| 摘 要： | 以紫色岩上区出露最广的三种紫色岩组及其相应的土壤为重点，研究了紫色岩土的物质成分、风化和水理等性质与水土流失的关系，揭示了紫色土侵蚀区侵蚀模数大、输移小、母质侵蚀突出的本质。在此基础上，对紫色土区水土保持治理工作，提出了相应的建议

| Abstract: | The relations between the characteristics of purple soils ,such as their compositions ,weathe-ring, hydromechanics, etc. ,and water and soil losses were studied with an emphasis on the three mostextensively emergent kinds of purple rocks and soils.It is revealed that the purple soil ercaion area Possesses those essential properties,i.e. ,big erosion moduli ,small delivery ratios and severe parentmaterial erosions. Based on this study , some suggestions on water and soil conservation measures areproposed. |

| Keywords: | purple soil water and soil los erosion modulus delivery ratio slaking |
