摘要: 在RS和GIS技术支持下, 使用1990-2005年三期遥感影像数据作为信息源, 获取怀柔水库流域近15年景观格局特征数据, 利用马尔可夫模型深入分析怀柔水库流域景观动态转化特征。分析表明:灌木林和阔叶林是流域的主要景观类型, 流域景观组分相对稳定;阔叶林、针叶林、混交林的面积所占比例呈上升趋势, 灌木林面积下降趋势明显;其他土地类型面积在这15年内一直逐年减少;农田面积总体变化不大。

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
