Abstract:Through studying the spatial characteristics of slope soil erosion intensity and susceptibility in the small watershed of Shandong province, we find out the relationship between soil erosion intensity and soil susceptibility. In this study, we choice the small watersheds of Taian city and Qufu city to measure the slope soil erosion intensity and susceptibility of different slope and different parts of slope in different small watershed. The results show that the slope soil susceptibility variation is like wave, from the upper part to the lower part of the slope. And the law is the soil susceptibility of lower part of the slope is higher than the upper part of the slope. It show that the susceptibility of sediment area is higher than erosion area of the slope. At the same time, we can see the soil susceptibility of woodland is higher than grassland, and the susceptibility of grassland is higher than farmland in the middle part of the slope. From the slope different direction, we can see, the soil susceptibility of the slope exposed to the sun is the lowest. And the soil susceptibility and soil erosion intensity is negative correlation. The soil susceptibility of different part of the slope can reflect the soil erosion intensity of the slope.
