摘　　要：应用统计学方法对衡水地区1975—2020年的地下水位降落漏斗(以下简称“漏斗”)调查监测数据进行分析,研究“冀枣衡”漏斗演化特征及主控因子。结果表明,近45年来“冀枣衡”漏斗中心水位持续下降,多年平均下降速率2.1 m/a。漏斗封闭范围由南向北不断扩展,2005年达到最大,随后有所减小。相关性分析发现地下水开采是影响“冀枣衡”漏斗发展的主控因子。应用回归分析和GIS技术,研究表明水文地质因子对研究区水位空间分布具有一定的贡献,不同时期影响的解释率为:1984—1992年为38.2%、1992—2005年为21.2%、2005—2016年为4.5%、2016—2020年为16.3%。本研究为衡水地区的地下水位修复提供技术参考。Statistical methods were applied to analyze the groundwater funnel survey and monitoring data in Hengshui area from 1975 to 2020 to study the evolution characteristics and main control factors of“JZH”funnel.The results show that the water level in the center of“JZH”funnel has been declining continuously for the past 45 years,with a multi-year average decline rate of 2.1 m/a.The closed area of the groundwater funnel has been expanding from south to north,reaching the maximum in 2005,and then decreasing.The correlation analysis found that groundwater extraction is the main controlling factor to affect the development of the“JZH”funnel.Applying regression analysis and GIS technology,the study shows that hydrogeological factors have a certain contribution to the spatial distribution of water level in the study area,with the explanation rate of the influence in different periods being 38.2%from 1984 to 1992,21.2%from 1992 to 2005,4.5%from 2005 to 2016,and 16.3%from 2016 to 2020.This study provides a technical reference for groundwater table restoration in the Hengshui area.
