Abstract: The home and abroad latest research progress on receptor model which is used for the source apportionment of fine particulate matter PM2.5 is summarized. The principles，applications，features of chemical mass balance，principal component analysis，factor analysis，positive matrix factorization such source apportionment methods are introduced in detail. Meanwhile，the development tendency of source apportionment for fine particulate matter is forecasted.
