Study on Standard Height Curve Model of Masson Pine Planted Forests.

Abstract: In order to forecast accurately height of each diameter class, the relationship between height curve, stand age, site and stand density was analysed using data of sample stand and permanent sample plot. The result sindicated close relations between height curve and stand age, site. Height curve moved up-right with the increase of stand age and site, and was not related to stand density. With a view to solving existing problems, the author introduced the site and stand age into the height curve model, establishing 13 new height curve models by means o f double regression. Height curve models were imitated viaiterative method using data of 200 sample plots. By comparison, Richards function with biology meaning was selected as the standard model, and the standard heigt curve equation of masson pine plantations in Guizhou was suggested. The forecast equation proved applicable in the regions.
