Abstract

Abstract: The annual litter amount of 55 years old Pinus massoniana and Michelia macclurei mixed forest is 6284kg. ha^-1, of which, leaf-litter accounts for 69.5％, 11.2％ higher than that of same years old pure P. massoniana stand. The amount of litter in mixed forest occupies 32.4％ of total in spring, and 19.1％ in summer. That of shrubs and herbs in mixed and pure stands is respectively 3.6 and 18％ of total. Compared with pure stand, mixed forest has a better soil nutrient status, the content of soil organic matter being increased 16.7％.
