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。
I have been in africa before and those countries i was in surprised me too , but this surprised me even more . south africa is really modernized , really too modernized . well , at least here it is a mini - jungle so those of you who expected africa to be a jungle won t feel too disappointed 我以前也来过非洲,我去过的那些国家也让我很惊讶,不过这里更让我惊讶,南非真的很现代化,太现代化了,还好至少这里是一个迷你丛林,对那些认为非洲都是丛林的人,至少不会觉得太失望。
