摘要
研究了王朗自然保护区亚高山主要森林类型的土壤养分特征。结果表明,除全钾含量随土层深度增加而增加外,3个主要森林类型土壤全量养分、速效养分和有机质含量均随土层深度增加而降低。白桦林土壤氮的可利用性高于云、冷杉林。森林地表凋落物是主要的土壤有机碳库。总体来看,3个森林类型土壤养分含量较高,可很好的维持森林系统内的养分循环。
The features of soil nutrients of main forest types in subalpine of Wanglang nature reserve were studied.The results indicated that except that the total potassium content was increased along with increase of soil depth,the contents of total nutrient,available nutrient and organic matters in soil of the 3 main forest types were decreased along with increase of soil depth.The availability of soil nitrogen in birch forest was higher than that in spruce and fir forest.The ground litter in forest was main organ...
