Representation of sampling location.After collection of spatial data，such as land-use type and DEM，for runoff volume and sediment amount simulation，data used for model development were collected from four runoff plots with areas of4 m×10 m（Fig.3）.The representative of these four runoff plots lies in:（1）the soil type in the first，second and fourth runoff plots was red soil，and the average percentages of clay，silt and sand of red soil were 45.91%，45.09%and 9%，respectively.The soil type in the third runoff plot was calcareous soil，and the average percentages of clay，silt and sand of calcareous soil were 31.06%，44.94%and 24%，respectively.These four plots could represent the soil type of whole watershed well；（2）the average soil p H values of three points in the first and fourth runoff plots was 5.34 and 7.76，respectively，while the average pH values in the second and third runoff plots were both about6.84.The pH values of these four plots could cover the most pH values of the whole watershed（Table 1）.
