摘　　要：通过对26株巴山松解析木资料的统计整理,并对其生长量进行分析,利用各种"经验方程"和"过程方程"对其拟合,发现Gompertz生长曲线对巴山松生长情况拟合较好,拟合的胸径、树高、材积方程为:Y=Kê[-1.246398491ê(1.957708132X)];Y=Kê[-1.293557657ê(-0.01217368X)];Y=Kê[-2.402839ê(-0.01084X)]。研究发现,巴山松在较好的立地条件和与其适应的环境下能较好地生长,其数量成熟龄较大,达到109 a,是培育大径阶材的理想树种。The data of 26 analytical woods of Pinus henryi were processed statistically, the growth of the wood was analyzed. Different ＂empirical equation＂ and ＂process equation＂. The results showed that the Curve of Gompertz was suit able to the growth situation, and the fitting equation of diameter at breast height, tree height, and timber volume were in turn： Y=K^e[-1. 246 398 491^e（1. 957 708 132X）]; Y=K^e [-1.293 557657^e（-0.012 173 68X）];Y=K^e[-2.402839^e（-0.01084X}]. It was found thatP, henryi could grow well under the better site and adaptation environment condition. The quantity mature age appeared a little bit later and reached in 109 year. It is an ideal tree species to cultivate the big diameter step material.
