呼和浩特盆地地下水演化特征研究
Study on Evolution Characteristics of Groundwater in Hohhot Basin
摘要
Abstract
This paper used the dynamic data of groundwater level and water quality in the typical section from the piedmont to the central plain in 1985 to 2015 to analyze the evolution characteristics of groundwater level dynamic and hydro geochemistry in different physiognomy cells. The results show that in the last 30 years,the groundwater level has continued to decline in the study area,and the TDS of groundwater shows an increasing trend.Moreover the difference of hydro chemical type between shallow groundwater and confined groundwater in the inter-action area of alluvial fan and plain gradually increases,but gradually decreases in the middle of the plain. From 2005 to 2015,the concen-tration intensity of groundwater in the plain area was rapidly increased and the strength of lateral recharge has switched into a fast decreasing pattern. Before 2005,the redox condition of shallow groundwater showed a tendency toward oxidation and then to a trend toward reduction, while the redox condition of confined water was basically stable.关键词
