摘　　要：本文根据我国第二次土壤普查资料,依据《中国土壤系统分类检索》(第三版)中变性土诊断标准,对我国砂姜黑土主要分布区(安徽、河南、江苏和山东)的砂姜黑土所有土种进行了系统分类归属判别。结果表明:总共的54个土种中(安徽、河南、江苏和山东各13、20、6和15个),34个可以划归为变性土(安徽、河南、江苏和山东各7、16、5和6个),合计面积228万hm2(安徽、河南、江苏和山东各131万、59万、24万和14万hm2);26个砂姜黑土土种可划归为砂姜钙积潮湿变性亚类,8个为钙积潮湿变性土,其余属于雏形土或盐成土。对砂姜黑土的系统分类应该主要依据其黑土层的特性,而砂姜的存在与否只是决定亚类的特征。Based on the information from the 2sd national soil survey and the diagnostic criteria of Vertosols in Chinese Soil Taxonomy, this paper discusses the taxonomic classification of the soil-species of Shajiang black soils in its main distribution regions in China, i.e., Anhui, Henan, Jiangsu and Shandong provinces. The preliminary results showed that among the total 54 soil-species of Shajiang black soils, 34 soil species, with an area of 228×10^4 hm2, could bc classified as Vertosols, among of which, 26 as Shajiang Calci-Aquic Vertosols and 8 as Typical Calci-Aquic Vertosols respectively, the other soil-species of Shajiang black soils could be categorized as Shajiang-Aquic Cambosois or Aqui-Alkalic Halosols. The diagnosis of these kinds of soils should focus more on the black clay layer rather than the carbonate concrete layer which determines only the lower categories.
