为了掌握常吉高速公路边坡多花木兰人工生态恢复植物群落的种间竞争和生态位等生长状况,运用Hegyi的单木竞争指数模型、Shannon-Wiener公式和Shoener公式对多花木兰人工植物群落的种内与种间竞争强度、生态位宽度与生态位重叠进行研究。结果表明:多花木兰种内竞争能力与个体的地径径级成正比,多花木兰竞争能力大于刺槐、小叶女贞,原有配置的马尾松等植物已经死亡;群落各种群生态位宽度的大小顺序为:多花木兰>刺槐>小叶女贞,分别为2.271、2.147、2.088;群落各种群的生态位重叠值较大,多花木兰和刺槐的生态位重叠值最大,为0.793,多花木兰和小叶女贞生态位重叠值最小,为0.632。多花木兰能够很好地适...

In order to understand the growth status of Magnolia multiflora manmade plants community for ecological restoration at the slope engineering of the expressway from Changde to Jishou,based on the analysis of Hegyi single tree competition index model,Shannon-Wiener and Shoener formula,the population competition intensity and niche breadth and niche overlap of Magnolia multiflora manmade plants community were calculated.The results indicated that：the competitiveness of Magnolia multiflora had a positive correlation to DBH,and its competitive was ...
