土壤分布

大围山土壤分布自下而上依次为山地红壤、山地黄壤、山地黄棕壤和山地灌丛草甸土，在海拔1100m以上的山间盆地和凹地间有草甸、沼泽土分布。

Soil distribution from the foot to the top were : mountain red soil , mountain yellow soil , mountain yellow-brown soil and mountain meadow soil . Above the 1100 m of absolute altitude of the intermountain basin is bog soil .
