54 cm2/min, and was influenced by soil moisture, soil particles size distribution, soil bulk density and capillary porosity.
５４ｃｍ２／ｍｉｎ之间，并受土壤含水量、容重和毛管孔隙度的影响，而毛管孔隙度大小是影响非饱和土壤水扩散率的首要因素。
The soil non-capillary porosity of B.
结果表明:与白桦林相比,油松林对林内小气候的调控能力更强,但对土壤温度的调控能力低于白桦林;白桦林土壤的非毛管孔隙度高于油松林,且白桦林枯落物分解速度快,所以孔隙、养分条件优于油松林;白桦林单位枯落物的最大持水量高于油松林,但油松林枯落物含量高,所以油松林枯落物持水能力高于白桦林。
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.
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。
