摘　　要：【目的】研究广西大明山国家级自然保护区(以下简称“大明山保护区”)直翅目昆虫多样性的海拔梯度格局及时间动态变化。【方法】根据大明山保护区内植被的垂直特征,在不同海拔的7个采样点设置马氏网,定期采集直翅目昆虫,通过查阅文献对其进行分类鉴定,并对多样性进行分析。【结果】大明山保护区共有直翅目昆虫19科155种,其中新纪录科5个,新纪录种21个。采集到的螽斯科(Tettigoniidae)昆虫最多,多样性指数和丰富度指数最高,属于优势类群。昆虫数量随海拔升高呈现先上升后下降的趋势,在海拔1110 m处的昆虫个体数最多,多样性指数和丰富度指数分别为0.96和3.27。8月的昆虫数量达到高峰期,多样性指数和丰富度指数分别为1.36和4.80。【结论】大明山保护区直翅目昆虫的分布受海拔和时间的影响。研究结果补充了部分新纪录科和种,为大明山保护区直翅目昆虫的生物多样性保护提供了基础数据。[Purpose]To describe the altitude patterns and temporal dynamics of Orthopteran diversity in the Damingshan National Nature Reserve,Guangxi(hereinafter referred to as“Damingshan Reserve”).[Methods]According to the vertical characteristics of vegetation in Damingshan Reserve,Malaise nets were set up at seven sampling points at different altitudes to collect Orthopteran regularly.The species were classified and identified through literature review,and the diversity was analyzed.[Results]There were 155 species belonged to 19 families in Damingshan Reserve,of which five new families and 21 new species were recorded.Tettigoniidae was the dominant group with the highest number of individuals,diversity index and richness index.The individuals number of Orthopteran increased first and then decreased with the increase of altitude.At an altitude of 1110 m,the individuals number was the largest,and the diversity index and richness index were 0.96 and 3.27,respectively.Orthopteran individuals number reached its peak in August,and the diversity index and richness index were 1.36 and 4.80,respectively.[Conclusion]Altitude and time affect the distribution of Orthopteran in Damingshan Reserve.The results of the study supplement some new record families and species,and provide basic data for the conservation of Orthopteran biodiversity in Damingshan Reserve.
