摘　　要：运用Logistic模型和二维有序样品聚类法分析了西藏巨柏播种苗生长过程,并建立了苗高和地径、生长时间与苗高之间的拟线性回归模型。分析结果显示:各个回归模型的相关系数都达到了显著水平。为科学培育巨柏优质苗木提供了理论依据。Using Logistic model and ordered two-dimensional clustering analysis,the growth process of Cupressus torulosa seedlings were analyzed.And the quasi-linear regression models for the correlations between seedling height and ground diameter,as well as growth time and plant height were established.The analysis results showed that the correlation coefficient of each regression model had reached a significant level.The research provided theoretical basis for the scientific cultivation of good-quality Cupressus torulosa.
