Abstract:: Forest litters play an important role in forestry ecological system.The essay discussed forest litters of main plants in Datong county,Qinghai province.Three subjects were discussed,which is preserving capacity,losing water trait and effective holding quantity of rainfall.The results show: (1) The annual accumulation of different forest litter is about 5.85～34.16t/hm²,and the account of natural spruce is higher than others,the account of northern larch is the least.(2) The containing water quantity of forest litters dramatically dropped within 1 or 2 hours and then slowed down.It illustrates forest litters can reach natural containing water quantity with wetness of litters declining.(3) Comparing effective holding capacity of this three types of forest litters,the research found natural spruce was the best,and sea buckthorn followed,northern larch was the last.
