紫茎泽兰入侵对高黎贡山百花岭人工林植物群落多样性的影响

Effects of Ageratina adenophora invasion on the structure and diversity of plantation plant community in Baihualing area of Gaoligong Mountains.

  • 摘要: 为掌握紫茎泽兰入侵对高黎贡山百花岭地区植物多样性的影响,采用样方法调查了高黎贡山保山段百花岭周边3个受紫茎泽兰入侵人工林样地中的草本和灌木植物种类和数量,分析了物种组成、群落结构、群落物种丰富度指数、多样性指数和均匀度指数。结果表明:3个样地共采得植物93种,隶属26目38科83属;紫茎泽兰入侵造成样地植物群落物种数和出现频度下降明显,入侵地的物种丰富度指数、Simpson多样性指数、Shannon−Wiener多样性指数、Pielou均匀度指数下降极显著;随着月份增加,入侵地的Simpson多样性指数和Shannon−Wiener多样性指数均无显著变化,物种丰富度指数和Pielou均匀度指数于10月上升显著;入侵地群落结构变化明显,荨麻、青蒿、荩草、马唐草表现出较好的物种多度和竞争作用。研究得到了紫茎泽兰入侵状况下高黎贡山白花岭人工林草灌植物名录,可为高黎贡山生物生态安全评估提供植物多样性数据基础,为基于生物多样性的紫茎泽兰生态防控策略制定提供参考依据。

     

    Abstract: In order to understand the impact of Ageratina adenophora invasion on plant diversity in the Gaoligong Mountain area, a sampling method was used to investigate the species and quantity of herbaceous and shrub plants in three plantaion plots around Baihualing in the Baoshan section of Gaoligong Mountain, which were invaded by A. adenophora. The species composition, community structure, as well as the species richness index, diversity index, and evenness index of the community were analyzed. The results showed that a total of 93 plant species were collected from the three plots, belonging to 26 orders, 38 families, and 83 genera. The invasion of A. adenophora caused a significant decline in the number, frequency, abundance and other characteristics of plant community species in the sample plot, and the species richness index, Simpson diversity index, Shannon Wiener diversity index, Pielou evenness index of the invasion plot decreased significantly. With the increase of months, the Simpson diversity index and Shannon Wiener diversity index of invasive areas showed no significant changes, while their species richness index and Pielou evenness index increased significantly in October. The community structure of the invaded area has significant changes, with Urtica fissa, Artemisia caruifolia, Arthraxon hispidus, and Digitaria sanguinalis exhibiting better species abundance and competition. These results enrich the list of grass and shrub plants under planted forest in Gaoligong Mountain, provide plant diversity data support for the ecological safety assessment of Gaoligong Mountain, and provide reference basis for the next step of prevention and control of A. adenophora.
