腊月二十八，我沿着河堤徒步至院校街大桥，开启了无人机巡航。无人机刚升空不久，我透过屏幕发现 了一处半隐在水面下的渔网，这是典型的非法渔具。我立刻截图定位，通过巡河APP将问题上传到"县 域数字河湖平台"，整个过程不过几分钟。 数字监管平台大大提高了处置效率。上传问题后，系统会自动精准派单给辖区河长，通常24小时内，隐 患就能彻底清理完毕。 山东潍坊昌邑市水利局工作人员曲成成—— 清清潍河是新年最好礼物 昌邑段是潍河入海前的最后一程，也是全市重要的水源地、生态屏障。 作为一名退伍老兵，今年是我管护潍河的第三个年头。平日里，每半个月我都会沿着河道仔细巡护，重 点盯防那些易出问题、隐患多发的河段；每逢重要节日，巡河就成了每日的必修课。如今有了无人机的 助力，从空中全景巡查，管护工作变得高效又便捷，隐患也无所遁形。看着潍河的生态环境一年比一年 好，我打心底里高兴。 结束巡河回到家，我的手机收到了整改完成的反馈，看着屏幕上干净整洁的河面，心里的踏实感是新年 里最好的礼物。 我操纵着无人机盘旋上升，视野愈发开阔。清澈的河面上，水鸟时而低头啄食，时而振翅掠过水面，灵 动的身影为潍河添了无限生机。 河长制实施之前，潍河也曾历 ...
