| Abstract: | The main biochemicals (such as lignin, protein, cellulose, sugar, starch, chlorophyll and water) of vegetation are directly
or indirectly involved in major ecological processes, such as the functions of terrestrial ecosystems (i.e., nutrient-cycling
processes, primary production, and decomposition). Remote sensing techniques provide a very convenient way of data acquisition
capable of covering a large area several times during one season, so it can play a unique and essential role provided that
we can relate remote sensing measurements to the biochemical characteristics of the Earth surface in a reliable and operational
way. The application of remote sensing techniques for the estimation of canopy biochemicals was reviewed. Three methods of
estimating biochemical concentrations of vegetation were included in this paper: index, stepwise multiple linear regression,
and stepwise multiple linear regression based on a model of the forest crown. In addition, the vitality and potential applying
value are stressed. |
