<正>江苏省至江西省东北部各低山区森林土壤33个代表剖面的数据表明,土壤类型及其分布并不完全符合经典地带性规律。按气候与地貌分层作出的排序图显示,在这个湿润暖温带到亚热带的过渡地区内,土壤分布至少同时存在两种水平地带谱,一种表现在山麓或阶地古风化壳上,另—种则涉及坡地近代侵蚀面上的土壤。这两种水平地带谱在平面上实际上形成一种双重(或甚至多重)水平地带性交叠的格局。

In low mountain areas of Jiangsu and the northeastern part of Jiangxi provinces, data from 33 representative profiles showed that soil great groups or subgroups and their distribution did not fully coincide with the classical theory of soil zonality.And it can be seen in ordination figure, in which data sets were stratified according to climatic and geomorphic fators separately, that there are at least two horizontal zonal spectra of soils coexisting within the transitional region from humid warm temperate zone to subtropics: one presents itself on ancient weathering crusts of foothill or terrace, another concerns the soils on modern erosion surface of slope only. These two spectra partly overlap each other and may be likened to the fallen dominos, and thus a partly overlapping pattern of dual (or even multiple) horizontal zonalities emerges.
