This paper dealt with the new method which was considered to be useful for the purpose of quantitative description and analysis of existing state of forest ecosystems. 1) The experimental formulae proposed by BEST A. C.1), 2) about 20 years ago (Equation 1, 2 and 3) were introduced, and then, the problems arised at point of X→Xmax in equation (3) were scrutinized. [Figure omitted] 2) Intending to develop the new method for quantitative analysis of woodland ecosystems, a trial of expansion of the BEST's FUNCTION was made. In some natural and artificial forest ecosystems, the BEST's FUNCTION could be rewrited as following, [Figure omitted] 3) The properties of equation (4) and (5) were discussed based on mathematical and biological points of views. 4) The properties of α, β and n, which indicated the three parameters in equation (4) and (5), were investigated. 5) The advantages of equation (4) and (5) as the new method for quantitative analysis of forest ecosystems were suggested.
