Abstract: A long-term and stationary observation on litter production of 5 forest types which distribute widey and are representative in subtropical zone in China was made. The results show that the annual litter production of various stands was different, the evergreen broadleaved forest was maximum (7.99t/ha) and Cunning hamia lanceolata forest was minimum (4.25t/ha). As a given forest type, the litter fraction had a certain rate, the percentage of leaf fraction is more steady than others. In Quercus forest, leaf fraction was 76% of annual total litterfall and C. lanceolata forest only was 51%. The litter production of forest varied with stands, the dynamic pattern of litterfall was determined by the genetic characteristics of species and the stand condition, the regression equations between litter production and climatic factors were derived.
