“一只塔影认通州。”历史上的通州,因水而兴,是京杭大运河的起点和水路进京的枢纽。而今,通州也在大做“水文章”。记者了解到,通州作为北京城市副中心,近期将积极开展“海绵城市”建设试点,抓紧实施防洪骨干河道整治工程,到2020年下沉式绿地率达到50%,透水铺装率达到70%以上,新建区域年径流总量控制率不低于85%,构建“三网、四带、多水面、多湿地”的水环境格局。 “A tower of shadow recognition Tongzhou.” Tongzhou history, due to the rise of water, is the starting point of Beijing-Hangzhou Grand Canal and the waterway to Beijing’s hub. Today, Tongzhou is also making big “water articles”. This reporter has learned that Tongzhou, as Beijing’s urban sub-center, will actively carry out pilot projects for the construction of a sponge city in the near future and pay close attention to the implementation of flood control backbone river courses. By 2020, the sunken green space rate will reach 50% and the water-permeable pavement rate will reach 70 %, The control rate of total annual runoff in the newly built area shall not be lower than 85%, and the water environment pattern of “three networks, four zones, multi-surface water and multi-wetlands” should be constructed.
