Abstract: The decomposition process of fallen leaves of the semi-deciduous monsoon forest and the mountain rain forest had been studied with net bags and covers made by nylon threads at Jianfengling,Hainan Island.Through two-year observation,decomposed loss rates of the fallen leaves are 92.27%,78.01% and 99.08%,95.41% respectively.The decomposed velocity of fallen leaves using the cover method is faster than that of the bag one,likewise,the decomposed velocity of the semi-deciduous monsoon forest is faster than that of the mountain rain forest.The decomposition rate "K" values is 2.172,1.578 and 1.596,0.836,correspondingly.Full decomposition may need two and six years,respectively.The removal order of the elements on the decomposition process of the semi-deciduous monsoon forest and mountain rain forest fallen leaves are as follows,KCaNaMgNCPAlFeSiKCaMgNaONPAlSiFeThe decomposition of the litter fall which is an important process and way of material cycle and soil nutrients input into the forest ecosystem.This research has an important academic meaning and applying value on the structure,function and management of the tropical forest ecosystem.
