摘要
对龙天洞和郑家大洞内的软体动物、节肢动物和脊索动物进行了观察和采集，两洞共获标本８４７个，隶属３门６纲１５目２８种。并对两洞的动物群落进行了研究，结果多样性指数最高的是群落Ａ（２．２３０８），而最低是群落Ｆ（０．９４０４）；相似性指数最高是群落Ｅ－Ｆ（０．６３６３），而最低是群落Ｄ－Ｆ（０．１５５２）。此外，还对两洞的动物季节数量动态和空间分布进行了分析。
In June 1996, January 1997 and May 1998, the authors studied Mollusca, Arthropoda and Chordata communities in Longtian cave and Zhengjia big cave at Anshun county, Guizhou province of China. 847 samples, belonging to 3 phyla 6 classes 15 orders 28 families, were collected. They can be divided into 6 communities as follows: A.Tortaxis mandarinus + Orthomorpha community B.Diestrammena marmorata + Sypna picta community C.Hipposideros armiger + Diestrammena marmorata community D.Tortaxis mandarinus + Euphaedusa community E.Diestrammena marmorata + Spilobolus community F.Spilobolus + Diestrammena marmorata community On the basis of calculation of diversity and dominance indexes of every community and similarity index between every two communities,the results show that the highest index of diversity is community A (2.2308) and community F (0.9404) is the lowest, and the highest index of dominance is community F (0.6718) and community D (1.896) is the highest. The similarity index between community E and F (0.6363) is the highest, the lowest is between community D and F (0.1552). Descending trend of the categories and numbers of cave animals in winter was also found.
