土壤分类是土壤普查各项业务中最基本最重要的一项,并且贯穿于土壤普查的全过程.无论在野外调查阶段或是成果汇总阶段,土壤分类始终是个核心问题,对土壤普查的速度和质量有着十分重要的影响.前个时期,一些人曾对土壤普查中土壤工作分类的制订在方法上提出过“应细勿粗”和“宁错毋乱”的主张.基层各级土壤工作分类和野外调查做得细一些,以便能够收集和研究尽可能多的土壤信息,乃是保证和提高土壤普查质量的重要基础.因此,“应细勿粗”的提法是对的,有积极作用.但是“宁错毋乱”的提法很盲目,实不足取.本文拟举实例以剖析土壤工作分类中常见的错、乱现象以及错与乱的相互 Soil classification is the most basic and important one of all the soil census operations and runs through the whole process of soil census. Soil classification has always been a central issue both in the field investigation stage and in the summary stage. Quality has a very important impact.At the previous period, some people have made on the method of soil classification in the soil census proposed “should not be careful” and “rather wrong and not chaos.” The grass-roots level soil work classification As far as field surveys are concerned, it is important to be able to collect and study as much soil information as possible to ensure and improve the quality of soil censuses. However, the formulation of “rather than unnecessary chaos” is very blind and inadequate.In this paper, we give examples to analyze the common mistakes and chaos in the classification of soil and the mutual interlocution and chaos
