    Abstract:

    In order to exploring litter yield and dynamic changes of monsoon evergreen broad-leaved forest,we set collecting nets to gather litter at regular intervals in different restoration stages and analyzed litter yield.The results showed that:(1)The annual litter yield was between 8 133.1 and 8 798.3 kg/hm2 in different restoration stages of the communities,and the annual litter yield from high to low is 30a communityCastanopsis echidnocarpa,Castanopsis hystrix,and Schima wallichii,the highest annual leaf litter was the C.echidnocarpa for all communities (53.93% for 30a community,47.83% for 40a community and 28.32% in old growth forest),the second was S.wallichii (8.45% for 30a community,10.71% for 40a community and 31.69% for old growth forest),the lowest was the C.hystrix (6.1% for 30a community,7.53% for 40a community and 6.36% for old growth forest).The leaf litter dynamic change of C.echidnocarpa was unimodal curve for restoration communities,but it was polymodal curve for old growth forest;the form of leaf litter of S.wallichii was unimodal curve for all communities;the leaf litter dynamic change of C.hystrix was unimodal curve for 30a community and old growth forest,but it was polymodal curve for 40a community.
