鄂东大别山区是一个花冈片麻岩土壤侵蚀的严重地区,它分布于黄冈地区十个县,面积8200平方公里。山丘森林区的土壤年侵蚀模数为2.1—165吨/平方公里,水平梯地的多种经济林园区为43.4—3940吨/平方公里,土层裸露的荒山区为260—10400吨/平方公里,陡坡开荒种植区为2100—10800吨/平方公里,常耕平地一般为00吨/平方公里左右。如何防止土壤侵蚀,做到充分合理开发利用水土资源,发展山区生产,为社会主义建设服务,是人们应该很好地认识和迫切解决的问题。 造林整地和土壤的侵蚀关系十分密切,在一般的情况下,造林整地挖毁了地被物,破坏了土层的自然结构,产生了雨滴对
The Dabie Mountains in eastern Hubei Province is a serious area of soil erosion of the Ganga gneiss. It is located in 10 counties in the Huanggang area with an area of 8,200 square kilometers. The erosion modulus of the soil in the hill forest area is 2.1-165 tons per square kilometer, 43.4-3940 tons per square kilometer in various economic forest gardens in the level ladder, and 260-10400 tons / km2 in the uncultivated barren mountainous area , Steep slopes wasteland planting area of 2100-10800 tons / square kilometers, often tillage flat to 00 tons / square kilometers. How to prevent soil erosion, fully and reasonably develop and utilize soil and water resources, develop mountainous areas and serve the socialist construction are issues that people should well understand and urgently solve. Afforestation and soil erosion and soil erosion are closely related, under normal circumstances, afforestation and soil preparation to destroy the ground cover, destroyed the natural structure of soil, resulting in pairs of raindrops
