【摘要】 根据北京通州地区甘棠乡水源地多年监测的数据 ,所建立的水资源管理模型 ,经过近 10 a的运营 ,在管理方案的指导下 ,逐步实行农业喷灌措施 ,节水约 5 2 5× 10 5 m3/ a。污水处理已达到 5 0× 10 5 m3/ d,充分满足农业灌溉用水。由于继续增加深层地下水的开采 ,导致深层水位仍继续约以 1m/ a的速度下降。因受潮白河上人工湖补给的影响 ,浅层水水位出现上升趋势 ,最大约 4m。隐伏基岩水的初期水量为 5 0 0 0 m3/ d,但水位下降较快 ,可作应急水源。目前 ,水源地工农业和生活用水总量为 2 715× 10 5 m3/ a,可补给水资源大部分是地表水和净化水 ,总量约 70 0 0× 10 5 m3。更多还原

【Abstract】 The scenario of water resources managemet been established based on monitoring data during many years in Gantang area,Tongzhou county,Beijing city.Some expected results on reasonable development and utilization of water resources and enironment of protection have been abtained in the last decade.The spray irrigation has been implemented gradually,saving groundwater 425×10\+5m\+3/a.The amount of sewage water being trealed reachs 50×10\+5m\+3/d, providing sufficient water for agriculture due to over exploitation of deep aquifer.The level of shallow ground water is goingup about 4m because of the recharge of artificial lake on the Chaobai river.The explored covered karst ground water is can be reserved,although the outflow is 5000m\+3/d the level goes down quickly.The tolal water demand of industry and agricultrure is about 2715×10\+5m\+3/a,nevertheless,the rechargeble ground water is about 7000×10\+5m\+3/a.更多还原
