Abstract

Abstract: Based on RS and G IS techniques and using remote sensing images of 1990-2005 period as a source, the landscape dynamic characteristics of Huairou Reservoir w atershed during the 1990-2005 period were collected and analyzed by ARCGIS.The development and transforming of landscape ty pes of Huairou Reservoir watershed were simulated and comprehended with Markov model.And the resultshowed that landscape pattern of watershed formed mostly of shrub forest and broad leaved forest was comparatively steady.The proportion of area of broad leaved forest, boreal forest and mixed plantations was enlarged, and the area of shrub forest was descended.The area of other landscape type decreased in past 15 years, but there was no big change in farmland type.

Key words: landscape dynamics, markov model, Huairou Reservoir, GIS
