total porosity

Soil bulk density is higher, total porosity and field capacity are small.

容重较大，孔度和田间持水量小；

An amendment should decrease bulk density, increase total porosity, and increase water and air content.

改良剂能降低堆积密度, 增加总孔隙度, 增加水和空气的含量.

The result showed that the sequence of the improvement of different land use to soil water-stable aggregate and total porosity is natural grass land forest land shrub land cropland.

结果表明，不同土地利用方式对土壤水稳性团聚体和总孔隙度的改善作用的大小顺序为草地有林地灌木林地耕地。

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.

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。

Shady soil organic matter 、 total porosity 、 capillary porosity and non-capillary porosity are greater than sunny; Shady soil bulk density is greater than sunny; different slope positions of soil properties showed different variation. ( 3) The biggest soil bulk density was at gully bottom.

阴坡的土壤有机质、总孔隙度、毛管孔隙度和非毛管孔隙度均大于阳坡；阴坡的土壤容重小于阳坡；（3）不同坡位的土壤理化性质表现出不同的变化规律。

According to tests and analysis, the relationship of effective porosity and total porosity, permeability coefficient and porosity of porous concrete are adduced.

通过试验与分析，给出多孔混凝土有效空隙率和全空隙率，及渗透系数与空隙率的关系；
