As an ecological process, soil erosion which endangers human existence and development has been one of environmental problem around the world for a long time. Affected by various environmental factors, soil erosion risk has obvious spatial distributions. Taked the Zhu River small watershed of red eroded area of South China as an example, selected the five risk factors of rainfall erosion, terrain...
Soil erosion which endangers the human survival and development has been an important environmental problem around the world for a long time. The complexity and diversity presents in Zhuxi Small Watershed which is one of the thirty typical monitoring watersheds in China. The information which include rainfall, slope, soil, vegetation and land use, was obtained by combining 3S techniques with field...
Spatial pattern heterogeneity exhibits various patterns at different scales; therefore different observed scales affect the results of spatial analysis. Effects of changing scale on spatial analysis have been studied for decades in geography and ecology, but few previous studies expounded the quantitative approach about the optimum grain. Some studies describe the eroded landscape pattern neglecting...
