Study on the Standard Table of Pinus massoniana Plantation in Youxi County
Li Zhaomei;Youxi State-owned Forest farm;
In the standard stand of canopy density above 0.8 in Pinus massoniana plantation in Youxi County,the average diameter at breast height,average height,dominant height,volume per unit area,chest area and number oftrees were investigated and determined. With high stand advantage as an auxiliary variable,and the stand per hect-are of the stand as the dependent variable,the standard stand volume model was established using the immune evolutionary algorithm. Taking the forest stand height as the dependent variable and the forest stand high as the auxiliary variable,a suitable forest stand height model was established through multi-equation fitting comparison. Based onthis,the standard table of the Pinus massoniana plantation in Youxi County was compiled. The scientific basis for thedetermination of forest density and stock volume in resource inventory is provided.
