Quality Evaluation and Formation Causes of Shallow Groundwater in the Plain Area of the Kaikai River Basin
摘要
Abstract
In order to evaluate the quality of shallow groundwater in the plain area of the Kaikai River Basin,the quality evaluation was carried out on 40 groups of shallow groundwater samples in the plain area of the Kaikai River Basin,and the hydrogeological conditions,the correlation of ion contents,and the ion proportion coefficients in the study area were analyzed.The results show that the groundwater in the areas close to the river in the west and north of the Yanqi Basin mainly receives the infiltration recharge from the river canal sys-tem.Due to the low salinity of surface water,the salinity of groundwater is also low.The recharge source of the groundwater far away from the river is lateral runoff,which belongs to the rock weathering type.Due to the main effect of leaching,bicarbonate water with low salin-ity is formed,and the water quality is good.The groundwater in the plain of the southwest side of Bosten Lake and the Peacock River Ba-sin belongs to the evaporation concentration type.Due to the slow flow velocity of groundwater and the shallow burial depth of the water table,sulfate and chloride water with high salinity is formed under the concentration effect,and the overall water quality is not optimistic.关键词
