中国青年报北京8月26日电 在生态环境部今天举办的新闻发布会上，生态环境部水生态环境司司长蒋火 华介绍，十年来，我国地表水水质Ⅰ-Ⅲ类断面比例从2015年的64.5%大幅提升到2024年的90.4%，提高 了25.9个百分点，"十三五"以来实现"九连升"，到今年年底有望"十连升"。 2024年，全国地表水水质优良断面比例为90.4%，同比上升1.0个百分点，首次超过90%，提前达到"十 四五"规划目标。今年上半年，全国地表水水质优良断面比例为89.0%，继续保持稳中向好态势。 "虽然全国水环境质量持续改善，但从量变到质变的拐点还没有到来，同人民群众对美丽河湖的期待还 有差距。"蒋火华说，他们在一线调研发现，部分地区"房前"的状况还看得过去，但"屋后"垃圾遍地、 污水横流。近期，很多地方通过网络平台反映当地河流、湖泊出现水污染问题，导致有的树木枯死，有 的农田秧苗烂根，有的鱼虾死亡，引起舆论广泛关注。 为更好反映人民群众身边水体状况，"十五五"期间，生态环境部在国家监测网络布局上，继续关注大江 大河的同时，更多向江河支流、小微水体拓展。 蒋火华还介绍，水生态环境目标设置将从单纯的"好Ⅲ水质比例"向综合的"优良水 ...
