摘要
依据榆溪河流域水文地质条件构建水文地质概念模型,在此基础上基于可视化数值模拟软件建立流域三维地下水流数值模型,模型经识别与校验完成后,分别对流域地下水补给排泄量、地下水储量、可开采资源量进行计算评价,研究表明:(1)流域2006年、2009年和2010年在均衡期内地下水处于负均衡状态;2007年、2008年、2011年、2012年和2013年在均衡期内地下水处于正均衡状态。(2)区内第四系含水岩组地下水容积储存量为157.488×108m3,侏罗系含水岩组地下水弹性储存量为9.477×108m3。(3)全流域现状地下水开采率为16.40%,新增开采后总的地下水开采率为29.21%,属于较低~合理水平。
Based on the hydrogeological conditions of Yuxi River Basin Construction of hydro geological conceptual model,based on the simulation software to establish the three-dimensional basin groundwater flow numerical model based on the numerical model of the visualization,recognition and verification is completed,respectively for the basin groundwater recharge,groundwater storage and excretion of recoverable resources evaluation calculation. The results show that:( 1) in 2006,2009 and 2010,the inland water is in a negative equilibrium state; in 2007,2008,2011,2012 and 2013,during the equilibrium period,the inland water is in a positive equilibrium state.( 2) The volume storage of groundwater in the Quaternary aquifer group is 157. 488 × 108 m3,and the elastic storage of groundwater in the Jurassic aquifer group is 9. 477 × 108 m3.( 3) The exploitation rate of groundwater in the whole basin is 16. 40 %. After the new mining,the total groundwater exploitation rate is29. 21 %,which belongs to the low to reasonable level.
