摘要:

为了解湖南高望界国家级自然保护区蝶类多样性本底及其影响因素, 2016年5月至2018年10月, 我们采用样线法对保护区内外的6种生境(保护区内4种, 区外2种)开展了20次蝶类多样性调查。共记录蝴蝶个体13,956只, 依照五科分类系统, 隶属5科113属239种, 其中湖南省蝶类新记录17种。区系成分以东洋种为主(139种, 占58.1%), 广布种次之(97种, 占40.6%), 古北种最少(3种, 占1.3%)。对不同生境的蝶类群落多样性指数进行分析后发现, 人为干扰程度和生境异质性共同影响蝶类多样性。不同生境相似性分析结果表明, 蝶类群落的相似度与人为干扰程度和植被类型差异密切相关。3年间, 蝶类多样性指数月度变化基本一致, 蝶类物种数、多样性指数与月均温间呈显著正相关, 与月降水量无相关性。综上, 蝶类多样性受到人为干扰程度和气象因子的影响。为保护蝶类资源, 建议保护好蝶类栖息地, 减少人为干扰。

Abstract:

In order to understand the butterfly diversity status and analyze its effective factors in the Gaowangjie National Nature Reserve, Hunan Province, we conducted a line-transect counting study for butterflies in 6 habitats (4 in protected reserve and 2 outside). We recorded a total of 13,956 individual butterflies and recorded 239 different species using the five-family classification system, which comprises 5 families and 113 genera. Seventeen species were newly recorded in the Hunan Province. Our analysis of zoogeography showed that Oriental species were dominant (139 species accounting for 58.1% of individuals), followed by the Widespread species (97 species, accounting for 40.6%) and the Palearctic species (3 species, accounting for 1.3%). We found that similarity in butterfly community was highly correlated with the degree of human disturbance and habitat heterogeneity. For three years, the butterfly diversity indices showed similar trends in monthly variation, and the species number and diversity index was positively correlated with mean monthly temperature rather than monthly rainfall. This indicates that butterfly diversity is directly correlated with human disturbance and meteorological factors. Therefore, we suggest that reduction of human disturbance and maintaining habitat quality may contribute to butterfly conservation of protected areas.
