摘要
以北京、天津、河北、河南、山东和山西6省（市）2000~2010年的降水量和地下水动态变化数据为依据,分析了11 a来北方6省（市）地下水位的变化特征。结果表明：研究区地下水位主要呈现下降趋势,其中北京、河北和河南省地下水位下降趋势明显,天津、山东和山西省地下水位表现为弱下降;确定了地表水减少和人类活动是影响地下水位下降的主要因素,并提出了相应的建议措施。
By collecting and analyzing data of the precipitation and the variation of groundwater during 2000-2010 in Beijing,Tianjin,Hebei,He＇nan,Shangdong,Shanxi,the characteristics of the groundwater level variation in six provinces over the past 11 years was analyzed.The results showed that the groundwater level in this areas had a downward trend,these six provinces had different degrees,Beijing,Hebei and He＇nan had an obvious downward trend,Tianjin,Shangdong and Shanxi had a weak trend.The main factors which influence the variation of groundwater level were surface water reducing and human activities.At last,the corresponding measures were suggested.
