长期以来我们对黄壤的发生、特性和分布总觉得模糊不清。在土壤调查制图时;因红壤黄壤在形态性质上不易区分,所以在确定南方山地红壤带和黄壤带的垂直分布界线时,只有按海拔高度来划分。1982年10月在重庆召开的第三次全国森林土壤学术讨论会上有两篇都是有关广东鼎湖山的土壤论文,其中一篇把红壤黄壤界线划在300米,而另一篇划在700米,说明划分标准还不统一。云贵高原是我国黄壤集中分布区,根据已有的资料看来,那里的黄壤是否典型、黄壤是否为湿润气候的产物,都值得讨论。本文就多年来的考察,结合有关论著,谈一点不成熟的看法,希望能起到抛砖引玉的作用。
For a long time, we have always felt vague about the occurrence, characteristics and distribution of yellow soil. At the time of soil mapping survey, because the red soil yellow soil is not easy to be distinguished in morphological properties, the vertical distribution boundary of the red soil zone and the yellow soil zone in southern mountainous area can only be divided according to the altitude. Two of the three soil papers on Dinghushan, Guangdong, October 1982, held in Chongqing at the Third National Symposium on Soil and Soil, one of which delimited the yellow line of the yellow soil at 300m and the other at 700 M, indicating that the standard is not uniform. Yunnan-Guizhou Plateau is the distribution of yellow soil in our country. According to the available data, it is worth discussing whether the yellow soil is typical and whether yellow soil is the product of humid climate. This article on the study over the years, combined with the relevant treatises, talk a little immature view, hoping to play a valuable role.
