| 摘 要： | 本文用人工模拟降雨法和田间实测法对比研究了我国亚热带七种代表性土壤的可蚀性，结果表明，两种方法测得的土壤可蚀性Ｋ值都以红砂岩土发育的（耕作）铝质湿润淋溶土和紫色砂页发育的紫色湿润雏形为最高，最低的是第四纪红色粘土发育的红色湿润新成土，本文还对每个供试土壤分别建立了这两种条件下求得Ｋ值间的定量关系，为今后利用人工模拟降雨试验开展各种研究提供了基础。

| Abstract: | Soil erodibility factor K of seven representative soil types in subtropical China was studied using field plots under rainfall simulator and natural rainfall respectively.The results showed that soil erodibility factor K of tilled Alfisol derived from red sandstone and Cambisol on purple shale was the highest, and of eroded Entisol derived from Quaternary red clay was the lowest. The relationships between soil erodibility factors measured by rainfall simulator and natural rainfall were also established respectively. |
