| 摘 要： | 采用较小立地尺度对土壤水分物理性质的变化及与水曲柳生长的关系进行研究.结果表明,除传统尺度立地上土壤水分-物理性质存在较大差异外,该尺度立地内部微立地间亦存在较大的变化,一些指标如非毛管孔隙度、土壤通气度和土壤渗透系数等在微立地间的变化甚至超出立地间的变化.土壤水分-物理性质的差异,使得不同微立地间水曲柳生长存在较大差异,同一立地内不同微立地间林木生长差异明显高于不同立地间的差异.土壤水分-物理性质及林木生长受到局部地段微立地的影响.微立地的研究对进一步实现适地适树具有重要意义.

| Abstract: | Soil microsite plays an important role in the regeneration, seedling survival, and individual growth of trees.This paper studied the relationship between soil microsite moisture physical properties and Fraxinus mandshurica growth.Variation was found not only among different sites in traditional scale, but also among different microsites.Some variations of soil properties among different microsite were greater than those among different sites. The growth of Fraxinus mandshurica varied greatly among different microsites.Microsites affected most soil moisture physical properties and tree growth.The study demonstrated the importance of matching trees to the proper microsite on the growth of plantation stand. |
