受益于南水北调 11月北京地下水量同比增百个昆明湖

2016-12-29 10:20:13   新京报

随着2014年,南水北调江水进京后,一定程度上缓解水资源紧缺形势,地下水超采程度有所减缓。上述负责人说,2015年北京市地下水开采18.2亿立方米,占总供水量的48%,年末平原区地下水埋深与上年末基本持平,仅下降0.09米。

未来,北京地下水将如何变化?根据《北京市“十三五”时期水务发展规划》,严格水资源开发利用红线管理,按照生活用水控制增长、生产用新水负增长、生态用水适度增长的原则,2020年全市用水总量控制在43.0亿立方米以内。

此外,扩大南水北调中线调水,按照“节、喝、引、存、补”,利用外调水增加密云水库、怀柔水库蓄水量。有序回补地下水,减少开采规模,增加水资源战略储备。

北京市水务局相关负责人介绍,南水北调来水初期,在保持现状水厂供水规模的基础上,首先开展城区自备井置换,减少地下水开采。

根据规划,至2020年,完成城区自备井由公共供水管网置换工作。同时,分年度压减为城区供水的郊区水源地开采量,逐步实现城区地下水采补平衡。

未来北京还将继续通过自备井置换、利用再生水等方式减少地下水开采。

水资源紧张是否有所缓解?

对外调水依赖程度越来越高;仍将继续面对水资源紧张局面

南水进京后,北京的水资源紧张是否得到缓解?对此,北京市水务局相关负责人介绍,南水北调进京后北京市人均水资源量仅为150立方米左右。同时,也存在着对外调水依赖程度越来越高、本地水资源多年欠账偿还和储备恢复等问题。

据了解,北京多年平均降水量585毫米,平均水资源总量37.4亿立方米,属严重缺水地区。上述负责人介绍,尤其是1999-2011年期间,北京遭遇持续干旱,年均降水量仅为480毫米,年均形成水资源量21亿立方米,仅为多年平均的56%,人均水资源量仅为100立方米左右。随着降水量和地表入境水量的衰减,地下水补给量也大幅减少。

此外,上述负责人表示,“十三五”期间,北京还将由重点保障中心城区向同时保障中心城、城市副中心、新城、新机场等多个重点区域转变。北京仍将继续面对水资源紧张局面。
