摘要
2006年采用样地调查法研究了紫胶虫生境的蜘蛛群落多样性。据初步分析,共采获蜘蛛标本725头,计65种,数量以猫蛛最多,而种类则以园蛛最为丰富。在群落多样性方面,放养紫胶虫时间较长的人工林物种多样性指数和均匀度指数分别大于另3块样地,群落相似性系数为0.322-0.642。除放养紫胶虫时间最长的天然次生林和放养紫胶虫1 a的人工林之间的相似性为中等不相似水平外,其它两生境之间相似性都为中等相似或接近中等相似水平,反映了紫胶虫生境的蜘蛛群落不因紫胶虫放养干扰而减少。
Spider community diversity in Kerria spp. ecosystem was surveyed with the method of sample plot investigation in 2006. By preliminary study on the Spider community in Kerria spp. ecosystem, 725 spider individuals of 65 species were collected. In which, individuals were the most of Oxyopidae, species were the most abundant of Araneidae. In spider community diversity, it was higher that the diversity index in the plantation that has cultivated Kerria spp. for a longer time than others. Similarity indices in 4 plots were between 0.322 and 0.642, The spider communities of each 2 plots presented medium similarity or near medium similarity level except for that between the forest that has cultivated Kerria spp. for the longest time and the plantation that has cultivated Kerria spp. for one year. This was reflecting that though cultivating Kerria spp. increased more interferential factors, spider communities were not reduced in Kerria spp. ecosystem.
