我是土生土长的北京人，今年60多岁了，打小就住在北京海淀区树村。我家附近有一个很漂亮的地方， 叫清河之洲，旁边一条小河，从我的少年时代起，大家都习惯称之为小清河。 小清河里满是故事。她坐落在三山五园中的圆明园以北，西起安河桥北的龙背村，东至二河开。河面原 来最宽的地方有近百米，窄处有几十米，河道曲曲弯弯。河南岸有座土山，似一条土龙守在岸边，可以 防止水患侵扰三山五园地区。小清河的水系灌溉着周边百十亩水田，水田里生长着非常有名的京西稻。 稻花飘香的季节，那画面仿佛江南水乡。 后来随着工业化的进程，小清河沿岸建了不少工厂，水质受到影响，小清河变成了"小浑河"，没人再愿 意靠近这条脏水河。 最大的变化发生在两年前，海淀区政府重新铺设污水管道，岸边运来新土，播下花籽、栽下树苗，步道 沿着河岸慢慢铺就，最终形成了"京西北的生态绿带"——清河之洲。 傍晚时分的清河之洲。 何 丽摄（人民视觉） 近年来，北京市海淀区以系统治理思维推进水岸共建，定期举办农耕体验、河畔影院等活动，不仅丰富 了市民生活，更激活了区域文化活力。小清河的变迁，是北京推进高质量发展、建设美丽中国的缩影。 《 人民日报 》（ 2025年10月23日 04 ...
