    研究結果表明,與對照ck1 ,相比,秸稈覆蓋可使總孔隙度增加2 . 88 % ~ 5 . 76 % ,容重降低1 . 86 % ~ 3 . 73 % ,並且各生育期覆蓋處理的城含量均比對照,並且秸稈覆蓋還田對促進團粒結構形成具有較大作用,改善了坡通和保保肥;同時秸稈覆蓋還田使有機質、全氮、速效氮、速效磷、速效鉀得到明顯提,從而培肥地力。
  3. The research result of the paper indicates that utilizing manual soil dealing with rainwater can reach better depurating effect by reasonable designing and controling. in practical project, especially in the condition of soil with badly penetrating ability and lower groundwater level, can adopt about one meter deepness manual soil laying on the greenbelt and can also design special manual soil depurating equipment around building to dealing with rainwater, which not only assures depurating effect but also saves occupying area and improves environment

    本論文的研究結果表明,經合理設計控制,利用人工加人細砂的層處理雨徑流,可達到較好的處理效果,實際工程中,尤其是在很差,地下位較等情況下,可以在綠地表層採用lm左右的人工層, 『也可在建築物附近設計專門的人工凈化裝置來處理雨徑流,既可保證處理效果,又可節省佔地和改善環境。
  4. 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,從物理質、蓄量、貯量等角度對祁連山苔蘚雲杉林、祁連圓柏林、亞山灌叢林、牧坡草地4種主要植被類型的功能進行分析,結果表明:的滲功能主要由非毛管孔隙度的質和量決定的,苔蘚雲杉林非毛管孔隙度的質和量最好,它的滲也最好;雖然亞山灌叢林的滲功能次之,但由於它所處的位置和面積大,現實貯量在祁連山四種主要植被類型中最大。
