【摘要】 为研究弃渣场治理前后土壤的渗透性及贮水特征,以自然裸坡为对照,分别对采取拦挡植被恢复措施和未采取拦挡植被措施的弃渣场坡面土壤的入渗与贮水特征进行了研究。结果表明:1)弃渣场坡面采取拦挡及植被恢复措施后土壤的饱和贮水量、最大滞留贮水量、最大吸持贮水量分别是未采取拦挡及植被恢复措施的1.18、1.53和1.04倍,土壤的初始入渗率、稳渗率、平均渗透率和渗透总量分别是1.3倍、1.28倍、1.29倍和1.27倍;2)坡位对土壤贮水及渗透性的影响明显,治理后表现为坡上>坡中>坡下的规律,而未治理及裸坡均表现出与之相反的规律;3)土壤渗透性与土壤总孔隙度、非毛管孔隙、毛管孔隙、土壤容重显著或极显著相关;4)对土壤入渗过程模拟得出Horton模型是用于描述该流域土壤入渗过程的最优模型。更多还原

【Abstract】 To study the characteristics of Soil water holding capacities and infiltration characteristics before and after its dumping sites,Soil water holding capacities and infiltration characteristics of dumping sites were studied with measures to implement plant and landang or Plants and landang measures not implemented,We used bare slop as a control.The results indicated that:① Soil saturated water storage,water-holding capacity of noncapillary porosity,water- holding of capacity porosity,initial infiltration rate,average infiltration rate,stable infiltration rate and accumulate infiltration of measures to implement plant and landang were landang measures not implemented times 1.18 、 1.53 、 1.04 、 1.3、 1.28 、 1.29、1.27.② The influence of slope position on the infiltration rate had obvious regularity,The measures to implement plant was the regularity of upslope > middle slope> down slope,however,there existed a contrary tendency for landang measures not implemented.③ The closely relative factors to soil water infiltration properties were picked out,which included total porosity,noncapillary porosity,capillary porosity,soil bulk density.④ Horton model was the best one to describe the soil infiltration processes of this area.更多还原
