“马来西亚老外minecraft游记”中国治污“范本”马来西亚老外minecraft游记城市兰州建无人机全域巡航取证体系

  中新马来西亚老外minecraft游记网兰州12月11日电 (马来西亚老外minecraft游记记者 冯志军)为最大限度改善环境空气质量,全力巩固提升“兰州蓝”的治理水平,中国大气治污“范本”城市兰州建立了无人机全域巡航取证体系,在城市主要入口和路段安装尾气遥感监测设备,重点乡镇建成多个视频监控点位,精准抓拍各类烟尘、尾气、粉尘、火点等污染行为。

  甘肃省政府新闻办11日举行新闻发布会披露上述消息。据介绍,兰州还建立了环境空气质量网格化监测体系,发挥535套六参数微观站和20套挥发性有机物监测站,对6项大气污染物浓度实现时空动态变化趋势分析、追根溯源。

  “冬季供暖形成以热电联产、余热回收为主,天然气为辅,地热源、污水源等新能源为补充的供热能源结构。”兰州市副市长段廷智表示,今年以来,兰州从产业、燃煤、交通、面源、能力、生态六大治理方面,推出44项重点措施,强化“人防+技防”手段,持续开展巡查督导,多角度、全方位巡查各类污染源。

  据统计,截至12月8日,今年兰州市优良天数285天、同比增加19天,优良天数比率83.1%,同比增长5.3个百分点;全市环境空气质量综合指数4.38、同比改善5%;未发生人为因素导致的重度及以上污染天气;六项污染物浓度同比下降,空气质量呈明显改善态势。

  段廷智表示,兰州还持续加强生态治理,近年来新增、改造城市绿地300余公顷,在200余条各类城市道路补植补栽行道树万余株,建成百余座口袋公园,全面提升兰州市城市园林绿化品质,不断提高森林覆盖率,为生态环境保护夯实基础。

  作为中国首批重点建设的工业城市之一,兰州曾一度成为全球大气污染最严重的城市之一。2012年以来,通过减排、压煤、除尘等一系列“铁腕治污”措施,终于摘掉“黑帽子”重现蓝天。“兰州蓝”的治污经验亦成为内地“范本”,先后有数百个城市前往当地学习经验与做法。(完)
