昆明金殿国家森林公园不同生境类型蝶类多样性

Butterfly Diversity of Different Types of Habitats in Jindian National Forest Park,Kunming

为了探讨蝶类生物多样性与生境类型之间的关系,对金殿国家森林公园不同生境类型中蝶类群落的势度指数为黑荆树林>云南松林>灌丛>湿地。湿地和灌丛之间的相似性系数最高。结果显示,植被多样性是影响蝶类分布的重要因子,黑荆树林对蝶类生物多样性有较大的负面影响。结构数量和多样性进行了调查研究。共采集蝴蝶标本591只,隶属8科37属50种。各生境类型蝶类种数、个体数量以及多样性指数大小为:灌丛>湿地>云南松林>黑荆树林;均匀度指数为湿地>灌丛>黑荆树林>云南松林;

A survey on butterfly diversity was conducted in four types of habitats in Jindian National Forest Park in Kunming in order to study the relations between butterfly diversity and different habitats in Yunnan. The specimens of 590 butterflies, belonging to eight families, 37 genera and 50 species were collected and identified. The number of butterfly species, individual number, and diversity index in shrubbery were the highest, followed by wetland, Pinus yunnanensis forest, and Acacia mearnsii forest. The evenness indexes of wetland, shrubbery, A. mearnsii forest, and P. yunnanens/s forest arranged in descending order. However, the dominance index of A. mearnsii forest was the highest, followed by P. yunnanens/s forest, shrubbery, and wetland. The similarity coefl3cient between wetland and shrubbery is the highest. Results show that vegeta- tion diversity is an important factor influencing the distribution of butterflies. A. mearnsii has a major negative effect on butterfly diversity.
