| 摘 要： | 为了解金毛狗群落与环境因子的相互关系,研究了重庆市金毛狗群落相对集中的北碚、涪陵、江津、永川、大足和铜梁等地区的环境因子、TWINSPAN分类、物种和多样性指数与环境因子的DCCA排序。结果表明:1)金毛狗群落生长在土壤为酸性、土壤含水量较高、郁闭度较高,并处于西北和东北坡向的水沟边。区域相近的金毛狗群落较相近,金毛狗的主要伴生物种为镰羽复叶耳蕨、狗脊、芒萁、山姜、大叶排草、荩草和里白;2)土壤含水量和海拔高度对金毛狗群落的影响较显著;3)金毛狗群落的物种多样性相似度较高,土壤有机质含量对物种多样性的影响较显著。 |

| Abstract: | 22 quadrats of Cibotium baromatz were selected to analyze quadrat environmental factors,TWINSPAN classification,companion species and DCCA order between diversity index and environmental factors for studying the relationship between Cibotium baromatz community and environmental factors. The results showed that Cibotium baromatz community normally usually grew in soil with acidity,high moisture and high closing degree along the sides of ditch toward northwest and northeast,the Cibotium baromatz community was... |
