非毛管孔隙 meaning in English
non capillary pores
Examples
- It was showed that forest with good structure could improve the soil noncapillary porosity and water conversation function , and it was implied that forest with rational structure stored rainfall and surface runoff quickly
表明具有良好结构的林分,可有效改善土壤非毛管孔隙度和滞留贮水功能,从而有效地提高对降雨的快速贮存以及蓄洪与涵养水源作用。 - Compared to stipa bungeana grassland and fallow ground , the volume weight was smaller , total porosity and capillary porosity were higher , but non - capillary porosity was lower . 2 . achnatherum splendens height increased slow in the initial stages , fast from june to august and slow again after that
芨芨草草地土壤容重较本氏针茅草地和裸地小,各层的总孔隙度和毛管孔隙度明显高于本氏针茅草地和裸地,但非毛管孔隙度较本氏针茅草地和裸地低。 - When soil antecedent condition is dry and the initial rainfall intensity is high , peak surface runoff also considerably lag behind that of rainfall , because of the formation of temporary relative impermeable top layer ; b ) surface runoff is controlled primarily by infiltration - excess runoff mechanism under unsaturated condition ; the major fraction of surface runoff are dominated by saturated infiltration - excess runoff response , only a small fraction by return flow mechanism when soil is saturated ; c ) subsurface flow is dominated by saturated runoff mechanism , and the duration of subsurface post the rainfall end is dependent upon rather the soil properties than the rainfall characteristics ; d ) subsurface flow intensity in cultivated soil layer ( 0 ~ 20cm ) is high up to 35mm / h when rainfall intensity is up to 120mm / h , indicating the existing of macropores and pipe flow in cultivated layer
2 )耕作制下紫色土的产流主要机制是: 1 )当雨前土壤含水量未达到饱和状态时,表面产流起始时间有明显滞后现象,这与紫色土的快吸水性和较多非毛管孔隙密切相关;当雨前土壤较干燥,降雨初期雨强较大时,易形成临时相对不透水表层,表面产流峰也有明显滞后现象。 2 )表面径流的产流方式主要是超渗产流,当土壤达到饱和状态后,有四川大学博士学位论文小部分回归流发生,但主要是饱和超渗产流发生,因为紫色土的相对不透水层和其它透水障碍层不明显。 3 )壤中流主要是饱和产流,与降雨过程有明显的滞后,而且雨停后的壤中流产流历时与降雨特征无关。 - On the other hand for four main vegetation typies , which are picea crassifolia , forests sabina przewalskii forests , bushes and pastureland , whose soil permeability function was analyzed from angle of its physics , capacity of water , storing water in it . the results show as follow : permeability function of soil is controlled by quality of soil hole . the quality and quantity of soil hole under picea crassifolia forests are the best , and the permeability also is the best
另外,从土壤物理性质、蓄水量、贮水量等角度对祁连山苔藓云杉林、祁连圆柏林、亚高山灌丛林、牧坡草地4种主要植被类型的土壤渗透功能进行分析,结果表明:土壤的渗透功能主要由土壤非毛管孔隙度的质和量决定的,苔藓云杉林土壤非毛管孔隙度的质和量最好,它的渗透也最好;虽然亚高山灌丛林的渗透功能次之,但由于它所处的位置和面积大,现实贮水量在祁连山四种主要植被类型中最大。 - The fractal dimension of the mixed forests were lower than the pure forests and grassland , and the soil weight diameter of the mixed forests were higher than the pure forests and grassland , which indicated that the mixed forest had best soil structure property in stability infiltration and water - holding ; the soil total porosity and the soil noncapillary porosity were different greatly between forest types , but the soil capillary porosity had little differ
混交林分分形维数均低于单纯林与荒草地,土壤重量平均直径均高于单纯林与荒草坡,说明混交林土壤结构稳定性最好,土壤通透性较好,具有较高的水土保持功能;不同林分类型之间,土壤总孔隙度与非毛管孔隙度差异较大,而毛管孔隙度的差别较小。
