  6. Because these factors make change more often, soil time space variability is more bigger. the relationship of single factor between soil water infiltration capacities and certain influencing factor could be established quantitatively by means of soil water infiltration tests in indoor, there is negative correlation relation between soil water infiltration capacities and soil structure. there is negative correlation relation in high grit content and low physical clay content soil, and second - degree polynomial relation in high physical clay content junk structural soil between soil water infiltration capacities and soil moisture

    由於這些因素在時刻發生變化，使得土壤的時空變異性較大，只能用室內土壤水分入滲試驗來定量確定土壤水分入滲能力與某些影響因素之間的單因子相關關系，土壤水分入滲能力與土壤結構之間呈負相關關系，土壤水分入滲能力與土壤含水量之間在土壤砂粒含量高，物理性粘粒含量低的無結構土壤中呈負相關關系，在物理性粘粒含量高的團粒結構土壤中呈二次多項式關系。

  9. Gradually, with the more and more transpiration of the vegetation, and with the reduction of the deep soil moisture, in the end, a kind of balance of soil moisture will appeared and be kept for ever between the precipitation and the transpiration of vegetation, and the manual sand - fixing vegetation will be transformed consequently into its natural climax stage completely, in which the dominant plant is leymus secalimus, and in which the plant species richness is not too low, but the plant species evenness is the lowest

    設置機械沙障和生物沙障的初期，植物的物種豐富度、物種均勻度會有一個暫時的提高；但是在人工固沙植被的發育盛期，物種豐富度會降低；隨植物群落蒸騰耗水量的不斷增大，人工植被不斷地衰退，最後發展到賴草土壤頂極群落，此時的物種豐富度並不低，但是物種均勻度很低。
