Based on the field study of forest littlefall collection, this paper dealt with carbon dynamics of forest litter under six landuse types in the subtropical China in 2004. The results showed that: (1) Carbon amount of litterfall of the naturally secondly stands and masson pines formed doublepeak in Mar.and Jun., Feb.and Apr., respectively, while Chinese fir stand, Ph.praecox and moso stand formed singlepeak in Dec., Mar., May and Jun. respectively. (2) Carbon amount of littlefall of the naturally secondly stands was 3.22 t/hm2, the following were Chinese fir stand and masson pines, the extensively and intensively managed moso stand were almost the same, while the least was Ph.praecox stands, which was only 1.39 t/hm2. (3) Components of forest litterfall carbon were mainly composed of leaf, which were among 58.00 % and 73.65 %, while branch, fruit and others occupied less proportion of forest litterfall. (4) The naturally secondly stands had the best ability of improving the soil quality by selffertilization, which meant their ecological function had advantages over other landuse types.
