Abstract


The Jingbian located in four provinces of Shaanxi, Gansu , Ningxia, Inner Mongolia border , is an important part of the national energy and heavy chemical Yulin base . In recent years , the rapid development of the regional economy , the sharp increase in water demand , has resulted in some sections of the water tables are falling , and the disappearance of lakes in the local Saudi activation and other negative effects of the ecological environment . Research PUMPING interaction , and environmental effects of groundwater development , groundwater water sources rational development and eco- environmental protection and regional development of the national economy has important practical significance . Research on the development status of water sources in the study area , the analysis of the groundwater resource development trends and the effects on the environment ; analysis through the study of the development of the history of the study area , water resources development over evolution Cheng Zhongquan set River , Hazel , and groundwater levels provide the basis for the quantitative study of water resources development and its environmental impact . Through the study of the hydrogeological analysis methods and the groundwater flow system , the establishment of a conceptual model and mathematical model of the hydrogeology of the study area , the groundwater flow numerical simulation software ProcessingModflow Pro numerical analysis , identify groundwater flow simulation model based on large-scale pumping test data parity. Basis for the establishment of a three - dimensional groundwater flow numerical model , the exploitation of water sources mining plan dynamic predictive analysis and research the PUMPING different ways , as well as the impact on the surrounding environment , to determine the degree of the rational development of water sources and allowable withdrawal . The 50-year water resources study area using historical analysis , the first inverse modeling Haizi evolution in the region . Rewet test as well as covering conditions based on field analysis , numerical simulation , and palm high rabbit Haizi diversion covering technology and its environmental impact effects were studied . Study area groundwater numerical simulation of three-dimensional flow model to study the trends of the different way of exploitation of water sources as well as the exploitation of water sources on the surrounding environment and Haizi years of evolutionary history of research on wind beach groundwater resources exploitation and ecological environmental Protection has practical value , accumulated experience and provide a reference model for the coordinated development of the arid and semiarid zones regional socio-economic and water resources and ecological environment .
