    摘要:

    在滹沱河流域平原区,人类活动和气候变化是造成浅层地下水区域性下降的双重因素,人类活动在浅层地下水从"天然—人工"二元影响转化过程中在时空上经历了怎样的变化,是值得探讨的问题。选用综合指数法,通过筛选人类活动对浅层地下水干扰指标、建立评价体系,对滹沱河流域平原区在不同时代的人类活动对浅层地下水的干扰程度进行了量化研究。研究结果表明,空间上,不同时代都表现出从西部向东部干扰程度逐渐减小;从整个研究区看,干扰程度增大的趋势从西部向东部逐渐推进;干扰程度从分级简单的0~0.4发展到目前0.2~1.0不同级别共存的复杂分布状态。时间上,随着时间的推移,整个研究区的干扰程度都表现出增强趋势,在不同地区增强幅度不一致;人类活动对浅层地下水干扰影响经历了从不占据主导作用→逐渐占据主导作用→几乎完全占据主导作用。

    Abstract:

    Mankind activity and climate variety are the diplex factor of shallow groundwater decline in the valley area of Hutuo River. The questions are worth discussing that how the shallow groundwater changes from crude state to false state and what change the shallow groundwater in space and time has. After all,the discussion will provide the gist for mankind controlling their activities,self-restraining groundwater,and ensuring the harmonious relation between mankind and groundwater. This article chooses integrated index means,filters the disturbing index,and establishes the quantitative analysis system. On the base of the above,the disturbing degree of mankind activities to shallow groundwater is quantitatively analyzed. Results show that spatially,the disturbing degree decreases gradually from the west to the east in different ages; in view of the whole area,the disturbing degree increases from thewest to the east; and the disturbing degree increases from 0~0.4 to 0.2~1.0. Temporarily,the disturbing degree in the whole area increases along with time,but it is different in different areas. The disturbance of mankind activities to shallow groundwater goes through different stages.
