| 摘 要： | 根据江西省鹰潭市红壤生态实验站自建气象站1997—2003年度观测资料和该站装填我国南方主要类型土壤的侵蚀小区土壤流失量实测数据,对降雨各因子与南方不同类型土壤侵蚀量的关系进行了分析。结果表明,在径流和雨强因子下,各土壤因子关系可用乘冥函数进行拟合;而在侵蚀性降雨量因子下,各土壤因子关系可用三次函数进行拟合。但由于土壤类型和同一土壤的原始利用方式不同,各土壤侵蚀量与不同降雨因子的回归方程式差异很大。

| Abstract: | Based on the observations of rainfall events and recorded soil erosion data on the plots-which was established particularly for typical soils of southern China,in the Ecological Experiment Station of Red Soil(EESRS),Yingtan City,Jiangxi Province,the relationship between sediment yield and rainfall factors was explored for the time period from 1997 to 2003.The results show that under the relationship between sediment yield and surface runoff could be described by a power function,while the relationship betwe... |
