非毛管孔隙

结果表明，研究区人工林土壤团聚体稳定性较差、非毛管孔隙数量少；

The results showed that soil aggregates are very unwaterstable and there are very little non-capillary pores ;

除荒地外，其它三种模式同一土层土壤的毛管孔隙、非毛管孔隙及总孔隙均是雨季大于旱季。

In addition to the wasteland , capillary pore , non-capillary pore and total porosity of the other three modes in the same soil is the rainy season higher than the dry season . 2 .

炼山迹地土壤容重比杉木林地增加10%，非毛管孔隙、自然含水量和毛管持水量分别下降61%、48%和26%。

In controlled burning stand , soil bulk density increased by 10 % , while soil non-capillary porosity , natural water capacity and capillary moisture capacity decreased by 61 % , 48 % and 26 % , respectively .

结果表明：（1）泥炭施入能够使坪床基质的渗透性降低，总孔隙度和毛管孔隙度增大，毛管孔隙和非毛管孔隙的比例趋于平衡，有利于提高坪床保水能力和通气性。

The result shows : ( 1 ) Peat could decrease the permeability of root zone media decrease , increase the total porosity and capillary porosity , and balance the capillary porosity and non - capillary porosity became .

土壤毛管孔隙、非毛管孔隙及总孔隙呈现的规律为：农耕地最大，荒地最小，荒地与其它三种模式的大小差异显著，剑麻与剑麻×花椒地差异不显著。

The rules on soil capillary pore , non-capillary pore and total porosity rendering : farmland is highest , wasteland is the lowest , wasteland significantly varies in the other three modes , little difference between sisal and sisal × pepper .

结果表明：（1）森林生态系统综合水源涵养能力中土壤系统和枯落物系统涵养水源量占了绝大部分比例，土壤非毛管孔隙对森林水源涵养能力具有决定性作用。

The results of study express : ( 1 ) Among comprehensive water retention capacity of forest ecosystem , water retentions in soil and litter layers account for the most proportion . Soil non-capillary porosity plays the key role in the determination of water retention capacity of ecosystem .
