南昌市城区地下水动态特征及影响因素分析
|
摘要
利用南昌市区1983—2010年地下水位监测资料,结合地下水补、径、排条件,分析该区上部第四系孔隙水位的时空变化特征及其影响因素。结果显示南昌市区地下水位动态类型主要有两种:自然动态型和人为动态型,这两种动态类型的动态特征在时空分布上有明显差异。赣江附近及漏斗外围,地下水动态与河流水位及降雨量关系密切,随气象水文因素呈明显周期性变化;漏斗中心区域地下水动态受人为开采因素影响,随开采量变化呈明显的上升或下降趋势。
Based on the groundwater recharge and discharge conditions,the upper Quaternary pore water level change characteristics and the influencing factors were analyzed using monitoring data of groundwater level in Nanchang City from 1983 to 2010. The results show that the dynamic types of groundwater level in Nanchang City can be divided into two types: natural dynamic type and artificial dynamic type. There are significant differences in the spatial and temporal distribution of different types of groundwater level. The groundwater is closely related to river water level and rainfall near Ganjiang River and the periphery of the cone,having significant cyclical changes with meteorological and hydrological factors. Groundwater dynamics was affected by human factors in the cone center area,and the trend of rising or falling was obvious with the change of the mining quantity.
