| Abstract: | The geology and landforms of the mountainous area located in the northern Fujian are complicated with more precipitation. After three times deforestation, the area of soil erosion has increased to 2 320 km 2, becoming a new typical region of soil erosion in Fujian Province. In the region, more rainstorms, great R value of rainfall erosive agent, burning the grass on waste hills and conducting whole reclamation for soil preparation and afforestation and irrational activities of development and construction are the main reasons for intensifying soil erosion. The paper introduces the process of soil erosion evolution of the region after founding of new China. |
