摘要:

利用中日合作项目在华北平原设置的自动监测设备KADEC-MIZU II 型地下水水位自计仪, 对2004-2006 年39 处浅层地下水水位监测的结果, 结合区域影响地下水宏观动态类型 的主要因素,如地形地貌、地下水埋深、地下水开采程度、地下水漏斗以及河流湖泊等, 叠加各影响因素分区图得到地下水动态影响因素综合分区图, 结合观测孔地下水水位体现的动态 特征, 将华北平原地下水观测点分为山前开采型、山前侧向补给- 径流- 开采型、中部河道带补给- 开采型、中部地下水浅埋区降水入渗- 蒸发型动态、黄河影响带侧向补给- 蒸发型 动态和滨海平原区入渗- 蒸发型6 大地下水动态类型。在此基础上阐明了大区域范围内不同类型地下水水位年内及多年动态变化的特点, 比较了不同类型区地下水动态所受影响因素的不同。

Abstract:

The groundwater level of 39 unconfined observation wells from 2004 to 2006 in North China Plain (NCP) was monitored using automatic groundwater monitoring data loggers KADEC-MIZU II of Japan. The automatic groundwater sensors were installed for the corporation project between China and Japan. Combined with the monitoring results from 2004 to 2006 with the major factors affecting the dynamic patterns of groundwater, such as relief, depth of groundwater level, discharge extent and rivers, the dynamic regions of NCP groundwater were compiled. According to the dynamic features of groundwater in NCP, six dynamic patterns of groundwater level were identified, including discharge pattern in the piedmont plain, lateral recharge-runoff-discharge pattern in the piedmont plain, rechargedischarge pattern in the middle channel zone, precipitation infiltration-evaporation pattern in the shallow groundwater region of the central plain, lateral recharge-evaporation pattern in the recharge-affected area along the Yellow River, and infiltration-discharge-evaporation pattern in the littoral plain. Based on this, various dynamic patterns features of groundwater were interpreted and different factors of different dynamic patterns were compared.

Key words: North China Plain, shallow groundwater, dynamic region of groundwater
