| 摘 要： | 根据野外样地调查数据,应用方差均值比率法、聚集强度指数法和相关分析法,对鄱阳湖洲滩优势植物种群分布格局进行了研究,分析了其形成的原因,并比较了各指数间的关系.结果表明,鄱阳湖洲滩优势植物种群都为聚集分布,它们的聚集强度存在差异,聚集度最高的是糙叶苔草(Carex scabrifolia),最小的是稻搓菜(Lapsana... |

| Abstract: | Based on the data from the fields,the patterns of dominant populations of plants in islets of Poyang Lake were investigated by using dispersal index ratio method,canonical correspondence analysis method and clump intensity indexes(the intensity index k of negative binomial distribution,clump intensity,Cassie index,patchiness index and mean crowding).The cause involved with the pattern was analyzed and the relationship between these indexes was surveyed by their correlation coefficients.The results showed th... |
