The broad sense concept and calculation methods of tree crown overlap
The broad sense overlap concept and types of tree crown overlap were defined in the paper through analyzing function between the factors of tree crown overlap. The formulas of overlap area and overlap rate were derived from definite integral form. At the same time, many formulas were acquired while the projective figures of tree crown were circle. Application ways of these formulae were illustrated with a concrete caculation process.
