诗意盎然!故宫北院南侧水域迎来白鹭、苍鹭
时间:2020-10-24 00:31:14阅读:2535次来源:星辰影院 近日,海淀区水务局工作人员首次发现崔家窑水库有白鹭、苍鹭等水鸟现身,并在附近栖息觅食。这个面积约150亩的水面紧邻正在施工的故宫北院,近些年通过截污、清淤、补水等一系列生态修复工程,已经初步显现生态成效。
崔家窑水库位于南沙河上游,是宏丰渠、团结渠和五一渠三条支渠的汇聚处,水域面积150亩左右,有一座水闸用于调控上下游行洪。“2016年,这里曾经是市级挂账的黑臭水体。”海淀区水务局河道所副所长代庆军回忆,“走在路边儿都能闻见臭味儿,水也是浑浊不清的。”
代庆军说,2017年开始,海淀区水务局启动了崔家窑湿地生态治理工程,一方面对支渠开展截污治污,另一方面对水下淤泥进行清理,清淤总量达到了28万立方米。之后再利用稻香湖再生水厂的出水,对上游团结渠支渠进行补水,日补水量达到1.5万立方米。补水最终全部流入崔家窑水库,既恢复了水库生态基流,同时提高了水体的流动性,提升了水体的自净能力,改善了水质。
今年,海淀区水务局还在宏丰渠入崔家窑水库的入河口增加了两台曝气机,提高水体的含氧量,增加水的活力。前不久,水面上还增加了两块总面积近200平方米的生态浮床,通过在浮床上栽种菖蒲、苔草等水生植物,提高水的自净能力。经过3年的治理,如今的崔家窑水库已经呈现出良好的生态效应,引来不少水鸟光临。值得一提的是,崔家窑水库正巧位于正在建设的故宫博物院北院的南侧,这片水域完成生态治理,也将给未来的故宫北院营造良好的水环境。
下一步,海淀区水务局还将在崔家窑水库设立更多曝气机,并种植荷花、放生更多水生动物,增加崔家窑水库生态多样性,为南沙河流域水生态提供坚实的保障。
