宁夏罗山国家自然保护区蝶类区系研究

2008—2009年对宁夏罗山进行了系统的蝶类标本采集,经分类鉴定出45种,隶属6科32属,其中以蛱蝶科种类最多,计8属14种,占总种数的28.13%,灰蝶科和眼蝶科次之,分别计9属10种和8属9种,各占总种数的25%.从世界动物区系的构成来看,组成以古北区和东洋区共有种及典型古北种为主体,占总种数的46.67%,中国动物地理区划中以华北+东北+蒙新+青藏+西南+华中+华南型居多,占22.22%.罗山和贺兰山的蝶类相似性系数较高,为0.46,罗山和六盘山的蝶类相似性系数较低,为0.19,3个地区蝶类组成的相似性分析,符合宁夏昆虫地理区划特点.

Studies on the butterfly fauna in Luo Mountain National Nature Reserve of Ningxia,China
