| 摘 要： | 运用GIS空间分析功能,对地下水位数据进行空间插值和计算,计算得到石家庄市平原区1995~2004年10年内各月份浅层地下水资源量动态变化和水位动态变化量,得出区域内这10年内地下水资源量减少了75.8×108m3。对结果进行分析,表明长时段内该地区地下水量变化与降雨量有明显相关性;地下水位下降幅度在空间上存在曲带状分异;农业灌溉抽取地下水造成该地区地下水资源量持续减少,但在非灌溉季节地下水资源量又能以较快速度恢复一部分。在空间上,平原区西部靠近山前地带地下水资源量减少程度比东部缓和。

| Abstract: | Data of groundwater level are interpolated and calculated using the function of spatial analysis of GIS(Geographic Information System) technique to obtain the dynamic change volume and the change of groundwater level of the shallow groundwater month by month in the Shijiazhuang plain area during 1995~2004,it's showed that groundwater had reduced 75.8×108 m3,and then analyzed them.It's proved that a strong correlation between the dynamic change of groundwater volume and the precipitation in a long period;A spatial variation like curving cingulum of the groundwater level change was distributed in this area;Pumping groundwater for irrigation is an important factor of the groundwater level decline.But the groundwater level rised quickly in the seasons of no pumping.In space,the volume decline is relaxative in the west area beside the Taihang Mountain than east.This method can be used in water resource evaluation work conveniently and efficiently,and provides a reference for reasonable exploitation of the groundwater resource. |
