摘要
通过四次对青冈林洞、洗线洞和水响洞的调查,共获37种动物。各种类数量优势分别为有光带的蚁蛉幼虫、蕈蚊,弱光带和黑暗带水域的红点髭蟾蝌蚪以及洞壁的斑灶马。2001年10月和2003年3月,青冈林洞、洗线洞和水响洞分别有动物群落15、13和10种类型,优势群落为斑灶马、红点髭蟾蝌蚪和蚁蛉幼虫。动物的取食、隐蔽、繁殖、栖息等环境在不同时期的变换引起这一区域洞穴动物在种类、数量和空间分布等的变化,人类活动则加大了生境的差异。食物-陷阱法可用于部分动物的相对数量的调查。
Thirty seven species of animal have been found in Qingganglin,Xixian and Shuixiang caves through four times of investigation. The animals in number dominance of each species are Myrmeleom formicarius(larva) on the ground with strong-light at the cave entrance,Mycetophilidae on the cave wall with weak-light and Oreolalaxrhohostig metus(tadpole) in waters and Diestrammena marmorata on the cave wall without light or in darkness. There are 15,13 and 10 types of cave fauna respectively in Qingganglin cave,Xixian cave and Shuixiang cave in Ocetober, 2001 and March, 2003. The dominent fauna are Diestrammena marmorata,Oreolalaxrhohostig metus(tadpole)and Myrmeleom formicarius(larva). Changes in animal species,numbers and spatial distribution are caused by changes of feeding,hiding,reproducing and resting habitats of the cave animals. Human activity has aggravated the difference of habitats. The method of Food-Entrap can be used in investigation on the relative quantity of some animals.
