应龙山森林公园不同生境昆虫群落多样性分析

Diversity of Insect Communities in Different Habitats of Yinglongshan Forest Park

[目的]探明应龙山森林公园昆虫多样性及生境情况,为保护生态系统提供科学依据。[主法]于2020年4-9月,采用样线法、黄盘法、网捕法在应龙山森林公园进行昆虫采集,按生境类型对采集到的昆虫进行种类鉴定和数量统计。[结果]共记录昆虫11目43科82属88种,共3593只,优势种25种,其中采集到的鞘翅目种类最多,占29.39%,包括4种生境:林缘、灌丛、草甸、湿地,不同生境的昆虫个体数量为灌丛>草甸>林缘>湿地,且昆虫对于不同生境有相应的选择倾向,人为干扰较少的生境中昆虫种类丰富,昆虫多样性高且群落稳定性好。[结论]应龙山的昆虫多样性保护应首先倾向于对湿地、林缘区域采取措施。

[Objective]To explore the insect diversity and habitat in Yinglongshan Forest Park and provide scientific basis for the protection of ecosystem.[Method]Insect collection was carried out in Yilongshan Forest Park from April 2020 to September 2020 by wire sampling,yellow disc and net trapping methods,and species identification and quantitative statistics were performed on the collected insects according to habitat type.[Result]A total of 3593 insects belonging to 82 genera,43 families,11 orders were recorded in this survey,with 25 dominant species.Among them,the species of Coleoptera were the most,accounting for 29.39%,including four habitats:forest edge,shrubbery,grassy marshland and wetland.The order of individual number of insects in different habitats was shrubbery>grassy marshland>forest edge>wetland.The results of population analysis showed that insects had a tendency of selection for different habitats.There were abundant insect species,high insect diversity and good community stability in the habitats with less human disturbance,such as grassy marshland and shrubbery.[Conclusion]Insect diversity conservation should be favoured at first for wetlands,limbic areas where measures are to be taken.
