摘　　要：闽北山区地质、地貌复杂 ,降雨量多 ,经过 3次森林破坏 ,土壤侵蚀面积曾达 2 3 2 0km2 ,成为福建省土壤侵蚀的新的典型区域。区内暴雨多与降雨侵蚀力R值大、炼山全垦整地造林以及不合理的开发建设活动 ,是造成土壤侵蚀加剧的主要原因。介绍了新中国建立后区内土壤侵蚀演变的过程。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.
