%X We used the spatially explicit forest landscape model (LANDIS) to stimulate the long-term forest landscape change under pest disturbances with different intensities.The species area percents and age structures of Larch and White Birch and the species patterns were derived by using APACK. Results indicate that the pest disturbances led to a decrease in area percent of Larch cohorts and an increase in area percent of White Birch cohorts.The disturbances also led to a decrease in area of over-mature and mature cohorts of Larch and an increase in area of all age-cohorts of White Birch.We conclude that forest pest reduces the stability of forest ecosystem and leads to landscape fragmentation to some extent.
