摘  要：
为探索微立地对脂松幼林生长的影响,采用较小尺度,测定与单株林木生长空间相关的土壤物理性质,并通过方差分析方法分析了脂松幼林期间的树高和胸径的生长量。结果表明:不同微立地类型上土壤物理性质差异显著,微立地地形因子对脂松幼林的树高生长和胸径生长都有显著影响,其中凹地形和伐桩对脂松的树高和胸径的生长是负影响,而且与普通地形上的林木长势差异显著;凸地形对脂松的树高和胸径的生长是正影响,但与普通地形上的林木长势差异不显著。

摘  要：
A study was conducted to determine the soil physical properties on microsites which are correlated with the individual tree growth in order to discuss the effect of the microsite on the growth of young red pine(Pinus resinosa)stand.The increments of tree height and diameter at breast height of red pine were analysed by variance analysis.Results indicate that the differences in the soil physical properties between different microsites are remarkable.Microscale landform indexes have significant effects on the growth of tree height and diameter at breast height of red pine.Hollow land and stump show negative effects and the growth of the trees on this microsites is obviously different from that on the general sites,while protruding land exhibits positive effects and there is an insignificant difference in tree growth between protruding land and general sites.
