| 摘 要： | 在对江西南昌市梅岭景区6个典型景点中的蜘蛛多样性进行调查、鉴定并获得其蜘蛛资源详实分布名录的基础上,结合另文对其多样性的比较研究结果,通过将其39个未确定种的各科属级物种丰富度、景点物种多样性、群落结构多样性和捕食功能多样性共13个指数作为变量对其区域特色种作用因子进行主成分、相关性和聚类等统计分析,揭示其多样性形成原因和方式。结果表明:景点物种均匀度、景点物种丰富度、景点物种优势度、捕食功能均匀度、群落结构丰富度、捕食功能丰富度是区域特色种形成的6个主要作用因子,各因子间普遍相关,且生态和遗传因素各有侧重地作用于区域特色种的形成。

| Abstract: | In this paper,the diversity of spiders in 6 typical scenic spots in the Meiling Scenic area of Nanchang City,Jiangxi Province was investigated,and the detailed distribution list of spider resources was identified and obtained.Combined with the results of comparative study on its spider diversity that had been reported on the other magazine,the formation cause and mode of the 39 undetermined species on list were revealed as a regional characteristic species by using a total of 13 indexes of their species richness,species diversity,community structure diversity and predation functional diversity as variables to analyze the main components,correlation and clustering of action factors.The results showed that the species evenness,the scenic spot species richness,the scenic spot species dominance,the predation functional evenness,the community structure richness and the predation function richness were the six main factors for the formation of regional characteristic species,and the various factors were common correlation,then the ecological and genetic factors each focused on their formation. |
