典型农业活动区浅层地下水地球化学特征及成因分析
Shallow Groundwater Geochemical Characteristics and Formation in Typical Agricultural Activity Area
摘要
Abstract
Ten indexes of shallow groundwater in Changzhou including HCO3- , Cl-, SO42- , F- , Na+ , K+ , were detected with field survey and laboratory analysis, and the quality, geochemical trait and formation mechanism of shallow groundwater were analyzed. The total hardness of 2 samples of the poor phreatic water in loosening rocks of quaternary period, 1 sample of micro confined water, 1 sample of the first confined water exceed the standard. The main chemical types of shallow groundwater in Changzhou are HCO3 -Ca ·Na ( Na·Ca) and HCO3 -Ca·Mg. There are different chemical types of shallow groundwater in the several areas of the southeast and west of Changzhou, which coincide with the flat topography and weak runoff of groundwater. There is a certain distribution regularity of various ions in the poor phreatic water, micro confined water and the first confined, and the distribution regularities in different aquifers are different. The chemical types of shallow groundwater are mainly correlated with the exchange adsorption effect of ions, the activities of human production and life and acid-base of shallow ground water.关键词
