海河平原北部地区主要水土环境问题及影响因素

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

摘要: 将土壤和潜水作为一个相互作用的系统，提出了研究区土壤酸化及地下水碱化、土地沙化、湿地退化、土地盐渍化等主要水土地质环境问题。系统地研究了海河平原北部地区土壤、潜水等地质环境的影响因素。以土壤剖面实测数据为基础，认为土壤环境主要受自然因素的控制，人类活动的影响也不容忽视; 以地下水监测数据为基础，认为潜水环境受自然因素和人类活动双重作用的控制。为研究区水土地质环境保护提供了重要的依据。

Abstract: 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.
