摘　　要：为利用北门江建设用河砂资源,在收集前人资料的基础上,结合本流域特点开展岩层富水性、地表水分布、水化学类型、矿床充水因素等水文、工程及环境地质资料评价分析,表明流域区含水层(矿层)属强富水性孔隙潜水含水层,厚度较大,富水性强,地下水位埋深浅,矿层的顶部易崩塌,工程地质性质较差,上游来砂淤积量与开采量保持动态平衡时不会造成河床边坡失稳,根据分析评价结果提出建议,可作为流域相关地质,规划管理工作的参考。In order to utilize the river sand resources for the construction of Beimen River,based on the collection of previous data and combined with the characteristics of the basin,the evaluation and analysis of hydrological,engineering and environmental geological data,such as water-riched strata,surface water distribution,hydrochemical type and water-filling factors of the deposit were researched.The results show that the aquifer(mineral layer)in the basin was a water-riched pore aquifer with large thickness,strong water-riched and shallow groundwater level.The top of the mine layer is easy to collapse,and the engineering geological property is poor.The river bed slope will not be unstable when the silt accumulation in the upstream reaches a dynamic balance with the mining amount.According to the analysis and evaluation results,the suggestions are proposed,which can be used as a reference for the related geology and planning management of the basin.
