山东深入实施海洋主体功能区战略，严格落实全海域生态红线制度，创新陆海协同治理机制。2024年， 全省近岸海域优良水质比例达93.6%，保持全国前三。 海洋生态治理并非一时之功，唯有建立长效管护机制并长久运行，才能让碧波永驻。山东全面推行湾长 制，加强"一湾一策"精准治理，打通陆地海洋、岸上水里，实现上下游责任共担、同频共振，让"水清 滩净、鱼鸥翔集、人海和谐"成为滨海常景常态。 水环境好不好，鸟儿用翅膀投票。桑沟湾是山东6个国家级美丽海湾之一，近岸海域水质优良比例多年 保持100%。桑沟湾一度面临严峻的生态问题：沿岸遍布小养殖场、冷藏厂、加工厂，城镇污水、工业 废水直排入海，污染严重。经过清养殖、拆散乱、控源头、修岸线，不仅将清水绿岸还给一方百姓，还 凭借资源优势开发了丰富的旅游项目。 作为全国首批"湾长制"试点之一，青岛构建起市、区、镇三级湾长体系，设置117名湾长，将49个海湾 纳入精细化管理，以"湾长制"推动"湾长治"。 今年暑期，青岛灵山湾迎来客流高峰。对于灵山湾镇街级湾长徐强来说，旅游旺季的到来，也意味着他 的"巡湾忙季"正式开启。 "护海巡湾，每一米海岸线都不能马虎！"徐强告诉记者，巡湾过程中一旦 ...
