Abstract：
Reports the particle number concentrations of atmospheric particles for 132 areas including all provinces except Hong Kong, Macao and Taiwan in China. Indicates the particle number concentrations are all less than 3×105/L except one area and the data are obviously lower than those twenty years before.
