摘要
于2006年夏季(6月)和冬季(12月)2次赴云南省西畴县对干洞和龙坪洞内的蜘蛛进行野外考察,共获标本290号,其中干洞内110号,经鉴定和分类,隶属9科18种;龙坪洞内180号,隶属10科20种.不论是种类组成还是相对数量,龙坪洞都比干洞要丰富.经物种多样性分析,从各光带不同季节的角度看,物种多样性指数最高是干洞夏季有光带(2.346 5),最低是龙坪洞冬季黑暗带(1.822 5);从夏、冬季平均值来看,最高是龙坪洞弱光带(2.248 3),最低是干洞黑暗带(1.891 9).干洞和龙坪洞同一光带蜘蛛多样性有明显的季节性,物种多样性指数均为夏季大于冬季;在夏季,两洞内蜘蛛物种多样性指数均具有比较明显的成带性,从大到小依次为有光带、弱光带、黑暗带.
In the fieldwork made in June and December,2006 in Xichou county of Yunnan province,110 spider specimens were collected in Gandong Cave,which were classified into 9 families and 18 species,and 180 were collected in Longpingdong Cave,which were classified into 10 families and 20 species.The species composition and relative quantity of spider in Longpingdong Cave were higher than in Gandong Cave.According to the analysis of species diversity and different light belts and seasons of different caves,the species diversity index of spider with light belt in summer of Gandong Cave（2.346 5） was the highest,and that with dark belt in winter of Longpingdong Cave（1.822 5） was the lowest.According to the average of the species diversity index of spider in summer and winter,the value of dim light belt in Longpingdong Cave（2.248 3） was the highest,and the value of dark belt in Gandong Cave（1.891 9） was the lowest.The species diversity of spider was obviously related to the seasonal dynamic changes in the same belt of Gandong Cave and Longpingdong Cave,namely,the diversity index in summer was higher than in winter.In addition,the species diversity of spider was related to different light belts of the two caves in summer,namely,the diversity index of spider appeared in the order of light beltdim light beltdark belt.
