摘　　要：以红松、鱼鳞云杉和臭冷杉为研究对象,对解析木数据进行分析,比较和研究其树高生长过程。方差分析结果表明:三个树种的树高生长量存在显著差异,其中:树高总生长量P-value为6.05E-05,树高平均生长量为1.23E-04,树高连年生长量为3.39E-02。树龄在100 a以内的臭冷杉树高生长量最大,鱼鳞云杉次之,红松最小。Pinus koraiensis, Picea jezoewsis and Abies nephrolepis had been taken as the research objects, height growth process was compared and datas of analytic were analyzed. The results of ANOVA showed that there were significant differences in the height incremem between the three species. Among them, the P - value of the total height increment was 6.05E - 05, mean height increment was 1.23E - 04, current annual increment was 3.39E -02. In 100 years old, Abies nephrolepis had the most height increment and Piceajezoensis took the second place, P/nus koraiensis was the least.
