棕壤是广泛分布于世界温暖湿润气候区的一种重要森林土类。然而迄今为止,国际土壤学界对棕壤的发生、分类及其与相邻土类的关系等认识尚有一定分歧。为此,根据现有资料,对不同地区的棕壤加以比较,对于进一步认识对棕壤的发生学特点及其分类是有益的。本文仅对欧亚大陆东、西部(以下简称东、西部)的棕壤作一初步比较。共收集约105个棕壤剖面的理化分析数据,从中选择出能较好反映当地生物气候条件的69个剖面(其中,我国冀北山地的三个剖面是笔者采集和化验分析的),就成土条件和主要发生学指标按地区进行比较。
Brown earth is an important forest soil widely distributed in the warm and humid climates of the world. However, so far, there is still some discrepancy between the international soil science community on the occurrence and classification of brown earth and its relationship with the adjacent soil. Therefore, according to the existing data, comparing brown soil in different regions is beneficial for further understanding of the characteristics and classification of brown soil. This article only makes a preliminary comparison of the brown earth in the east and west of Eurasia (hereinafter referred to as the east and west). We collected a total of about 105 profiles of brown soil profiles of physical and chemical analysis of data, select from to better reflect the local bioclimatic conditions of the 69 profiles (of which, Hebei Province, Hebei Province, the three sections of the author is collected and laboratory analysis) Soil conditions and major occurrences are compared by region.
