摘要
[目的]研究近年淮北平原浅层地下水空间动态变化特征。[方法]参照美国地质调查局于2002年在美国宾夕法尼亚的基于数理统计学方法的地下水动态预警研究方案，利用1975～2008年淮北地区71个站点逐月地下水动态资料，研究地下水埋深的年内、年际及空间动态变化特征。[结果]淮北平原浅层地下水多年平均埋深从南部的1 m向北部的3 m逐渐增大，1990年之前地下水年均埋深较浅、变幅较小，1990年以后地下水埋深变幅加大，埋深加深，但2003～2008年埋深又趋向变浅。北部砀山县、萧县、亳州市地下水埋深较深，南部颍上县、凤台县、五河县、阜阳市地下水埋深较浅。[结论]为淮北平原农业发展提供了基础数据。
Abstract
Objective] The aim was to study dynamic changes of shallow groundwater in Huaibei Plain.[Method] According to groundwater dy-namic early warning system in Pennsylvania, USA in 2002 based on the mathematical statistics method by United States Geological Survey, using monthly groundwater dynamic data of 71 stations in Huaibei Region during 1975-2008, annual and spatial dynamic characteristics of groundwa-ter bury were studied.[Result] Results showed that the average groundwater depth was increasing from 1m in the south region to 3 m in the north region; shallow groundwater depth were at a higher level with a relative small amplitude before 1990 while it performed opposite after 1990;northern Dangshan, Xiaoxian and Bozhou had a deeper shallow groundwater depth than that in southern Ying, Fengtai, Wuhe and Fuyang.[Con-clusion] The study can provide basic data for agriculture development in Huaibei Plain.
