Groundwater Resources Evaluation Of Water Supply Source In Zhengzhou Airport

Groundwater is an important part of ecological system and the Important guaranteefor maintaining hydrologic cycle. With the rapid development of urbanization,industrialization and groundwater has become one of the important water supply source inour country. However, in the north of China where groundwater is used as the main watersource, the phenomenon of available water decreasing is more and more serious. This ismainly due to overexploitation and pollution of groundwater. Groundwater as ourlong-term use of fresh water resources, because of its own characteristic, must be usedscientific and reasonable, so we need to evaluate the groundwater resources before we useit.The airport is located in XueDian Town, the northwest of XinZheng City, takingXinZheng International Airport as the core, driving the development of relevant industriesof science, industry and trade, logistics distribution, the coordinated development of strongeconomic area. With the rapid development of aviation port, a large number of well-knownproductive enterprises have settled in here, so the industrial, domestic water supplycapability has become the urgent need.This article provides scientific basis for the construction of water supply sourceexploitation, by systematically analyzed in the study area about the geological andhydrogeological conditions, make sure the hydrogeological condition, master in recharge,runoff, drainage condition and its dynamic variation of water supply range of middle-deepgroundwater, establish groundwater evaluation mathematical model, evaluate the miningquantity allowed by the two-dimensional finite element method and the analytical methodof groundwater, general industrial and drinking water quality in middle-deep groundwater,and forecast all kinds of environmental geological problems that may arise after mined andchange trend of groundwater level during mining period.Through Visual Modflow software simulating the drawdown of groundwater, andusing numerical method and analytical method to evaluate groundwater resources,predicting it under different mining conditions in the future. The results show that at theairport to the north at18000m3/d mining, can meet the production requirements of5years,but the exploitation quantity30000m3/d not, and in the airport planning area, yield is15000m3/d, which can meet the requirements of mining for20years.
