| 摘 要： | 近年来,由于全球气候变暖,加上草地长期超载过牧及经营管理不善等人为因素的影响,致使害草轮叶马先蒿(Pedicularis verticillata L.)在巴音布鲁克高寒草原大面积发生,为防止轮叶马先蒿蔓延,合理利用草地资源,有效控制和防止害草的蔓延。本文开展不同土壤因子对轮叶马先蒿群落结构影响研究,结果表明轮叶马先蒿盖度与地上生物量及其群落物种丰富度、物种多样性和均匀度与土壤含水量关系密切,而与其它土壤因子无相关性,说明在巴音布鲁克高寒草原土壤含水量的高低是限制轮叶马先蒿的主要生境因子,应通过控制水源处的传播来防止其大面积蔓延与扩散。

| Abstract: | In recent years,the P.verticilata occurred seriously in Bayanbulak alpine grassland because of global warming,grassland long-term overloaded,poor management man-made factors and so on.In order to prevent P.verticilata's speeding and reasonable use the grassland resources,this paper carried out the effect of different soil environmental factors to P.verticilata It turned out that P.verticilata's coverage,aboveground biomass,species diversity,the richness index,diversity index and evenness index of plant comm... |
