基于时序InSAR的衡水市地面沉降与深层地下水关系研究
The study of the relationship between ground subsidence and deep groundwater in Hengshui City based on time-series InSAR
摘要
Abstract
The long-term over-extraction of groundwater in Hengshui City has led to a continuous decline in the deep groundwater levels,which in turn has caused serious ground subsidence issues,threatening the sustainable develop-ment of the regional economy and ecological environment.Studying the distribution characteristics of ground subsid-ence and its response relationship with deep groundwater levels is of great significance for preventing and controlling subsidence disasters and formulating scientific policies for groundwater development and utilization.This study is based on SBAS-InSAR data and deep groundwater level monitoring data from 2018 to 2022.It analyzes the character-istics of ground subsidence in Hengshui City and its response relationship with deep groundwater level changes across three time scales:multi-year averages,inter-annual variations,and monthly fluctuations.Using the cross-wavelet transform analysis method,this research quantitatively investigates the periodic characteristics of ground subsidence and deep groundwater level evolution and their time-lag relationships at representative points.The research results indicate that:(1)From 2018 to 2022,Hengshui City was in a state of subsidence as a whole,with areas that have a cumulative subsidence of over 100 mm accounting for 86.54%.This has formed two distinct subsidence zones,one stretching from Raoyang to Shenzhou and the other at the junction of Jizhou-Zaoqiang to the boundary between Fucheng County and Jingxian County.(2)The study area was in a"rapid subsidence"phase from 2018 to 2019,with the highest subsidence intensity occurring in Anping County and Raoyang County.After 2020,it entered a"slow sub-sidence"phase,where the recovery of deep groundwater levels significantly slowed down the subsidence rate.By 2022,the average subsidence amount decreased to 4.7 mm.However,some areas continued to experience further subsidence as their groundwater levels were lower than the historical minimum groundwater levels.(3)The groundwa-ter level falling below the historical minimum groundwater levels is a key driving factor for subsidence,and the result-ing inelastic compression is the main component of the subsidence amount.This indicates that preventing deep groundwater levels from falling below historical lows is an effective measure for controlling ground subsidence.(4)The average time lag between ground subsidence and changes in groundwater levels at six representative points is 38.83 to 66.99 days,demonstrating a significant lag effect in the compaction of aquifers in the area.The findings of this study can provide a scientific basis for subsidence prevention and control,water resource management,and regional sustainable development in the Hengshui area.关键词
