根据现有资料,将海南岛的主要土壤类型,划分为7个土纲、20个土类,即:铁铝土土纲的砖红壤、砖红壤性土、赤红壤和黄壤等土类;半淋溶土土纲的燥红土和红色石灰土等土类;初育土土纲的紫色土、黑色石灰土、火山灰土、新积土、滨海砂土、幼年土、石质土、粗骨土等土类;半水成土土纲的潮土和山地灌丛草甸土等土类;水成土纲的沼泽土和泥炭土等土类;盐碱土土纲的海滨盐土土类,以及人为土土纲的水稻土土类等。本文着重就其地理分布、剖面形态,以及其理化性质等方面,分别做概要的说明,比较全面地反映了海南岛主要土壤类型的基本概貌。
According to available data, the main types of soil in Hainan Island are divided into 7 soil types and 20 soil types, namely, the red soil of the iron-aluminum soil, the red soil of the brick, the red soil and yellow soil; Leaching clay soil of dry red soil and red lime soil and other soil; early soil soil purple soil, black lime soil, volcanic ash soil, new soil, coastal sand, juvenile soil, stone soil, coarse soil Soil such as semi-arid soil and soil mountain meadow soil mountain shrub meadow soil; soil water swamp soil and peat soil and other soil types; saline-alkali soil of the coastal saline soil, and human Soil and soil of the paddy soil class. This article focuses on its geographical distribution, profile morphology, as well as its physical and chemical properties and so on, respectively, to do a summary description, a more comprehensive reflection of the basic profile of the main soil types in Hainan Island.
