Abstract For both watershed management and forest management,it is essential to analyze landscape composed mainly of vegetation,simulate the vegetation succession,and predict future landscape pattern.In this paper,LANDIS,a spatially explicit model for forest landscape disturbance,management,and succession,was firstly applied to simulate secondary forest succession for coming 500 years in a small watershed of Loess Plateau.This simulation results shows: Pinus tabulaeformis Carr.is the dominant species among conifers and Quercus wutaishabcia Mayr is the dominant species among broadleaf arbors.During the coming 500 years’ forest succession simulated with forest landscape LANDIS model,Pinus tabulaeformis Carr.will maintain their dominancy for 430 years and then Quercus wutaishabcia Mayr will usurp the dominion for 70 years.The relative contagion index of broadleaf arbors varied greatly than conifers.The component structure of forest age changes significantly with various spatial pattern of different ages of forest come into being as the year going on.
