摘 要：
为武功山国家级自然保护区山地草甸昆虫资源的合理利用及山地草甸害虫的防控提供参考,分别于2013年7—9月、2014年6—9月和2015年5—9月在武功山国家级自然保护区山地草甸6个典型生境(发射塔西北坡、发射塔东南坡、混生区、避风洼、云海客栈和吊马桩,海拔1 592~1 855m),采用"Z"字形网捕法对山地草甸昆虫种类和数量进行系统调查,并运用优势度指数、丰富度指数、多样性指数及均匀度指数分析不同生境的昆虫群落特征,计算相似性系数。结果表明:3年共采集昆虫标本7 895个,隶属于9个目,其中鞘翅目、半翅目和双翅目昆虫为优势类群,占总标本数的96.19%;4个指数在不同年份存在一定差异,但均在7月达最高或最低值;混生区(海拔1 657 m)与发射塔东南坡(海拔1 855 m)的相似性系数为0.249 9,处于极不相似水平,其他样地间的相似性系数在0.302 0~0.420 7,均处于中等不相似水平;海拔较高的发射塔东南坡与西北坡由于坡向差异,相似性系数仅为0.305 0,但两者与其他样地间相似性(0.249 9~0.323 0)低于其他4个样地相互间的相似性(0.359 7~0.420 7)。武功山国家级自然保护区山地草甸昆虫种类丰富,具有明显的时间性规律,其山地草甸昆虫群落的结构相对稳定,与气候、寄主植物的生境类型密切相关,并且还受海拔和坡向等多种因素的共同影响,每个生境都具有其独特的物种分布格局。

摘 要：
The species and quantity of mountain meadow insects in 6typical habitats of Wugongshan National Natural Reserve are systematically surveyed by the "Z"net capturing method from July to September,2013,June to September,2014 and from May to September,2015 and the insect community characteristics and similarity coefficients of different habitats are analyzed by dominance index,diversity index,diversity index and evenness index to provide a reference for rational utilization of mountain meadow insect resources and prevention and control of mountain meadow pest in Wugongshan National Natural Reserve.Results:7 895 insect specimens belonging to 9orders are collected during 3years.Coleoptera,Hemiptera and Diptera are the dominant species and their proportion is up to 96.19% of total specimens.There are some differencs in four indexes among the different years but their values all reach the maximum and minimum in July.The similarity coefficient between the mixed area(Alt.1 657 m)and the southeastern slope near the Launching Tower(Alt.1 855m)is 0.249 9at the very dissimilarity level.The similarity coefficient between other habitats is 0.302 0~0.420 7at the medium dissimilarity level.The similarity coefficient between the northwestern slope and southeastern slope near the Launching Tower is0.305 0 because of slope difference but the similarity(0.249 9~0.323 0)between the slope and southeastern slope near the Launching Tower and other habitats is lower than the similarity(0.359 7~0.420 7)between 4other habitats.There are abundant mountain meadow insect species and obivous timeliness regulation in Wugongshan National Natural Reserve.The relatively stable structure of mountain meadow insect community closely related to climate and the habitat type of host plants and is influenced by atitude,slope aspect and other factors also.Every habitat has the unique species distribution pattern.
