Investigation And Evaluation Of Ground Water Resources In Songyuan

With the rapid development of social economy and the acceleration of urbanization process,especially the industrial water,urban living water and ecological construction of water increased significantly,the contradiction between water shortage further intensified.As an important part of water resources,the rational development and utilization of groundwater is particularly important.In this paper,Songyuan as a research area,through the groundwater resources survey and evaluation,master it's the basic situation of groundwater resources.For the scientific management and effective development and utilization of groundwater resources to provide a scientific basis to ensure the sustainable development and utilization of water resources.In this paper,based on the understanding of the natural geography and socio-economic situation of Songyuan,comprehensively studies the terrain and topography,geology,hydrogeological environment,and the groundwater chemistry,the groundwater resources calculation and evaluation of groundwater quality are carried out.During the evaluation process,the groundwater resources planning report and the previous research results of the counties(cities,districts)of Songyuan are referred.Analyzed and summarized the data of the meteorological,hydrological and groundwater monitoring from 2001 to2014.Analyzed the period of the city's agricultural irrigation area,the actual exploitation of groundwater,the diverting surface water and other information,referred to the comprehensive planning of geological resources and calculation parameters of Jilin Province,and finally formed 35 years(1980~2014)series and 14 years(2001~2014)series of two Set of evaluation results.After analysis,the amount of groundwater resources in the whole area is 137084.6310~4m~3(35 years series)/133863.3310~4 m~3(14 years series).The total exploitable amount of groundwater is 104912.3310~4m~3(35 years series)/16061.4310~4m~3(14 years series).The development and utilization status of groundwater in Songyuan is analyzed,the potential of groundwater development is evaluated,and corresponding groundwater resources Protection measures and measures.Analysis shows that there are potential mining areas in the city except the Lalin River Basin,distribution area of about 20358.71km~2,accounting for 91.4%of the city area.
