摘要
对贵州和尚洞内的软体动物、节肢动物和脊索动物进行了观察和采集，共获标本３５０号，隶属３门５纲１３目１９科。研究了不同光带内洞穴动物的多样性。结果表明，洞内物种丰富，多样性和均匀度指数最高均在有光带，其指数分别为３．５５１１、２．２９６４和０．７７９９；优势度指数在黑暗带最高（０．３７５６）；相似性指数最高在弱光带与黑暗带之间（０．６３３８）。此外，还对洞穴动物的分布进行了分析。
From May 1997 to May 1998, the authers studied mollusc, arthropoda and chordata diversity in Huoshanng cave in Guiyang City, Guizhou Province of China. The sum of collected samples is 350, belonging to 3 phyla 5 classes 13 orders 19 families. The diversity of cave animals is studied in different light belts. The result of diversity analysis has shown that species richness index (3.5511), diversity index (2.2964) and evenness index (0.7799) is the highest in light belt. The highest dominance index (0.3756) is found in lightless belt. The similarity index (0.6338) is between reflex belt and linghtless belt. The decreasing trend of the category and number of animals is shown in every belt in winter and spring. Light and humidity are the important factors of horizontal distribution of cave animals.
