中文摘要：
以德州市武城县为研究区,采用3S技术,布设采样点,于2011年进行两次野外采样,基于室内试验得到地下水矿化度数据,并结合1972年地下水矿化度数据,利用ArcGIS软件进行反距离加权空间插值处理,分析了该地区地下水矿化度时空变化特征。研究结果表明：研究区地下水矿化度空间变异趋势明显,数值为自东南区域的〉1～2g/L逐渐增加到西北区域的〉4～5g/L。地下水矿化度年内季相变化显著,春季矿化度均值为2.628g/L,冬季为1.748g/L。地下水矿化度较之1972年总体呈现下降趋势,平均降幅为1.52g/L。该结果对研究区盐渍化土壤的水盐调控及地下水资源合理开发利用具有重要意义。
英文摘要：
The condition of the groundwater quality is serious in Northwest Shandong. 3S technology is used to emplaee sampling points, two field surveys were carried out in 2011. Based on the groundwater TDS data of laboratory experiments as well as the data of 1972,inverse distance weighted spatial interpolation processing used ArcGIS. The results show that： spatial variability tendency of the groundwater TDS is evidently in the study area, the data from the southeast region of 〉2g/L gradually increase to the northwest region of 〉4-5 g/L. Seasonal changes during the year significantly, the mean in spring is 2. 628 g/L. In winter, it is 1. 748 g/L. Groundwater TDS shows a downward trend compared to 1972, the average decline is 1.52 g/L. The results are of great significance to water salinity control and rationally exploit groundwater resources in the research area.
