| 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。

| Abstract: | 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 ARCGIS.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 ... |
