红壤坡地水土流失规律研究
摘要
通过在第四纪红壤坡地建立标准径流小区进行试验
模拟了径流量与降雨量的线性相关方程
建立了降雨量、降雨强度与土壤侵蚀量的幂函数相关方程
得出了不同治理措施引起土壤侵蚀的临界降雨值
找出了第四纪红壤坡地水土流失的一般规律.
Abstract
The district of standard runoff were built in the slope land of the Fourth Century Red Soil in order that they could be used in experiments. Through analysis and studying
we simulated the linearity equation between runoff and rainfall
built the power function equation among runoff
the intensity of rainfall and the amount of soil and water erosion. It was got a critical runfall of causing soil and water erosion
and we discovered the common orderliness of soil and water loss at slope land of the Fourth Century Red Soil.
