| 摘 要： | 为了深入研究土石混合介质土壤侵蚀过程机理,加快开发建设项目水土流失的预测与预报,采用改进的原状土水槽冲刷法,研究了露天矿排土场土壤理化性质与土壤抗冲性的关系。结果表明:土壤抗冲指数与容重之间呈显著的负相关,与总孔隙度和毛管孔隙度之间呈极显著正相关,与砂粒含量呈极显著负相关,与粘粒含量呈显著负相关,与大于0.25 mm水稳性团聚体含量呈显著正相关,与2~1 mm水稳性团聚体含量和1~0.5 mm水稳性团聚体含量呈显著负相关,与土壤初渗率和稳渗率呈显著正相关,与有机质、全氮和全钾含量呈显著相关关系。该研究可为开发建设项目土壤侵蚀的预测建模提供理论依据。

| Abstract: | In order to study the process of earth-rock mixed media of soil erosion mechanism,accelerating the development of construction projects,soil erosion prediction and forecasting,using an improved water tank undisturbed soil erosion method to study the open pit mine waste dump of physical and chemical properties of soil and soil erosion resistance relationship.The results showed that scour the soil between the index and bulk density was significantly negatively correlated with the total porosity and capillary ... |
