摘　　要：使用1990-2005年3期遥感影像数据作为信息源，通过GIS手段，分析怀柔水库流域近15年土地利用变化特征．利用主成分分析法，综合社会经济统计数据，定量分析怀柔水库流域土地利用变化的驱动力。分析表明：流域内阔叶林、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，农田面积总体变化不大；土地利用变化和经济发展程度密切相关，与人口因素关联度不高。Based on GIS, making remote sensing images of 1990-2005 periods as resource, Land-use characteristics of huairou reservoir watershed during 1990-2005 year were analyzed and combined by ARC- GIS. The development and transforming of land-use of huairou reservoir watershed were comprehended with principal components analysis. And the result showed that 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 farmland had no largely change. Economic development was the major factors affecting land-use in the study district, and population had feebly affected land-use.
