本文对过去北京地区称为“褐土”的一类土壤的发生与分类问题进行了剖析。根据大量实际研究资料认为北京地区的生物气候条件并未对成土母质的性质有着深刻的影响,而土壤的地带性特点主要表现在土壤的水热状况以及有机质积累水平上,母质因素对土壤的其它性质的影响比较突出。因此提出北京地区土壤系统分类的新设计:以土壤本身的水热状况为土纲一级的分类标准,以土体中有无石性反应作为亚纲划分的标准之一。土类则以定量化的诊断土层作为分异特性。
This paper analyzes the occurrence and classification of a type of soil known as “cinnamon” in the past in Beijing. According to a large number of actual research data, it is considered that the bioclimatic conditions in Beijing do not have a profound impact on the nature of soil parent materials. The zonal characteristics of soil are mainly reflected in the hydrothermal conditions of soil and the accumulation of organic matter. Other properties of the more prominent. Therefore, a new design of soil system classification in Beijing is proposed: one is the classification standard of soil-level one based on the hydrothermal status of soil itself and the non-stone reaction in soil as a subclass. Soil is based on quantitative diagnosis of soil as a differentiating feature.
