土壤工作分类是土壤普查外业开展之前,为适应野外调查制图工作中统一分类的需要,事先制定并带有预见性的初步分类系统.但它并不等于整个普查完成后所确定的制图单元和分类系统.制定一个切实可行的工作分类,是保证野外调查制图单元统一标准,避免混乱,提高工效的重要环节.我们在通县全面开展野外工作之前,在熟悉前人有关资料的基础上,通过五个典型公社的试点和部分路线勘查,初步拟定了本县的土壤工作分类方案,提供各外业组统一使用,保证了整个外业工作的顺利开展.全县完成外业工作后,只用了2～3天时间就完成了比土和拼图任务.
Soil classification is a preliminary classification system that is foreseen and foreseen in order to meet the requirement of unified classification in the field investigation and mapping before the soil census is carried out.However, it does not equal to the mapping unit determined after the completion of the census Classification system.Development of a practical classification of work is to ensure that the field survey mapping unit unified standards to avoid confusion and improve efficiency of an important part of our work in Tong County before the full field work on the basis of familiar with previous data on the basis of Five typical communes of the pilot and part of the route survey, the preliminary formulation of the county’s soil classification program to provide unified use of foreign industry groups to ensure the smooth operation of the entire field of work. County completed the field of work, only 2 to 3 days to complete the task than the soil and puzzle.
