Abstract：Based on the observation and statistics of soil erosion and water loss in the sloping field,it is clear that the runoff depth and erosion would change along with the gradient,farming measures and vegetation.When the gradient increases or farming measure is changed from horizontal slope to the longitudinal one,the water loss and soil erosion would be incereased,and the different factor combinations of farming and vegetation make great impact on it too.The sequence of the factors about runoff has been got from the Gray Correlation Method: gradient > farming >vegetation is the weakest.The similar sequence about erosion is like this: farming>gradient >vegetation.Therefore,the interaction of them is of great value to analyze the change law of soil erosion and water loss,and it will be helpful to its prevention and management.
