摘要
香蕉园蜘蛛群落组成隶属于17科48属71种。跳蛛科、球蛛科、狼蛛科、肖峭科、皿蛛科和抚蛛科是优势科。种类以跳蛛、数量以抚蛛最多。群落垂直分层结构明显。广西抚蛛与草间钻头蛛,幼豹蛛与类奇异獾蛛分别是植株叶片和地面群落的优势种群。群落多样性地面高于植株。植株层间的相似性高于植株与地面之间的相似性。植株叶片上的蜘蛛与昆虫数量消长相关极显著。
Spiders community in Banana fields include 17 families , 48 genera, 71species. Salticidae, Theridiidae, Lycosidae, Tetragnathidae, Linyphiidae and Uloboridae were dominant families. Among them, species number of Salticidae and individual number of Uloboridae were found meximun, respectively. The vertical stuctures of community are very significant. Uloborus guang.riensis and Hrlypkantes gramimcola in the plant leaves, Pardosa pusiola and Trochosa ruricolides in the land su-face were dominant species, respectivily. The community diversities of the land suface were found heigher than that of the plant leaves. The similar coefficient between on different stratum in the plant leaves heigher than that between on different stratum in the leaves with the land suface . The numerical dynamics beween the spiders and insects were significant Correlation in the plant leaves.
