英文摘要： For the matter that the problem of the karst soil erosion mechanism to research especially in weak link currently, in the domain of studying soil erosion of Karst tooth sloping fields, This program will study it in new different visual angle,with the integrative applying the technique and method for observation and experiment of soil erosion, at typical karst sample area selected for bare karst teeth sloping field distribution on Yunnan Plateau, comprehensive usage the physics and chemistry and engineering test analytical, modern tiny geography diagraph system technique, karst soil erosion related theory of many academicses and synthesize technique methods and like contrast, research with observation-analysis for the function system and water erosion process, main water power characteristic and water erosion luck surrounding its soil erosion moves way, function mechanism problems, such as and function mechanism. the study result will make some necessary basic for this subject be researched in-depth at aftertime, and offer reference data to control soil erosion of plateau karst environment.
