海南省儋州市砖红壤在中国土壤系统分类的归属研究

为了研究海南省儋州市典型土壤在中国土壤系统分类中的归属,以该市砖红壤地区4个具有典型代表性的土壤剖面为研究对象,进行成土条件调查,并分层取样进行理化性质测定分析。结果表明：调查的4个土壤剖面归属于铁铝土、富铁土和淋溶土3个土纲、湿润铁铝土、湿润富铁土和湿润淋溶土3个亚纲4个土类4个亚类,并分别对应到相应的4个土系;儋州市砖红壤在发生分类与系统分类体系中并不呈简单的对应关系,系统分类的划分指标要求更严格,分类更标准。...

In order to understand the attribution of typical soil of Danzhou in Chinese soil taxonomy,four typical profiles of laterite soil were researched in this study.The investigation into the soil environment was conducted and the stratified samples were analyzed in the aspect of physical and chemical properties.The four types of Danzhou lateritic soil profiles were classified into four soil series,under four Subgroups,four Groups,three Suborders as Moist Ferralsols,Moist Ferrisol and Moist Alfisol and 3 Orders as ferralsol,ferrisol and alfisol.The results showed that the relationship between soil genetic classification and soil taxonomy was not simply corresponding,which indicated that the criteria for sorting in the soil taxonomy was stricter and more standard.
