广东潮州市石庵山灌木与草丛蜘蛛种类及多样性分析

Analysis on the spiders species and diversity inshrubs and grassland in Shi＇an Mountain, Chaozhou city, Guangdong Province, China

2013年5-8月份，我们对广东莲花山余脉石庵山的灌木与草丛蜘蛛种类和群落结构进行了调查，采用样方和震落承接的方法，共采集蜘蛛标本1536头，经鉴定隶属于15科29属37种。优势类群为跳蛛科、管巢蛛科、蟹蛛科和园蛛科，占总个体数的74．70％。Margalef丰富度指数（5R）、Pielou均匀度（J）指数表明，潮州石庵山灌木与草丛蜘蛛种类和数量丰富，分布均匀，Shannon多样性指数（H’）较高，蜘蛛群落结构稳定。

The community structure and species of spider in shrubs and grassland in Shi＇an Mountain, Chaozhou City, Guangdong Province, China, were studied from May to August, 2013. With sample and shaking-out together, we collected spider 1608 individuals, which belonging to 15 families, 29 genera and 37 species. The species in Salticidae, Clubionidae, Thomisidae and Araneidae belong to dominant species, about 74.70% of the total number of individuals. The result of analysis, by using Margalef richness index （SR） and Pielou evenness index （J）, shows that spider species and individuals in shrubs and bushes of Shi＇an Mountain is abundant, and homogeneous distribution, shrubs and bushes have high Shannon diversity index （H＇） , and with jarless community structure.
