Abstract: Abstract Due to the small area and large population, the per capita capacity of eco-environment in Jiangsu Province is relatively small. So, the rapid urbanization in Jiangsu will inevitably make negative effects on the ecological environment, which PM2.5 pollution is one of the important negative effects of them. Based on the impervious surface data and the average annual PM2.5 concentration from 2000 to 2017, the Environmental Kuznets Curve between the proportion of built-up areas and PM2.5 was established to analyze the impact of urbanization on PM2.5 concentration. The results show that there are differences in PM2.5 pollution patterns among different regions in Jiangsu, which are mainly manifested in the shape of the relationship curve, the location of inflection point and the differences in the pollution stage of each region. The relationship curve of Jiangsu Province, South of Jiangsu and Middle of Jiangsu showed N-type, and only North of Jiangsu showed the inverted-U. Most cities are in the middle section of the N-shaped curve and the right half of the inverted U-shaped curve. Only Huai’an, Yancheng and Suqian in North of Jiangsu are in the first half of the inverted U-shaped curve. In the future, we should pay more attention to the pollution of PM2.5 in urban expansion in these cities.
