成都雾霾为什么严重
个人感觉成都之所以雾霾这么严重,最主要的原因还是我国经济发展的方式,所造成的的要知道很多时候我们都是粗放型的发展方式,所以晕进了很多污染型的企业,才造成了这样的结果,还有就是特殊的地理环境,没有风,可以把雾霾吹散,因为成都可能是地是低洼,所以所有的雾霾都无法散去,才造成了这么严重的雾霾。仅代表个人观点。
成都的雾霾是什么引起的?
地形;地处盆地 ,大气环境容量极有限,不利于污染物扩散;地理环境形成的静谧天气! (风速小)不利于污染物扩散稀释,加重了空气污染;气候:成都逆温天气出现较频繁,污染物只能在地面附近聚积而无法扩散,从而使污染加重;成都地区湿度大,多云雾日天气,对雾霾天气的形成起到了促进作用,主要是到了秋收时节,主要受周边燃烧秸秆产生的大量烟尘,加上四川盆地的这种特殊性,就形成了雾霾天气。我分析了成都的数据。得出的结论:现在成都的PM2.5跟北京一样严重我要算到小数点后两位才发现成都稍微比北京严重。这有多么严重。73微克,好吧,这算严重吗。成都和北京的平均值是WHO的24小时上限的3倍。不过,我应该用WHO的年度上限,因为这些数据是年度的数据,而且有研究发现连低于25微克的PM2.还对人的身体健康有害。以这个标准,北京和成都的平均值有上限的10倍,更不用说特别严重的雾霾天。我承认我不老实我做上面的数据对比稍微有点不老实。为什么呢。因为成都和北京一样糟糕不是因为成都越来越严重,而是因为北京的PM2.5最近降低了:北京和成都是雾霾“冠军”,但是中国大城市没有任何地方符合安全的标准。不管在哪个城市,都要保护自己的身体健康,比如戴口罩!原因可能是四川是盆地,工厂多了,这些雾霾散不了。所以,大冬天的,正常来说,我们更期待大太阳天的,但为了不用呼吸雾霾,我们希望下雨,更好是有大风吹那种。
成都为什么雾霾严重
由于近几年成都的飞速发展,成都人民的生活得到了很大的改善,手里都有了钱。所以几乎家家户户都有一部或者两部车。相比较以前来说,成都的雾霾肯定由于环境的影响比较严重。为了减少污染,为了道路能够畅通,成都交通实行了现行制度,同时,凡是雾霾天气都是免费乘坐公交车,从而减少污染的产生。这些举措,都是为了改善大家的人居环境。希望所有的人都能够爱护我们的环境。
