Analysis And Evaluation Of Groundwater Resources In Xinghe Logistics Park Of Ulanqab City,Inner Mongolia

Water is the source of life.As an important natural resource,water is a necessary condition for human survival and development.Water resource is an important factor to promote social and economic development and civilization progress.The arid and semi-arid areas in northern China have always been the main sources of drinking water and farmland irrigation relying on groundwater.However,urban groundwater exploitation intensity in northern China is generally higher,and most areas,especially large and medium-sized cities,are in the state of overexploitation or serious overexploitation.The rational exploitation and utilization of groundwater becomes particularly important.The research area of this paper is the logistics park of xinghe county,ulanqabu city.By analyzing the hydrogeological conditions of its quaternary,neogene and paleogene aquifers,the groundwater resources of its quaternary,neogene and paleogene are evaluated,and reasonable groundwater development,utilization and protection measures are proposed.The research area is 400km2.Paper through the analysis of hydrological geology,hydrogeology drilling,pumping test,the ground of surveying and mapping electrical sounding and hydrological logging,water,soil(rock)sample testing,methods of comprehensive research,analysis of the aquifer lithology,thickness,water content,permeability,water quality,water quantity change rule and recharge,runoff and discharge conditions,such as analysis of framed the relatively abundant water quantity,respectively by the method of equilibrium method and the interference well group,through the calculation of the groundwater resource through the water samples analysis of experimental data the water quality quality,comprehensive evaluation.Main achievements:Volume status in natural recharge groundwater in the study area is1516.31x10~4m~3/a,for many years an average of 1070.28x10~4m~3/a,years average allows the groundwater resources is 731.28x10~4m~3/a,quaternary diving years average allows the production of 386.09 x 10~4m~3/a,confined water for many years an average allows the production of 345.19x10~4m~3/a(among them,the status quo of production53.19x10~4m~3/a,water source of new mining resources allow 292.00x10~4m~3/a),Finally it is concluded that the groundwater in the study area still has certain exploitation potential.Research in the vast majority of groundwater?for diving,?,?class water,good water quality.The vast majority of the confined water belongs to?,?water,water quality is good,suitable for drinking.Only part of the indicators such as cadmium,chromium,total hardness,sulfate,nitrite and other excessive,need to be properly handled,before drinking.Through analysis and evaluation of groundwater resources,the proposed water source area is finally given,which is about 31.22km~2.According to the hydrogeological conditions of the water source to be selected,the water inflow of a single well during mining can be measured by 2000m~3/d,the distance of a well is 500m,and the single or double rows of Wells can be distributed,and 4 Wells can be distributed.
