| 摘 要： | 通过森林土壤渗透系数试验,应用数量化理论(Ⅰ)建立了森林土壤渗透系数的数学模型。影响森林土壤渗透系数的第一位因子是土壤质地与容重的交互作用,其次为土壤质地、容重、含根量、容重与含根量的交互作用。数量化理论(Ⅰ)可用于大面积森林土壤渗透系数的估算,其精度较高。

| Abstract: | We collected 21 soil samples from different foresr soil in Chang Bai Mountain and built a mathematical model on infiltration coefficient of forest soil under saturation with theory(1) of quantification. Results are following.1.The mathematical model about infilfration coefficient of forest soil under satyration is drawn;2.First factor, which affects the infiltration is the interaction between soil texture and soil unit weight.According to the importance of other factors, we hace soil texture, unit weight, root quantity in soil and interaction retween the last two;3.Theory(1) of quantification could be used easily with higher pricision for estimating infiltration ofefficient of froest soil under saturation. |
