首发时间:2014-01-26
摘要:本次对江西相山铀矿蜘蛛资源及区系分布进行调查,共采到标本453份,经分类鉴定得知:它们隶属于28科75属143种,其中,有1个江西新记录科,1个江西新记录种和18个未确定种。蜘蛛群落结构多样性分析表明,Marglef丰富度指数M大小依次为:地下穴居型>地表穴居型>壁面结网型>叶面结网型>穴隙结网型>地面游猎型>叶面游猎型>枝间结网型;Berger-Parker优势度指数d大小依次为:壁面结网型>地下穴居型>地表穴居型=叶面结网型>穴隙结网型>枝间结网型>地面游猎型>叶面游猎型;Simpson多样性指数D大小依次为:壁面结网型>地下穴居型>叶面结网型>地表穴居型>穴隙结网型>地面游猎型>叶面游猎型>枝间结网型;Mackintosh均匀度指数E大小依次为:枝间结网型>叶面游猎型>穴隙结网型>地面游猎型>叶面结网型>地表穴居型>地下穴居型>壁面结网型。蜘蛛捕食功能多样性分析表明,Marglef丰富度指数M大小依次为:蚂蚁食性=鞘翅食性>广食性>膜翅食性>半翅食性>同翅食性>双翅食性>直翅食性>寡食性>鳞翅食性;Berger-Parker优势度指数d大小依次为:蚂蚁食性>鞘翅食性>同翅食性=半翅食性>广食性>膜翅食性>直翅食性>双翅食性>鳞翅食性>寡食性;Simpson多样性指数D大小依次为:蚂蚁食性>鞘翅食性>同翅食性>半翅食性>广食性>直翅食性>膜翅食性>双翅食性>寡食性>鳞翅食性;Mackintosh均匀度指数E大小依次为:蚂蚁食性=鞘翅食性>广食性>膜翅食性>半翅食性>同翅食性>双翅食性>直翅食性>寡食性>鳞翅食性。总之,江西相山铀矿蜘蛛类型以农林和人居区常见种类为主,具少数特色蜘蛛种类,生态行为和种系演化常有异样。

Studies on the spider community structure and predational diversity in Xiangshan uranium mine in Jiangxi
Abstract:The spider resource and fauna in Xiangshan uranium mine in Jiangxi were investigated, 453 samples were collected, identified that: they belong to 28 families, 75 genera and 143 species, among them, there are 1 new records species of Jiangxi, 1 new records family of Jiangxi, and 18 undefined species. The spider community structure diversity analysis showed that Marglef species richness index M was in the order: UCT>SCT>WNT>LNT>HNT>GWT>LWT>BNT; Berger-Parker dominance index d as follows: WNT>UCT>SCT=LNT>HNT>BNT>GWT>LWT; Simpson diversity index D as follows:WNT>UCT>LNT>SCT>HNT>GWT>LWT>BNT; Mackintosh evenness index E as follows: BNT>LNT>HNT>GWT>LNT>SCT>UCT>WNT. The spider predation function diversity analysis showed that Marglef species richness index M was in the order:MYP=COP>EUP>HYP>HEP>HOP>DIP>ORP>OLP>LEP; Berger-Parker dominance index d as follows: MYP>COP>HOP=HEP>EUP>HYP>ORP>DIP>LEP>OLP; Simpson diversity index D as follows: MYP>COP>HOP>HEP>EUP>ORP>HYP>DIP>OLP>LEP; Mackintosh evenness index E were: MYP=COP>EUP>HYP>HEP>HOP>DIP>ORP>OLP>LEP. In short, the spider types in Xiangshan uranium mine in Jiangxi had dominated by some common species of agricultural and residential district, and with a few features of spider species, whose ecological behaviour and species evolution often had no same.
