstract: | Based on the evaluation of the suitability for river bank infiltration along the Second Songhuajiang River and the basic geologic and hydrogeological conditions of the study area, the hydrogeological conceptual model and the corresponding mathematical model are established, and the numerical model of groundwater flow based on Visual MODFLOW is formulated. The drawdown of groundwater level of 1/3 of less than the aquifer thickness is taken as the criterion. By making the predicted groundwater flow field as close as possible to the flow field under the conditions of the permissible drawdown, the allowable exploitation quantity of groundwater under the condition of RBF along the Second Songhua River is obtained. The results show that under the conditions of the current year, the exploitation intensity of groundwater resources is small. However, under the condition of exploitation near the river, the groundwater exploitation potential of each suitable area is as high as 140×104 m3/d, and the allowable exploitation of groundwater is large under the annual precipitation frequency. The interaction of groundwater-surface water will be influenced, but there will be no side effects on the ecological function of the river. |
