摘要
根据植被类型与海拔的变化,在王朗自然保护区选择了5个不同生境作为监测点。分别于2007年7、8、10月,2008年4月,对选定的监测对象进行采集,共采集标本24876头,1000余种,隶属于3目7科,其中优势种群为尺蛾科、夜蛾科、姬蜂科、步甲科,其个体总数分别占69.51%、23.23%、5.03%、1.9%;鳃金龟科、叩头甲科以及瓢甲科仅占了0.33%。利用物种丰富度指数(S)、多样性指数(H′)、均匀度指数(J)对不同的群落进行统计,发现各监测对象的多样性随着时间与空间的变化呈现出不同的变化趋势。
5 different habitats were chosen as monitoring sites in Wanglang National Nature Reserve, according to vegetation and elevation. 24 876 insects were collected in July, August, October 2007, and April 2008. There were about 1000 species belonging to 7 families of 3 orders, of which, Geometridae accounted for 69.51%, Noctuidae 23.23%, Ichneumonidae 5.03%, Carabidae 1.9%, and 0. 33% to others. Based on the statistics of species richness （S）, biodiversity （H′）, and evenness index（J）, biodiversity of monitoring objects were found taking on different trends along the time and space changing.
