延吉市不同类型绿地蝶类物种组成与多样性研究

Study on Species Composition and Diversity of Different Types of Green Space in Yanji City

为揭示在城市化过程中不同类型绿地对蝴蝶群落的影响,于2016年5~9月对延吉市郊区和市区6种不同生境类型中蝴蝶群落进行了调查。结果表明:共采集蝴蝶485只,隶属于5科16种。优势种为粉蝶科菜粉蝶和小灰碟科蓝灰蝶,6种生境类型中物种丰富度以天然林绿地最高,其次是过渡带绿地、河岸天然绿地、河岸人工绿地、金达莱公园、文化宫公园;多样性指数变化趋势为天然林绿地>过渡带绿地>河流人工绿地>河流天然绿地>金达莱公园>文化宫公园,可见不同人为干扰下的生境对蝴蝶种类丰富度及多样性有明显的影响。

In order to reveal the influence of different types of green space on the butterfly community in the process of urbanization, the butterfly community was investigated in 6 different habitats of Yanji City suburbs and urban areas in 2016 5--9 month. A total of 485 butterflies were collected belonging to 5 families and 16 species. The dominant species are Pieridae Pieris and small gray dieke blue butterfly. The species richness of the six habitat types is the highest in the natural forest Greenland followed by the transition zone, riparian natural green space, riparian artificial green space, jindal Park, cultural palace park green space〉The change trend of diversity index is the natural forest green space,transition zone〉riparian artificial green space,riparian natural green space〉jindal park〉cultural palace park green space. The results showed that the species richness and diversity were significantly affected by different habitats.
