摘　　要：对贵州省9个主要自然保护区的大叶蝉亚科昆虫进行了整理,用Sorenson指数分析了各保护区之间的物种相似性,用Pearson系数分析了各保护区之间的物种相似性与地理距离、经纬度、海拔、植物种数和保护区面积的相关性。结果表明:贵州省9个自然保护区共有大叶蝉亚科昆虫87种,占贵州省已知大叶蝉亚科昆虫种类的94.6%,占全国已知大叶蝉亚科昆虫种类的35.8%;从属级相似性看,各保护区之间的相似性均较高,多为中等相似或极为相似;从种级相似性看,大沙河与宽阔水、梵净山保护区之间为极为相似,草海与其他保护区之间均为极不相似,其余保护区之间均为中等不相似或中等相似;各保护区大叶蝉亚科昆虫物种的相似性与地理距离、经度、最低海拔和海拔落差呈极显著负相关,但与纬度、最高海拔、植物种数和保护区面积的相关性不明显。The data of Cicadellinae （Hemiptera： Cicadellidae） on 9 main nature reserves in Guizhou province were arranged, composition varied of the Cicadellinae insect among the different nature reserves and the effects of environmental factor on similarities were studied by using Sorenson index and Pearson relation analysis. The results showed that 87 species of Cicadellinae were recorded on 9 main nature reserves in Guizhou province, accounting for 94.6% of Guizhou province＇s known species, and 35.8% of China＇s known species. At genus level, Sorenson indexes of Cicadellinae insect were higher between the nine reserves and varied in range of 0.5-1. At species level, Sorenson indexes of Cicadellinae insect were variable, varied in range of 0.75-1 between Dashahe and Kuankuoshui, Dashahe and Fanjingshan, less than 0.25 between Caohai with other nature reserves, the rest in range of 0.25-0.75. The correlation analysis revealed that geographic distance, longitude, the lowest altitude and various elevation had a significant influence on similarities, other environmental factors had no significant impacts on similarities.
