摘 要:对小五台山自然保护区11种森林群落类型3个物种多样性指数和6个土壤养分指标等进行了典型相关分析。结果表明:物种多样性中的丰富度指数和多样性指数与土壤养分存在显著相关关系,并且都表现为与全N质量分数呈正相关,与pH值呈负相关。由此说明此地区土壤pH值和全N是森林群落植被多样性的限制性因子。Canonical correlation was used to study the relationship between three species diversity indices and six soil nutrient factors for eleven forest communities in Xiaowutai area. Results indicated that richness index and diversity index had significant correlations with soil nutrients. There were positive correlations between richness index, diversity index and soil total nitrogen, and negative correlations between richness index, diversity index and soil pH. It is shown that soil pH and soil total nitrogen are limiting factors on vegetation diversity of forest communities in Xiaowutai area.
