摘要
根据固定标准地调查材料，对中幼林杉木胸高断面积及胸径的自然生长进行分析表明：不同立地指数的杉木林分，其断面积及胸径自然生长是一组扩展的Ｒｉｃｈａｒｄｓ函数的多形曲线。
Investigation on fixed sample plot and analysis on cross-sectional area and natural D.B. H. growth of young and mid-age Cunninghamia lanceolata forest indicated that stand with different site index, cross-sectional area and natural D. B. H growth were multiform curves of extension of Richards function.
