四川省地域辽阔,地貌形态多样,水热变异复杂,森林树种繁多,土壤资源丰富。土壤是林业生产的基础,不同类型的土壤,其生产能力各不相同,而且所能适应的森林树种亦有差别。按照土壤分类多以成土条件,成土过程,土壤属性和土壤生产力为依据的原则,四川的主要森林土壤类型可划分为:山地黄壤。山地红壤,山地褐土、山地黄棕壤、山地棕壤、山地暗棕色灰化土(山地棕色暗针叶林土)和紫色土等8个土类。
Sichuan Province has vast terrain, diverse topography, complex water and heat variations, abundant forest species and rich soil resources. Soil is the basis of forestry production, different types of soil, their production capacity varies, but also can adapt to the forest tree species are also different. According to the principle that soil classification is mostly based on soil formation conditions, soil formation process, soil properties and soil productivity, the main forest soil types in Sichuan can be divided into: mountainous yellow soil. Mountainous red soil, mountainous cinnamon soil, yellow mountain brown soil, mountain brown soil, mountain dark brown ash soil (dark brown coniferous forest soil) and purple soil 8 soil.
