闽南地区不同土地利用类型土壤侵蚀现状分析

Present situation of soil erosion with different land utilizing types in south Fujian

据2000年遥感调查结果统计分析,闽南地区土壤侵蚀面积为 3 977.94km2,占土地总面积的15.61％。其中,旱地土壤的侵蚀最为严重;其次为草地,草地的侵蚀主要发生在覆盖度低的土地上;林地的侵蚀率虽然在各地类中最低,但林地侵蚀面积在各地类中最大。该区应重点加强坡耕地的改造与植被恢复工作。

The result of remote sensing survey in 2000 showed that the soil erosion area in south Fujian was 3977. 94 km2, which occupied 15. 61% of total land area; the soil erosion in dry farmland was the most serious; secondly for grassland, which soil erosion occured mainly in low coverage of upper soil; though the ratio of soil erosion in woodland was the lowest,the total area of soil erosion was the largest. The reformation of sloping arable land and the resumption of vegetation should be strengthened.
