Abstract: Sampling plot researches revealed significant effect of forest litter on soil fertility, soil conservation,water regulation and soil temperature and humidity. It is also found that when Chinese arborvitae is property mixed with Chinese pine, it can remedy the defects of pure stands and improve the overall ecological benefits.Therefore Chinese pine and Chinese arborvitae mixed forests are considered to be widely prospective in mountainous areas end their litters should be strongly preserved.
