Study on the Evolution Characteristics and Main Control Factors of"JZH"Funnel,Hengshui Area
摘要
Abstract
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.关键词
