Jing Ji Ri Bao· 2025-07-15 23:59
生态筑基,筑牢黄河安澜防线。"十四五"以来,甘肃实施了一系列系统性生态修复工程,成效显 著。一是水源涵养能力稳步增强。在甘南草原,通过实施山水林田湖草沙一体化保护和修复工程,天然 草原产草量和草群高度均达10年以来的峰值。这种以自然恢复为主、人工修复为辅的治理模式,为脆弱 生态系统修复提供了新范式。二是水质提升实现历史性突破。黄河干流出境断面水质连续9年稳定保持 Ⅱ类标准,黄河流域41个国控断面水质优良比例达97.56%。三是水资源集约利用成效斐然。甘肃地下 水超采区面积较2016年减少1059平方公里,严重超采区全面清零。 智慧赋能,创新流域治理模式。面对复杂多元的生态治理挑战,甘肃积极探索科技赋能新路径。通 过构建智慧黄河监测网络,在黄河兰州段建成19座水质自动监测站和251套智能监控设备,形成实时监 控、报警溯源、实景三维的网格化监管体系。该平台将人工监测范围缩小40%,大幅提升污染溯源效 率。通过打造生态科研平台集群,建成甘南草原生态系统野外科学观测研究站等9家国家级野外观测 站,整合省级重点实验室37家。设立省级生态文明建设重点研发专项,每年投入1000万元支持生态技术 攻关。通过推动流域协同治理, ...

以标识化管理促进差异化精准化监管
Zhong Guo Huan Jing Bao· 2025-07-15 23:13
首先,标签建立要因地制宜。要搭建符合辖区特征的标识化管理框架。空间维度可以按区域划分为生态 敏感区、工业集中区等标识;行业维度可以对火电、印染等不同行业设定特征污染物标识;行为维度可 以整合历史违法记录、群众信访频次等动态标识。在此基础上,要根据本地产业结构特点、生态环境治 理状况等细化标签维度,补充个性化标签,如化工园区还可增设危废产生类别、挥发性有机物排放量等 标签。 近日,生态环境部办公厅印发《关于严格规范生态环境行政检查大力提升执法质效的通知》,创新性提 出"强化标识化管理"。笔者认为,这是用数据标签重构执法监管逻辑的重要举措。 这一举措将检查对象的分布区域、行业产业类型、排放污染物类型、违法记录、信访举报情况等要素, 转化为可量化可追溯的"数字标识",通过对检查对象精准"画像",为综合统筹现场检查活动提供依据, 有助于优化有限的执法资源,为实现差异化精准化监管提供保障。 在过去的传统监管工作中,一些地方的执法力量如同"撒胡椒面"式分配,容易导致出现高风险企业查不 透、低风险企业反复查的情况。而标识化管理通过数据标签精准定位监管重点,使执法资源投入与环境 风险等级相匹配,实现"好钢用在刀刃上"。 标识 ...
