摘要
以可靠的黄土是冷干气候条件下发育的狭义古土壤的研究新成果为依据 ,结合野外调查和室内分析资料 ,探讨黄土高原的土壤资源特点和对农林业发展的作用。研究结果表明 ,西北黄土区是世界上土壤资源最富集的地区 ,黄土是结构最好 ,性质优越 ,化学元素非常丰富的宝贵土壤资源 ,具有生长品质优良农作物的性质和重要的开发利用价值。
In this paper, the characteristics of soil resources and their effects on the agricultural and forestry development in the Loess Plateau are researched based on the reliable achievements in loess research, a kind of the narrow-sense paleosol formed under the cold-dry climatic conditions and by combing the field investigation and laboratory analysis. The results show that the Loess Plateau in northwest China is the region with the most enriched soil resources in the world, loess is the valuable soil resources with fine structure, advantageous properties and rich chemical elements, and possesses the properties of growing high-quality crops and the important exploitation and utilization values
