Principles of Statistical Phytoactinometry

To obtain adequate knowledge on radiation transfer in vegetation canopies and to estimate its integral radiation parameters reliably requires an improvement of the available theories and experimental techniques. Along with this, the development of phytoactinometry along classical lines frequently leaves a number of principal problems unsolved. Fundamental among them is the question regarding theories based on the optical turbidity hypothesis and classical transfer equation. Of no less importance is the question as to the possibilities and the role of Monte Carlo models developed widely in the last few years. It is thought that progress in establishing a better-grounded position on these problems could be achieved by the introduction and use of the random field concepts and statistical theory.
