摘要

This paper describes the series of research we've conducted to cope with the soil erosion. Red-soil sloping lands in south China frequently suffer soil loss as well as drought and flood disasters. This report gives a detailed description of the contents and methods of the research. In particular, we have adopted for the first time the soil infiltration devices for quantitative observation and measurement in test plots. From which, we reach preliminary conclusions that the plot covered with Bahia grass is of the lowest surface runoff and underground runoff, where the soil and water conservation effect is good; whereas the plot mulched with Bahia grass is of the second lowest surface runoff and the highest underground runoff, where its capacity for flood control and natural disaster reduction is good; however, the bared check plot is of the highest surface runoff and the lowest underground runoff, where its capacity for soil and water conservation is fairly poor and it is in more serious danger of suffering from drought and flood disasters.
