| 摘 要： | 由于人类活动的累计影响,地下水脆弱性不仅在空间上变化,在时间上也发生变化。本文从三个阶段对滹沱河流域地下水脆弱性进行了评价,证明了地下水脆弱性随时间的变化,并分析了其演化趋势和演化特征以及演变机理。结果表明:由于地下水的长期大量开采,使地下水脆弱性影响因素(如,地下水位埋深、包气带厚度和降雨入渗系数等)发生了变化,而使地下水脆弱性发生变化。

| Abstract: | The aquifer sensitivity changed not only with space,but also with time because of the accumulative impacting of human activities.The aquifer sensitivity was assessed from three stages.Its transmuting characters and change mechanism were analyzed.The results indicated that aquifer sensitivity changed because of the change of factors,such as groundwater depth,cadose zone thickness and permeability coefficient which was resulted from in groundwater intense exploitation longterm. |

| Keywords: | groundwater sensitivity transmuting character human activities cumulative influence |
