土壤侵蚀时空变异及其与环境因子的时空关系

土壤侵蚀的时空变异是指在一定的景观内 ,不同时间、不同地点的土地侵蚀特征存在明显的差异性和多样性。土壤侵蚀的时空变异是多重尺度上的植被、土地利用、气象 (降雨 )、地形和土壤等多因子综合作用的结果 ,但是就某一具体地区而言存在重点尺度和主控因子 ,土壤侵蚀的重点尺度与主控因子的时空关系因时间、空间和尺度而异。综述了土壤侵蚀的时空变异及其与环境因子时空关系的研究进展

Spatiotemporal Variation in Soil Erosion and Its Relation to Environmental Factors

The spatiotemporal variation in soil erosion means the soil erosion properties show the significant differentiation and diversity at different scales of time and space. Actually, the spatiotemporal variation in soil erosion is related to the joint influences of several environmental factors at multiple scales including vegetation, land use, meteorological factors (e.g. rainfall), topography and soil. However, the key scale and dominant factors are different for the different time, space and scale. This paper reviewed the studies on the spatiotemporal variation in soil erosion and its relation to the environmental factors. The specific attention was given to the studies on the Loess Plateau, China.
