摘要：

Techniques are developed to estimate stand leaf area index using high-resolution airborne spectral imagery. Leaf area index on 8 m radius plots was found to be strongly related to the normalized ratio of wavelengths in the red (674-687 nm) and near infrared (751-755 nm) part of the spectrum. Data from 17 stands were used. Leaf area index estimates included both the overstory (Douglas-fir, Pseudotsuga menziesii Mirb. (Franco)) and the understory (salal, Gaultheria shallon Pursh) over a range of stem densities.
