北京市河湖水生态健康状况总体良好的同时，河流生态系统也发生了重大转变。过去，本市部分河流水 体中，浮游植物和浮游动物等初级生物占主导地位，通常具有水体富营养化特征，当水体中氮、磷等营 养盐含量较高时，易导致藻类大量繁殖，出现水华。"当水体透明度降低，水质变差，就形成了典型 的'藻型浊水'。"北京市水务局水生态监测中心相关负责人介绍，近年来，北京市持续推进水环境治理 工作，成效显著。得益于此，北京市河流水体中氮、磷等营养盐含量逐渐下降，沉水植物覆盖率大大提 高，构建出的"水下森林"已成为优势群落。 "沉水植物的根系发达，能固着底泥，可以通过释放化感物质抑制藻类生长，防止水华，从而改善水体 的透明度和水质，促使河流生态系统逐渐转为'草型清水'。" 北京市水务局水生态监测中心相关负责人 介绍，草型清水生态系统的形成，可为水生生物提供更适宜的生存环境，标志着本市水生态环境正朝良 好的方向发展，对提升城市生态质量有着深远意义。 除河流生态系统的重大转变外，北京市湖泊和水库在发挥调蓄功能的同时，也成为生物多样性最丰富的 生态系统之一，孕育出了极为丰富的生物资源。2024年，全市153个监测水体中共检测到浮游植物459 种 ...
