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。

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 % ;

盆谷地中山棕色针叶林土生态单元。盆谷地土壤生态系统的各个土壤生态单元分别具有各自的地方气候、地形条件、土壤类型和资源优势，因此它们有着不同的经营方向。

Each soil ecological unit of the basin-valley soil ecosystems has its own particular local climates , relief conditions , soil typ - es and resource advantages , therefore , it has a different develop - ing direction from the others ' .
