| 摘 要： | 以2002年全省林地土壤调查样本中的土壤非毛管孔隙度资料为研究对象,讨论了不同的纬度、母岩、海拔、树种、坡度、坡向、坡位和土层厚度等对土壤非毛管孔隙度的影响。结果表明:不同的纬度、母岩、海拔、树种、坡度的土壤非毛管孔隙度分布有明显规律性,而坡向、坡位和土层厚度等对土壤非毛管孔隙度的分布影响不大。

| Abstract: | Effects of six factors, included latitude, parent rock, elevation, trees species, slope gradient, exposure of slope, slope location , and thickness of soil, on non-capillary porosity of soil were investigated based on the samples of woodland in Guangdong province in 2002. Results indicated that: Non-capillary porosity show strong rules along with the changes of latitude, parent rock, elevation, tree species, but direction of slope, location of slope, and thickness of soil have little effect on non-capillary porosity. |
