摘要
盐成系列的土壤，是新疆面积大，分布广泛的类型之一，其中一部分历来被视为垦殖对象和耕地后备土壤资源。对它进一步研究，区分类型，具有多方面的意义。故被列入由中国科学院南京土壤研究所主持开展的中国土壤系统分类研究之中。新疆盐成土性态独特复杂，类型多样，几乎同中国土壤系统分类（修订方案）中所列的类型都能相对应。如干旱正常盐成土和潮湿正常盐成立及分别下属的众多亚类。本文根据过去和新近工作的资料，着重总结了正常盐成土的发生特点、诊断层、诊断特性，旨在促应用，求提高。
Xinjiang is located in the middle latitudes where is typical arid land charac-erised by dry climate,which affect the formation,types and distribution of Halosols. Accord-ing to the Chinese Soil Taxonomic Classification (Revised proposal) by diagnostic horizonsand diagnostic characteristcs, Halosol order in Xinjiang is devided into 2 soil groups, i, e.Aridic orthic Halosols and Aquic orthic Halosols,and 10 soil subgroups, i,e. Dilluvid Aridicorthic Halosols,Gypsic -salipan Aridic orthic Halosols,Gypsic Aridic orthic Halosols,TypicAridic orthic Halosols,and Gelic Aquic orthic Halosols,Crustic Aquic orthic Halosols,Para-alkalic Aquic orthic Halosols,Gleyic Aquic orthic Halosols, Mollic Aquic orthic Halosols,typic Aquic orthic Halosols. A part of Halosols is reclamation and cultivation wasteIand inXinjiang- For the future,it will be object of expanse the areas under cultivation,which is ofgreat significance for utilization and study of soils.
