Abstract
[Objective] The aim was to study the runoff yield characteristics of the slope surface runoff under different control measure conditions in Shiqiao small watershed of Karst area. [ Method ] In the test area with the comprehensive control for waster and soil loss in Shiqiao small watershed of Karst area, 23 runoff plots and 3 plots of fixed co mmunities were set up according to the different control measure conditions, through long - term positional observation, the basic data from 2005 and the monitoring data in 2006 ~ 2009 after conducting the comprehensive control of small watershed were selected and the runoff yield characteristics of the slope surface runoff under different control measure conditions were analyzed. [ Result] The effects of different slope degree on the runoff depth were in order of the runoff depth of 392 mm at 5° < that of 404 mm at 10° < that of 423 mm at 15° = that of 423 mm at 20° < that of 424 mm at 25° < that of 438 mm at 30° < that of 442 mm at 40°. The effects of different slope degree on the soil erosion modulus were in order of the soil erosion modulus of 38.08 t/km2 · a at 5 ° < that of 83.90 t/km2 · a at 10° < that of 120.50 t/km2 · a at 15° and that of 136.21 t/km2 · a at 20° < that of 210.50 t/km2 · a at 25° < that of 272.71 t/km2 · a at 30° < that of 308.08 t/km2 · a at 40°. [ Conclusion] The runoff depth and the soil erosion modulus were all enhanced with the increase of the slope degree, and the slope length was closely correlated with the runoff depth.关键词
