摘　　要：对武功山草甸植被小群落下土壤活性有机碳性状和土壤养分性状的16个变量进行典型相关分析。结果表明：在0-20 cm,土壤有机碳性状与土壤养分性状的第一个典型相关系数达到极显著水平,其相关系数为0.994 9,在一定范围内,土壤有机质、铵态氮、磷、钾和硼含量与土壤有机质碳、微生物量碳和易氧化态碳含量呈显著正相关;在20-40 cm,土壤有机碳性状与土壤养分性状的第一个典型相关系数达到极显著水平,其相关系数为0.995 4,在一定范围内,土壤有机质、钾、钙、镁含量与土壤有机质碳、可溶性碳和易氧化态碳含量呈显著正相关,铜和硼含量与土壤有机质碳、可溶性碳和易氧化态碳含量呈显著负相关。On the behavior of soil active organic carbon and soil nutrient characters of 16 variables for canonical correlation analysis. Results show that in 0 - 20 cm, soil organic carbon and soil nutrient traits of the first canonical correlation coefficient reached extremely significant level, and the correlation coefficient is 0.994 9, within a certain range, the soil organic matter, ammonium nitrogen, ph osphorus, potassium and boron content and soil organic carbon, microbial biomass carbon and oxidation state carbon content was significantly positively related; In 20 - 40 cm, soil organic carbon and soil nutrient traits of the first canonical correlation coefficient reached extremely significant level, and the correlation coeffici ent is 0.995 4, within a certain range,, potassium, Calcium and magnesium content of soil organic matter and soil organic carbon, soluble carbon and oxidation state was significantly positively related to carbon content, copper and boron content and soil organic carbon, soluble carbon and carbon content of oxidation state has signifigant canonical correlation.
