摘要
莽山亚热带山地土壤垂直带谱发育良好,红壤、山地黄壤、暗黄棕壤、山地灌丛草甸土的分布和土壤特性,成土过程受当地的地形、气候、母质、植被等成土因素的影响,亚热带山地还分布有较大面积的粗骨土、石质土及少量沼泽土,其土壤特性和地带性土壤有较大差别,在利用上应予以充分的注意,山地灌丛草甸土粘粒中含有大量的三水铝石,可能是由斜长石直接风化而来的。
The spectrum of soil vertical distribution in subtropical mountains inMangshan mountainous area is well developed. The distribution of red soil, mountain yelowsoil, mountain dark yellow-brown soil and mountain shrubby-meadow soil, the soil charac-teristics and the processes of soil formation are strongly affected by the local soil formationconditions, such as topography, parent material, climate and vagetation. Relatively largearea of skeletal soil and lithosol, and scattered bog soil are also distributed in subtropicalmountainous area. Their characteristics are very different from zonal soils. So great atten-tion should be paid to their utilization. A large amount of gibbsite exists in the clays ofmountain shrubby-meadow soil, which probbably weathered from plagioclase directly.
