| 摘 要： | 滹沱河出山口修建黄壁庄和岗南水库后,滹沱河成为间歇性过水的泄洪通道。在丧失河水对河道两侧地下水补给功能的前提下,距河岸不同距离的浅层地下水表现出不同的动态变化特征,并且在间歇性通水时发生不同响应变化。根据多年来研究区地下水动态监测数据分析,总结出长期人类活动干扰下滹沱河近岸地下水响应河道过水的动态变化规律:从时间上看,不同区位和距河道远近不同的地下水位升降规律各异;从空间上看,随着距河道距离的增大,地下水的响应强度和响应速度逐渐减弱;在河道常年有水和间歇性过水不同背景条件下,地下水的年际回升量变化随距河道距离不同而表现出明显差异。

| Abstract: | The Hutuohe River has been a flood discharge alleyway after the build of the Huangbizhuang and Gangnan reservoirs in the exit of Taihangshan.Because the surface water is holded up,the shallow groundwater is bankrupt in discharge function of the surface water.Under the condition of intermit flood,the shallow groundwaters in different distances from riverway appear marked spatiotemporal dynamic changing rules and different responds.Based on the analysis of long-term observation data,this article sums up the dynamic changing rules as following,in the view of time,the groundwater levels in different distances from the river have different rising and falling rules,from the viewpoint of space,the groundwater level changes slow down gradually with the distance from the center of the river growing. |
