在四川境内,大凉山东坡地区,通称为小凉山.山体高耸,坡面迎风,热量高,湿度大,土壤肥沃,森林资源丰富,为四川省林业基地之一.本区生长着由丝栗、石栎、木荷等高大乔木组成的常绿阔叶林和由麦吊杉(云杉)、云南铁杉、峨眉冷杉、槭、桦等组成的针阔混交林及由峨眉冷杉、苍山冷杉等组成的暗针叶林.这些树种除冷杉外,生长迅速,干直株高,材质坚硬、优良.土壤是森林的生活环境,森林在其生长发育过程中,又不断地改造土壤,只要掌握了存在于这二者之间的关系,就能促使土壤向不断提高森林生产率定向发展.
In the territory of Sichuan Province, the Dongpo area of Daliangshan is commonly known as Xiaoliangshan, with its towering mountaintop, windward slope, high heat, humidity, rich soil and rich forest resources, and is one of the forestry bases in Sichuan Province. , Quercus mongolica, Schima superba and other large trees composed of evergreen broad-leaved forest and the Conifer fir (Spruce), Yunnan hemlock, Emei fir, maple, birch and other components of the conifer and broad-leaved mixed forest and Cimicifuga fir, Cunninghamia fir Etc.
