Based on the observation in runoff plots and gully cross-section in the field
the relationship between runoff and sediment yield for different soil and water conservation measures under different rainfall character conditions was studied.The effects of prophase rainfall and rainfall characters on runoff and sediment yield were analyzed.Soil and water conservation benefits of vegetation were discussed.Results showed that runoff and sediment from runoff plots with the application of prophase rainfall were greater under the conditions of the same rainfall and soil and water conservation measure.The larger the difference in the character of two rainfall events was
the larger the difference in the amount of runoff and sediment yield from runoff plots was.For the different measures
the benefit of level terrace was the highest; vegetation measure combined with appropriate engineering measure also obtained a good benefit of soil and water conservation.In the initial stage of vegetation enclosure
engineering measure must be used to improve the environment of ecological recovery.Gully head protection measure can well protect gully head and control gully erosion.
