| 摘 要： | 文章以湿地松7,8,13年生初植密度和19年生间伐强度试验林胸高形数、高径比和正形率系列为干形指标,研究了林分密度对湿地松林木干形的影响规律。结果表明,不同初植密度间林木胸高形数的差异不显著,高径比则存在显著差异;间伐强度对胸高形数和胸高形率的影响不显著,但以中度间伐(伐去株数35.7%)林木干形相对较为饱满。

| Abstract: | Based on the data of slash pine planting density in age 7,8,13 and thinning intensity in age 19,breast-height form-factor,H/DBH and normal form quotient were analyzed,so as to study the effect of stand density on stem form.The results showed that there were significant variations at breast-height form-factor between different planting density rather than H/DBH.Though the variations of breast-height form-factor and breast-height form-quotient between different thinning intensity were not significant,the moderate thinning improved stem form to a certain extent. |
