摘要:
 以吉林金沟岭林场天然云冷杉林为研究对象，运用主成分分析、模糊线性隶属度函数法，分析不同土壤养分（pH值、有机质、全N、全P、全K、碱解N、有效P、速效K及土壤综合指标值）含量的差异及变动与林分针阔比的关系及其对林下灌木生物量的影响。结果表明，当林分的针阔比为7∶3时，林地土壤pH值、有机质、全N、全P、全K、碱解N、有效P、速效K均较高，且此时土壤综合指标值最高，土壤养分最好，林下灌木生物量也处于较好的状态。
Abstract:
 Taking the natural spruce fir forest in Jingouling Forest Farm of Jilin as the research object,using principal component analysis and fuzzy linear membership function method,the dynamics of different soil nutrients (pH,organic matter,total N,total P,total K,alkali solution N,available P,available K,and soil comprehensive index value) and their influences on understory shrub biomass were analyzed.The results demonstrated that when the ratio of coniferous to broad-leaved trees was 7∶3,the soil pH,organic matter,total N,total K,N and available K were all in high levels,the soil comprehensive index was the highest,and the biomass of understory shrub was in its optimal state.
