摘　　要：2010—2011年共分4期采用样线法对东莞银瓶山自然保护区蝶类群落进行系统调查。结果表明:银瓶山蝶类群落由9科31属42种组成;个体数量最多的科为粉蝶科,其次为凤蝶科、蛱蝶科和眼蝶科;Margalef丰富度指数从高到低依次为蛱蝶科、凤蝶科、粉蝶科、眼蝶科、弄蝶科、灰蝶科、蚬蝶科、斑蝶科和环蝶科;7、5月调查到的蝶类种类和数量较多,其次为11月,2月的蝶类种类和数量都明显减少;Shannon多样性指数从高到低依次为7、5、11、2月。珠三角核心区域社会经济发展对东莞银瓶山自然保护区生态环境的影响较大,蝶类群落的栖息环境恶化,其生物多样性急剧下降,城市化发展过程中要减少人类活动对自然环境的干扰和破坏,加强对生物多样性的保护与恢复。A fourtime investigation with line transect method was conducted on the butterfly diversity in Yinpingshan Nature Reserve of Dongguan in 2010-2011. Fortytwo species of butterfly belonging to 31 genera and 9 families were identified. Pieridae had the most abundant individuals, followed by Papilionidae, Nymphalidae, and Satyridae. Nymphalidae was the highest in species richness, followed by Papilionidae, and Pieridae. The Shannon index and abundance of the butterfly were the highest in July, followed by in May, November, and February. Due to the rapid social and economic development, the Yinpingshan Nature Reserve suffered great environmental stress, leading to the significantly lower species richness and abundance of butterfly than that in the peripheral areas of the Pearl River Delta. It was suggested that more attention should be taken to restore and improve the environmental quality during the process of urban development, so that the biodiversity could be effectively protected.
