| 以滹沱河流域平原为研究区，选取地下水开采量作为人类活动影响地下水变化的特征值（母序列），开采机井数量、水浇地面积等7 个因子作为影响地下水变化的变量指标（子序列），采用综合指数法和MapGIS技术，借助1.25× 1.25km2剖分体系，量化研究了自20世纪60年代以来不同时期人类活动对浅层地下水影响程度演变时空特征。自20世纪60年代以来，人类活动对滹沱河流域平原浅层地下水位变化的影响程度不断加剧，影响程度“低”或“较低”布区面积不断缩小，“较高”和“高”分布区面积不断扩大，这些变化与地下水位下降时空变化特征具有较好的吻合性。目前，人类活动对地下水变化影响程度“较高”和“高”级的分布区面积已占滹沱河流域平原总面积的83.8 ％。规范人类合理利用地下水，加强地下水涵养势在必行。 |

| The influences of human activities in different periods since 1960s on spatial-temporal variations
of shallow groundwater in the Hutuo River plain were studied. The exploitation of the groundwater was selected as the eigenvalue （primary-sequences ）to indicate the groundwater variations affected by human activities ，while numbers of the pumping wells ，area of the irrigable land and other 5 fac-tors were regarded as the variable indexes （sub-sequences ）which can influence the variations of the groundwater. Then ，synthetically index method and MapGIS technique were adopted to develop this investigation by dint of 1.25×1.25km2 partitioning system. Results show that since 1960s variations of the shallow groundwater levels in Hutuo River plain gradually severely due to the influence of anthropogenic activities ，the area of low or lower effect distribution regions affected by anth-ropogenic activities were decreasing ，while the area of high or higher effect distribution regions were still increasing. These changes were consistent with the spatial-tempo-ral characteristics of the falling groundwater level. At present，the area of distribution regions，in which the shallow groundwater was high or higher influence by anthropogenic activates ，is account for about 83.8% of
the total area of Hutuo River plain. |
