贵州沿河大水洞洞穴动物调查

Survey of Dashui Cave Animals in Yanhe County of Guizhou Province

2014年7月至8月,对贵州沿河大水洞内的动物进行了调查,共采集动物标本478号。经鉴定,隶属3门8纲10目18科20属23种,计算并讨论了该洞动物类群的群落结构及多样性。结果表明:多样性指数最高的是群落B(2.5588),而最低的是群落C(1.2718);相似性指数最高的是群落B-C(0.8050),最低的是群落A-C(0.2610);从多样性指数上看,三个群落中B群落为多样性最高的生物群落,由于人为因素的影响,群落A多样性反而次于群落B;从相似性指数上看,相邻群落比相隔群落的生物相似性高。

During July to August 2014, the author has surveyed the cave animals in Dashui cave of Yanhe County. 478 cave animals were collected, which belong to 3 phyla 8 classes 10 orders 18 families 20 genera 23 speices. Then the animal community structure and diversity of the hole is also calculated and discussed. The result shows that the highest index of diversity is community B（2.5588）, and community C（1.2718） is the lowest. The similarity index between community B and C（0.8050） is the highest, the lowest similarity index is between community A and C（0.2610）. In the index of biodiversity, the diversity of biological communities in B community is the highest in these three communities. The community diversity in community A is less that the community B dues to the influence of human factors. From the similarity index, the communities similarity of adjacent communities is higher than the separated communities.
