我们对城市和周边地区的PM2.5浓度进行了检测和比较，并进一步调查了城市化对中国各地市城市PM2.5浓度的影响。大多数县的PM2.5年浓度都超过了世界卫生组织的空气质量指南10微克/立方米(3)。这些地区主要分布在四川省东部沿海和东南部；85个城市的城市PM2.5浓度(城市PM2.5)大于周边地区的PM2.5浓度(>；10µg/m(3))。这些城市主要位于京川、沪桂一带。此外，城市(PM2.5)低于(
We examined and compared PM2.5 concentrations in urban and the surrounding regions, and further investigated the impact of urbanization on urban PM2.5 concentrations at the Chinese prefectures. Annual PM2.5 concentrations in most prefectures were greater than 10 mu g/m(3), the air quality guideline of the World Health Organization. Those prefectures were mainly distributed along the east coast and southeast of Sichuan province; The urban PM2.5 concentrations (Urban(PM2.5)) in 85 cities were greater than (>10 mu g/m(3)) those in the surrounding area. Those cities were mainly located in the Beijing-Sichuan and Shanghai-Guangxi belts. In addition, Urban(PM2.5) was less than (
