为了制止土壤风蚀的发展,消除风蚀危害,改造风蚀土壤,有根据地建议正确的土地利用和管理措施,在土壤普查中应有一套关于风蚀土壤的分类和制图方法。去年在内蒙古鄂尔多斯地区进行了考察,编制几个公社的土地荒漠化图时,曾涉及到风蚀土壤的分类和制图问题,现提出一些意见供实际工作中的参考。 一 风蚀土壤的分类问题,国内外有过不少研究。根据前人的工作和我们长期在风沙区地的研究,我们认为,风蚀土壤的分类应该回答下列要求:(1)能预测土壤风蚀的倾向或易蚀性,即预测在不同的土地利用方式下,风蚀发展的可能性和速度;(2)反映风蚀过程的特点和实际的风蚀程度;(3)实践上应用比较方便。
In order to stop the development of soil wind erosion, eliminate the risk of wind erosion and rebuild wind-eroded soil, it is suggested that proper measures of land utilization and management should be proposed. There should be a set of classification and mapping methods for wind-eroded soil in the soil census. In the past year, we conducted an investigation in the Ordos area of Inner Mongolia. When compiling plans for land desertification in several communes, we have been involved in the classification and mapping of wind erosion soils. We have put forward some suggestions for reference in practical work. A wind erosion soil classification, there have been many studies at home and abroad. Based on our predecessors’ work and our long-term research in the windy and sandy areas, we believe that the classification of wind-eroded soils should answer the following requirements: (1) Prediction of soil wind-erosion propensity or erosivity, that is to say, under different land-use patterns , The possibility and speed of wind erosion development; (2) reflect the characteristics of wind erosion process and the actual degree of wind erosion; (3) more practical application.
