- Abstract:
- Sloping fields are the base for studying a whole drainage basin. There are many factors that influence the slope soil erosion, but the most important is terrain. Cesium-137 and GIS (Geographical Information System) technology was used as main methods and several natural conflux slopes in gullied area of Loess Plateau were taken as studying objects, a preliminary study from a microcosmic point of view on the influences of different terrain factors was made. According to the vertical variation rules of slope erosion, the differences of soil erosion amount between different slope positions was studied and the contributions of different terrain factors was analyzed. The result shows:in micro scale, the influence of general factors such as gradient and slope length is not as distinctive as in proving ground;it seems that the role of these factors move to a backseat. By means of GIS, we can find some rules that are hard to be found by routine methods, it can help us to understand the erosion law more profoundly.
