摘要:植被覆盖度是一个十分重要的生态学参数,对于全球变化和监测研究具有重要意义。本文基于像元二分模型,利用归一化植被指数NDVI,对怀柔区1992年和2004年植被覆盖度进行了监测,并对十几年来的植被覆盖变化情况进行了统计分析。结果表明,全区植被覆盖整体呈上升趋势,但存在区域间的不平衡现象。
Vegetation fraction is a very important index to the vegetation coverage on the land surface and is used in many aspects in one of the input parameters. Based on the dimidiate pixel model and NDVI, this paper estimated the vegetation fraction in Huairou District by remote sensing. In the total, the vegetation coverage wass increased during the passed 12 years. But the change was imbalance among different areas.
