摘要
在GIS的支持下,研究了闽南地区地形坡度与土壤侵蚀之间的关系。结果表明,水力侵蚀是闽南地区的主要土壤侵蚀类型,其面积占总侵蚀面积的97.4％;水力侵蚀中有1/3的面积分布在≤5°的坡地上,而且>25°坡地的土壤侵蚀面积最小;大部分的风蚀和工程侵蚀分布在≤5°的坡地上。
The relationship between slope degree and soil erosion in south Pujian was studied by GIS. The results showed that water erosion was the main type of soil erosion, which accounted for 97. 4% in the total area of soil erosion. One-third of water eroded area distributed in the slope less than 5°, while the eroded area >25° was the smallest. Most of the areas in wind erosion and engineering erosion distributed in the slope area less than 5°.
