北京市平原区地下水资源变化情况分析
Dynamics and evaluation of groundwater resources in the Beijing plain
摘要
Abstract
This study investigates changes in groundwater levels and resources within the Beijing Plain over the past two decades using multiple research methods.Key findings demonstrate significant impacts following the South-to-North Water Diversion Project:Groundwater levels recovered substantially,with the Yongding River system showing rises of 19.45 m(unconfined aquifer)and 23.16 m(confined aquifer),while the Chaobai River system experienced a cumulative rise exceeding 30 m.From 2015 to 2024,total groundwater storage increased by 64.11×108 m³,averaging 6.41×108 m³ annually.This storage variation resulted from altered recharge and discharge components.Recharge increased by 2.6×108 m³/a compared to the 2000-2014 period.Concurrently,groundwater levels in the Yongding River system rose by 19.45 m in phreatic wells and by 23.16 m in confined wells,while the Chaobai River system experienced a cumulative rise of over 30 m.In terms of groundwater resources,from 2015 to 2024,the total change in groundwater storage in the plain increased 64.11×108 m3,with an average annual increase of 6.41×108 m3.The variation in groundwater storage was influenced by both recharge and discharge.For recharge,the period from 2015 to 2024 saw an increase of 2.6×108 m3/a compared to 2000-2014.From 2017 to 2022,the cumulative ecological replenishment reached 10.42×108 m3,while groundwater extraction decreased from 19.6×108 m3 in 2014 to 12.44×108 m3 in 2023.关键词
