Derivation of Leaf‐Area Index from Quality of Light on the Forest Floor
Ecology · 1969 · Vol. 50(4) · pp. 663–666
Abstract
Leaf—area index of a forest can be measured by determining the ratio of light at 800 μm to that at 675 μm on the forest floor. It is based on the principle that leaves absorb relatively more red than infrared light, and therefore, the more leaves that are present in the canopy, the greater will be the ratio.
