| Abstract: | The atmosphere PM2.5 in Dujiachong experimental forest farm of Hunan Academy of Forestry of Changsha City urban were monitored continuously one year with selection of different types of forest stand from September 2014 to August 2015.The results showed that the atmospheric PM2.5 highest value for broadleaf mixed forest,followed by two open space,the lowest for Cinnamomum forest.Atmospheric PM2.5 value has no significant difference between the differ-ent forest,and has significant effects between the different time periods. |
