摘要
为探究广西十万大山国家森林公园地区蝴蝶群落结构和多样性,选择了5种不同生境,每种生境设置一条长2 km的样线,于2016—2018年的4—9月定点监测各生境中的蝴蝶种类和数量,并分析了其多样性和相似性。共调查到5科88属155种3734只蝴蝶,其中檗黄粉蝶(Eurema blanda)和箭环蝶(Stichophthalma howgua)个体数量最多,分别占总个体数的16.60%和25.98%,为优势种;75种蝴蝶为稀有种。农林混作区生境中蝴蝶属和种数显著高于灌木林、湖岸带、针阔叶混交林和雨林生境;农林混作区和灌木林生境内蝴蝶的丰富度指数显著高于其他生境。不同生境相似性比较表明,灌木林和湖岸带生境蝴蝶的相似性系数最高,为0.42,灌木林和雨林生境蝴蝶的相似性系数最低,为0.29。不同月份调查到的蝴蝶属、种和个体数,多样性指数、均匀度指数、优势度指数和丰富度指数间无显著性差异。鉴于广西十万大山国家森林公园地区蝴蝶稀有种较多,今后仍需重视该地区环境的保护工作。
To explore community structure and diversity of butterfly in the Shiwandashan National Forest Park district of Guangxi,five different habitat types were selected in this region,and a2 km transect was set for each habitat.We investigated butterfly species and abundance from April to September in 2016-2018,and analyzed the diversity and compositional similarity of different habitats.A total of 3734 individuals from 155 species belonging to 88 genera and 5 families were collected.Eurema blanda and Stichophthalma howgua were the most abundant species,which accounted for 16.60% and 25.98% of the total abundance,respectively.The number of rare butterfly species was 75.The numbers of genus and species of butterfly in the habitat of mixed farming and forestry area were significantly higher than those in the shrub,lakeside area,conifer and hardwood mixed forest,and rain forest.Butterfly richness in the habitat of mixed farming and forestry area and shrub was significantly higher than those in other habitat types.The highest similarity coefficient was found between the habitats of shrub and lakeside area(0.42),while the lowest was between the habitats of shrub and rain forest(0.29).There was no difference of number of genus,species and individual,and diversity index,evenness index,dominance index and richness index among different months.Therefore,environmental protection of butterflies is recommended in Shiwandashan National Forest Park district due to the high richness of rare butterfly species.
