| 关 键 字：太行山山前平原,地下太位,下降量 |
| 摘 要：通过对太行山山前平原地区地下水位变动过程的分析发现，该区地下水位多年平均年下降逮率为0.7m ,20世纪80年代该区地下水位季节变动量和季节恢复量变化平稳。90年代以来变动量和恢复量显著增大，年降水量与年地下水位下降速率呈高度线性相关，相关系数r=0.77 98,年降水I每增加100mm则地下水位可回升0.66m。只有建立切实可行的农业节水系统，加强山区的林业生态综合治理，才能缓解该区地下水位持续下降。 |
| 关 键 字(英文)：Taihang piedmont, Groundwater level, Declining quantity |
| 摘 要(英文)：We find that the average declining quantity of groundwater level is 0.7 meter per year through analyzing change process of the goundwater level in Taihang Piedmont. The season-changing quantity and the seasonre suming quantity changed little in 1980's and increased very quickly in 1990's. Relationship between the precipitstion and the declining quantity of the groundwater is highly linear correlation and the correlation coefficient is
0.7798. When yearly precipitation increases 100 millimeters, the groundwater level will ascend 0.66 meter. Only if water-saving agricultural system is constructed, and only if integrative management of forestry ecology is reinforced,
then the situation that groundwater level is declined gradually can be controlled. |
