黑龙江省帽儿山蝶类群落多样性研究

摘要

选取老道沟(Ⅰ)、东北林业大学实习基地人工种植园(Ⅱ)、东北林业大学实习基地东山(Ⅲ)3个样地,于2011年8月中旬和2012年7月上旬对帽儿山地区堞类群落进行调查研究.共采集蝶类1 028只,隶属5科29属47种,其中蛱蝶科的种类数(24)种,是该区优势类群;凤蝶科(20只)只有2种,是该区稀有类群.分析3个生境中蝶类多样性指数、物种丰富度、优势度指数和均匀度指数.结果表明,生境条件变化对蝶类多样性产生明显影响,蝶类多样性指数与均匀度变化一致,与优势度指数呈负相关性.%The butterfly species in Maoer Mountain of Heilongjiang was studied based on the collection in three samples:(Ⅰ) Laodaogou,(Ⅱ) The plantation of teaching base of the Northeast forestry university (Ⅲ) East mountain of teaching base of the Northeast forestry university in middle ten days of August 2011 and early ten days of July 2012.A total of 1 028 butterfly specimens were collected,of which 47 species in 29 genera under five families were identified.Nymphalidae was the dominant family,with 24 species.Papilionidae contained only 2 species,which was regarded as the rare species.The diversity index,the specific richness,the dominance index,the evenness index and the similarity coefficient of 3 habitats were calculated and analyzed.The results showed that the change of the environmental quality influenced the diversity of butterfly remarkably.The index of diversity of butterfly in Maoer Mountain was correlated with the index of evenness and inversed with the index of dominance.
