A new well-behaved diameter distribution function for unthinned Chinese fir (Cunninghamia lanceolata) plantations in southern China

The objective of this study was to introduce a new high-performance diameter distribution function. The long-term repeated measurement data sets, consisted of 150 diameter frequency distributions from Chinese fir (Cunninghamia lanceolata) plantations in the southern China, were used.

description	The objective of this study was to introduce a new high-performance diameter distribution function. The long-term repeated measurement data sets, consisted of 150 diameter frequency distributions from Chinese fir (Cunninghamia lanceolata) plantations in the southern China, were used. R distribution had presented a more accurate simulation than three-parametric Weibull function. The parameters p, q and r of R distribution proved to be its scale, location and shape parameters, and have the deep relationship with stand-level variables, which means that the parameters of R distribution have the good biological interpretation. The main distribution range of inflection points for the cumulative diameter distribution of Chinese fir plantations was 0.4~0.6.
