广西河边洞与水碱上洞内动物群落多样性初步研究

The preliminary study on cave animal communities diversity in Hebian and Shuijianshang caves in Guangxi

2007年7月对广西河边洞和水碱上洞洞内的软体动物、节肢动物和脊索动物进行了调查和标本的采集,河边洞共捕获标本180号,隶属3门5纲7目20科32种。水碱上洞共获标本254号,隶属3门5纲8目15科20种。经群落多样性分析,其多样性指数最高的是B群落(2.428 7);群落均匀度和优势度指数最高的分别是群落A(0.939 2)和群落F(0.429 2)。通过群落相似性分析,相似性指数最高的是群落D与群落E(0.400 0)。

The authors studied mollusca, arthropoda and chordata communities in Hebian cave and Shuijianshang cave in Guangxi province of China. 180 samples were collected in Bebian cave. They belong to 3 phyla 5classes 7orders 20 families 32 species. 254 samples were collected in Shuijianshang cave. They belong to 3 phyla 5classes 8orders 15 families 20 species. On the basis of calculation of diversity and similarity index between every two communities, results show that the highest index of diversity is community B （ 2. 4287 ）. The highest evenness and dominance indexes are community A （ 0. 9392） and community F （0. 4292） The highest similarity index is between community D and E （0. 4000）.
