晒晒蓝天背后的秘密之一:为何北京颜值爆表?

2017-10-12 10:28:42   北京时间

“这种特别漂亮的景色只有空气特别好的时候才有,这也反映出好天气慢慢变成常态了。”邹毅解释说。

在拍摄蓝天之余,邹毅也会把他的目光放到更细致的地方。

“北京通过这些年的治理,燃煤控制得差不多了,散乱污也都清理了,餐饮烧烤控制的力度也很大,北京油品和欧洲标准也差不多了,而且现在北京第三产业的占比超过80%,北京自身的污染物排放应该是越来越低了。”邹毅感叹说。

不过,邹毅也表示,根据研究,机动车——特别是柴油大货车和大型工程车的排放污染仍然不可小觑。

来自北京市环保局相关人士的数据也显示,机动车排放对北京市PM2.5的贡献率超过30%,是北京空气最主要的污染源。而国三及以上排放标准的重型柴油车排放的氮氧化物和一次颗粒物可占北京全市机动车排放总量的50%以上和90%以上。

“为什么往往一大早天气不好,因为夜间大货车跑的太多了。要知道,一辆大货车就相当于200多辆小汽车在跑。而且夜里天黑也看不见冒黑烟,人也少,没人举报。”邹毅解释说。

“从上个月开始北京在六环外对进京柴油大货车进行督查控制,对于北京有巨大的好处。”邹毅对当前密集发布的政策也有着更为深刻的理解,“北京刚刚发布的土石方工程的停工令,不仅可以杜绝扬尘,还相当于一并减排了作为排放大户的大型车辆和机械排放。”

邹毅从2013年起上班时开始公交出行,半年多前,随着共享单车渐成规模,骑车上下班成了更方便的选择。“以前都是坐地铁,下了地铁步行,现在还可以骑车,其实大家也愿意选择让环境更好的出行方式。”邹毅说。

事实上,伴随着公交网络的加密以及共享单车的出现,绿色出行已经越来越成为一股潮流。

由多家权威数据机构发布的《2017年第一季度中国主要城市交通分析报告》显示,驾车用户在10公里以下短距离出行用户占比开始减少,尤其是5公里以下下降更为明显。而在共享单车热门区域,工作日全天北京拥堵延时指数更下降了7.4%,对减排贡献明显。

事实上,在这背后,是越来越多的人开始关注蓝天、参与环保。

邹毅说,他也希望自己一个人的“一目了然”能够变成更多人参与的“众目睽睽”,一起让北京的蓝天更蓝。
