The results show that: VBSI may decrease the error of vegetation fraction resulted from the area of image shadow, and the error is 50% less than that from NDVI.
研究结果表明：VBSI在估算山区的植被覆盖信息上可以降低影像阴影信息的干扰，总体误差是归一化植被指数NDVI 的50%；
The difference between NDVI and EVI is larger as vegetation coverage increases.
NDVI与EVI值的差异随着植被覆盖度的增加而增大。
The study extracted the image of the distribution of forest landscape and overlay with forest coverage map. Broadleaf forest, conifer forest , mixed forest and shurb are classified with NDVI.
本研究中提取北京山区的森林景观分布，叠合植被覆盖图，结合NDVI图，将其分为阔叶林、针叶林、灌草和混交林。
