中文摘要	河北围场县处于京津风沙源治理区,森林成为京津抵御沙尘暴侵袭的绿色屏障.对该县Landsat TM遥感数据进行了处理,分别利用标准差植被指数(NDVI)和非监督分类提取出1987年和2000年森林分布,结果表明:1987～2000年林地总体上减少但变幅不大,减少的林地主要分布在西部御道口牧场沙化较严重的地区;增加的林地主要分布在东部轻度和中度土壤侵蚀的坝下冀北山地.同时,对森林变化驱动机制进行了分析,论述了森林变化的生态环境效应.
英文摘要	Weichang county in Hebei province is located in controlling area of wind and sand source in Beijing and Tianjin. Forest becomes a greenbarrier to resist sandstorm attack. After the remote sensing data preprocessing, forest distribution were extracted respectively from 1987 ami 2000 images by using NDVI and unsupervised classification. Forestland reduced from 1997 to 2000 and the change was not great. Reduced forestland was mainly distributed in Yudaokou pasture in the west, resulting in more serious desertification. Increased (brestland was mainly distributed in the east, the mountainous area in die northern Hebei with slight and middle degree of soil erosion. Driving force of forest change was analyzed and ecological effect resulting from forest change was described.
