摘要
利用分布于延边地区不同立地条件下的391 株天然赤松解析木资料,分析回归了赤松根径与立木材积的相关关系,并运用拟合不足检验法,确定了最佳模型.
Based on the analytic parameter of 391 natural Japanese red pine which is in different condition in Yanbian Area,through regression analysis on the relation of root diameter and stand tree volume,we confirmed the best model by using the lack of fit test method.
