Abstract: This paper summarizes the experiences of Guangxi Daguishan forest farm in establishing a high efficient and rational structured multi-laver and multi-species shelterbelt network.The ecological effects of this network in preventing forest fire and pest infestation,in promoting large-area fOrest growth, better cycling and sustained cropping,and in creating favorable ecological environment for forest regeneration are discussed.

Key words: scenario, land use change, spatial model, landscape, biomass density, forest age.
