Influence of Reservoir on Groundwater Environment in the Ecologically Fragile Area, Northwest of China

As the research proposed reservoirs after impact on surrounding ecological fragile areas of groundwater level and scope, through reservoir area its data collecting, hydrogeology survey related test, for Modflow system simulation platform, to boundary conditions, initial conditions source sink term hydrogeological parameters, model identification verification, The parameters in study is constructed. results show that depth near will be higher than critical value (1.8 m) secondary salinization soil. At same time, according investigation experiment, if does not do seepage treatment, water infiltration aggravate environmental problems ecologically area.
