红土地,顾名思义,乃是指那些色泽泛红色或偏红棕色、紫红色的土地或土壤而言。它是土地资源的一种类型。它们含有丰富的矿物质,尤是含有大量的铁锰元素,经氧化作用而变成暗红色或赤红色的铁锰氧化物,因而形成了所谓的“红土地”。 Red earth, as the name implies, refers to those reddish or reddish brown, purplish red earth or soil. It is a type of land resource. They are rich in minerals, especially iron-manganese oxides, which contain a large amount of iron-manganese and oxidize to dark red or reddish colors, forming the so-called “red earth.”
