The main soil-groundwater environmental problems and influencing factors in northern Haihe plain, China

Taking soil and unconfined groundwater as a interreaction system, soil acidification and groundwater alkalinization and wetland degradation were analyzed in study area in this paper. The influencing factors of soil and unconfined groundwater environment were analyzed. Based on the realtest date of soil profiles and groundwater monitoring date, the research results were educed that soil environment was controlled mainly by natural factor, but the influence of human activity could not be ignored; unconfined groundwater environment was controlled by natural factor and human activity. The conclusion is very important for protecting soil and groundwater environment.
