摘要

Ten runoff plots with different planting patterns were established for experimental observation in Yangjichong small watershed of Longli County in Karst region of Guizhou Province. Results show that under the same rainfall condition, shrub land, natural grassland and abandoned land presented the best function of soil and water conservation. The function of soil and water conservation was poor for arbor planting pattern, because the shrub layer, herb layer and forest floor were not formed. Because of no-tillage, surface crust and other effects, the function of soil and water conservation in slope farmland was better than that in runoff plots with arbor planting pattern. Guizhou not only is one of the provinces with the most serious soil and water loss in China, but also is the unique province without the support of plains. The karst topography development is completed, proportion of slope land is high, soil erosion is severe, lots of base rocks exposes, and land productivity reduces greatly, which forms rocky desertification in Guizhou province. Hydraulic erosion on slope is the important soil erosion type of karst region in Guizhou. Therefore, the study on runoff and sediment yield of karst region in Guizhou has great significance. A series of research achievements about basin rainfall runoff and sediment yield at home and abroad had been reported. Research showed that between the land use status，especially the vegetation actuality and sediment yield had correlation. The sediment transport in different conditions with different vegetation is different. Some scholars consider that there was power function relationship between silt content and flow through experiment, but there were some scholars with dissenting opinions, and they believed that there was no significant relationship between silt content and flow. Lots of experimental researches about runoff sediment yield had been carried out in China and lots of research achievements had been got. But there were few researches about runoff sediment yield on the slope in karst region. This paper took Yangjichong small watershed of Longli county in karst region of Guizhou as an example to research runoff sediment yield law of typical small watershed under different platting patterns on the slope, and to study soil and water conservation functions of different vegetation measures, for providing reference for water and soil loss control and land rectification on slope in karst region of Guizhou.
