摘要
经对完达山森林土壤肥力状况的分析表明:土壤有机质含量因土壤种类不同而异,最高的是棕色针叶林土,可达30%以上,全氮、全磷、全钾含量与有机质基本相同。在典型暗棕壤中,林分类型不同,土壤养分含量差异显著。土壤养分随坡度增大而减少,有机质和全氮含量随坡位下降而下降。
Analysing situation of forest soil in Wanda Mountain showed that organic matter content of soil was different in different types of soil,the highest was in brown confer forest soil,above 30%;In dark brown forest soil,in different types of stand,soil fertility is more as the gradient is less.Organic matter and tolal N of soil were less with the gradient reducing.
