北京市深井人工回灌现状调查与前景分析

Current situation investigation and prospect analysis of artificial recharge of ground water in Beijing city

北京市地下水人工回灌研究始于 196 5年。 1981年开始生产性深井人工回灌。由于种种原因 ,至 1999年底实际回灌单位由 6 4个缩减至 13个。其间累计回灌量为 10 734.37× 10 4t。据调查 ,停灌原因主要有 :回灌单位停产、转产、回灌井被占 ,回灌井阻塞 ,泵改调频 ,单位搬迁和改换制冷设备等。本文通过对北京市三十几年来地下水人工回灌工作的总结 ,分析了人工回灌在近年来发展停滞的原因 。

The study of artificial recharge of ground water in Beijing City started in 1965,and the productive well recharge began in 1981.Due to various reasons,by the end of 1999,the number of artificial recharge units decreased to 13 from 64 at the beginning.The total recharge adds up to 107,343,700 over the period.Investigation result indicates that the main reasons for the stagnation are:Some recharge units stopped production,or switched to other production;Some recharge wells were blocked or taken over for other purposes;Change of location or reconstruction of the refrigeration facilities of the recharge units.This article concluded the artificial recharge of ground water of Beijing City over the past more than thirty years,and analyzed the reason why the development of artifiial recharge has been stagnated in recent years.The water saving potential of artificial recharge during the sustainable development and construction of the city and the prospect of development in the future are expounded.
