补充资料：黄壤
| 黄壤 yellow earth 发育于亚热带湿润山地或高原常绿阔叶林下的土壤。酸性，土层经常保持湿润，心土层含有大量针铁矿而呈黄色，故名。集中分布于南北纬度23.5°～30°之间。中国主要分布于四川、贵州等省，为南方山区的主要土壤类型。在山地的垂直带谱中，黄壤下部一般是红壤，上部以黄棕壤为多。黄壤的形成包含富铝化作用和氧化铁的水化作用两个过程。由于高温多雨、岩石风化强烈，在成土过程中难移动的铁、铝在土壤中相对增多；土壤终年处于相对湿度大的环境中，土体中大量氧化铁发生水化作用而形成针铁矿。黄壤分为3个亚类：①黄壤。多见于原生植被保存较少，次生栎类灌丛和稀疏马尾松、杉木混交林较多的山地，有机质含量随自然植被的不同而有很大差异。②灰化黄壤。多见于海拔较高、森林保存较好、郁闭度较大的地段，有明显的枯枝落叶层，表土呈强酸性，有机质含量达10％以上。③表潜黄壤。多见于亚热带山地的山脊地带，常年云雾弥漫，相对湿度较大，有较厚的枯枝落叶层，表层水分常呈饱和状态而有滞水现象，表层有机质含量达20％左右。黄壤的利用以多种经营为宜。已耕种的黄壤为防止土壤侵蚀，宜进行农田基本建设，多施有机肥和种植绿肥，并适量施用石灰和磷肥。
