摘　　要：2007年7月21日-30日对广西岩头洞和下岩洞内的脊索动物、软体动物和节肢动物进行了调查，共获标本4300号，经鉴定和分类计67种，其中岩头洞内3590号，隶属3门5纲7目22科51种；下岩洞内710号，隶属3门5纲7目21科36种。本文主要研究了洞穴动物的多样性及群落结构。结果表明：物种多样性指数最高在群落E（2．6035），最低在群落F（1．4459）；相似性指数最高在群落B-D（0．3826），最低在群落A-F（0．0016）。The authors studied chordata,mollusca and arthropoda communities in caves Yantou of and Xiayan in Guangxi province. 4300 samples belonging to 3 phyla 5 classes 7 orders and 22 families were collected. There are 3590 samples .in Yantou cave belonging to 3 phyla 5 classes 8 orders and 22 families,and 710 samples in Xiayan belonging to 3 phyla 5 classes 7 orders and 21 families. Through research of the diversity and similarity of animal communities in different ray zones, we found that the highest index of diversity was community E（2.6053） and the lowest was community F（1.4459）. The similarity index between community B and community D was highest（0. 3826）the lowest was between community A and community F（0.0016）.
