北京五年来城市生态环境持续改善 打造国际一流和谐宜居之都

2017-06-14 13:11:49   国际在线

国际在线报道(记者 杨琼):记者13日从北京市政府新闻办公室举行的发布会上获悉,通过五年的努力,北京市空气、交通、水环境等生态环境持续改善。空气中细颗粒物(PM2.5)下降23.7%。交通绿色出行比例达71%,交通拥堵加剧势头得到有效遏制。城市核心区共拆除违法建设6300多处。

当天的发布会上,北京市环保局局长方力介绍说,通过五年的努力,北京空气质量持续改善。2016年,空气中细颗粒物(PM2.5)年均浓度为73微克/立方米,较2012年下降23.7%。地表水水质稳中向好。密云水库等主要集中式饮用水源地水质持续符合国家标准。地下水水质保持稳定;土壤环境质量总体良好,声环境质量基本稳定,辐射环境质量保持正常,生态环境状况指数继续保持在“良”的等级。

根据官方规划,北京市将建设成为国际一流的和谐宜居之都。方力介绍说,北京市正在积极研究制定未来五年清洁空气行动计划,以绿色生活为变化带来的全社会文明的进步是未来城市的大亮点。方力说:“作为北京超大型的城市,在过去的五年我们有一张成绩单,刚才大家也能感受到,工程减排占了重要的分量,但是对于这样的城市,我们的城市运行保障,污染排放构成,生活类所占的比重将会越来越大。所以说跟管理要效益,跟绿色生活要减排,要环境质量的改善是我们下一步工作的重要着力点和发力点。所以未来的五年,肯定是空气质量治理由量变像质变转变的关键时期,首先就是我们的工程减排,煤炭消耗量去年降到了1000万吨以下,未来五年降到500万吨以下。”

除了空气质量,拥堵的交通也被看做是“大城市病”的病症。在发布会上,北京市交通委员会主任周正宇表示,过去五年,北京市轨道交通运营里程从372公里增长到574公里,城市道路里程从6258公里增长到6374公里。绿色出行比例71%。交通整体安全顺畅,交通拥堵加剧势头得到有效遏制,交通可持续发展能力切实增强,有力支撑了首都经济社会发展。

周正宇说:“五年来,北京市结合‘城市病’治理,控制人口规模、疏解非首都功能、优化职住平衡、减少通勤出行距离等。大力提高交通供给能力,在道路、枢纽、公交专用道、自行车道、停车位、驻车换乘等设施体系中全面落实提高规划实现率。通过运用法律、经济、科技和行政手段限制和调节小汽车的拥有和使用,调控总量、降低小汽车出行总量。”
