Evaluation of groundwater resources and analysis of related geological environment problems in Inner Mongolia Inland River Basin
This paper is the result of the evaluation of groundwater resources and analysis of geological environment problems.[Objective]In order to improve the understanding of hydrogeology and groundwater resources in Inner Mongolia inland river basin,improve the utilization efficiency of groundwater resources and reduce the geological environment problems.[Methods]Taking In-ner Mongolia Inland River Basin as the main work area,this paper identified the drainage characteristics and hydrogeological condi-tions of the basin,collected and sorted out the meteorological and groundwater development and utilization data of the basin in the past 20 years,updated the hydrogeological parameters related to groundwater resource evaluation,and summarized and analyzed the drainage items of groundwater resources in the basin.The drainage method and recharge method were used to evaluate groundwater resources in hilly and plain areas.At the same time,the characteristics of groundwater dynamic change in the basin are discussed comprehensively,and the ecological and geological environment problems related to groundwater such as lake shrinking and land de-sertification are discussed.[Results]It is calculated that the total groundwater resources in the inland river basin are 3.794 billion m3.The shallow groundwater level in the upper Bashang area generally experiences a general trend of first rising and then decreas-ing,and the groundwater level generally presents a cyclical trend during the year.Affected by the groundwater level,the lakes in the basin shrink seriously,the sandy desertification area decreases,and the saline-alkali desertification gradually increases.[Conclusions]This study provides basic data and scientific basis for sustainable development and utilization of water resources and ecological envi-ronment protection in this area.
