根据闽北地区杉木丰产林110块样地的经营密度,应用半峰宽公式计算其合理经营密度。结果表明,最大密度模型的合理经营密度为0.64～0.88,最大密度线模型的合理经营密度为0.62～0.89;两种模型的经营密度经u检验表明没有显著差异;符号检验结果表明,两者的合理经营密度都适用于闽北地区杉木人工林的林分密度管理。
According to the management density of 110 plots of fir plantation in North Fujian, the reasonable operating density was calculated by using the half-width formula. The results showed that the reasonable operation density of the maximum density model was 0.64 ~ 0.88 and that of the maximum density line model was 0.62 ~ 0.89. The operating density of the two models showed no significant difference by u test. The symbol test results showed that the two The reasonable management density is suitable for the stand density management of Chinese fir plantation in northern Fujian.
