黄土高原水土流失重点地区——宁夏固原地区,是全国最贫困的地区之一。该地区气候干旱,风沙、冰雹等自然灾害频繁,农村“三料”俱缺,特别是燃料奇缺,迫使农民铲草皮、挖草根、烧畜粪,加剧了水土流失和肥料短缺,造成农业生产中的恶性循环。因此,建设“三料”林基地,有效地解决烧柴问题,成为加快发展本区农牧业生产的重要环节。为了搞清全区现有人工灌木林资源、类型和生产潜力,并根据其自然和社会条件,明确发展方向,进行合理配置,综合发挥其生态效益和经济效益,我们在1980年调查的基础上,1985年再次进行了补充调查研究。
Loess Plateau area of ?? soil erosion - Ningxia Guyuan area, is one of the poorest areas. Natural disasters such as drought, sandstorms and hail in the climate are frequent in the region. The shortage of “three materials” in the rural areas, especially fuel shortage, forcing farmers to scoop the grass, dig grass roots and burn livestock manure, exacerbating soil erosion and fertilizer shortage and causing agricultural production In the vicious cycle. Therefore, building “three materials” forest bases and effectively solving the problem of burning firewood have become an important part of accelerating the development of agriculture and animal husbandry in this area. In order to find out the resources, types and production potential of the existing shrubbery in the whole region, and according to its natural and social conditions, it is necessary to set a clear direction for its development, allocate it rationally and give full play to its ecological and economic benefits. Based on the 1980 survey In 1985, a supplementary survey was conducted again.
