济南市绣源河低碳生态景区鸟类及昆虫多样性调查研究

Investigation of Bird and Insect Diversity in Xiuyuan River Low-Carbon Ecological Scenic Spot in Jinan

于2023年6月开展对济南绣源河低碳生态景区鸟类及昆虫多样性的调查工作,在景区内随机选取样地,昆虫调查采用网捕法、黄盘法、灯诱法等,鸟类调查采用样线法、样点法,对调查数据进行整理分析。结果表明:共记录到21种鸟类,隶属8目16科21属,其中以雀形目鸟类居多,麻雀数量最多,大山雀其次,首次出现在景区的鸟类包括金眶鸻和黑翅长脚鹬,景区内各目鸟类优势度指数、均匀度指数与多样性指数变化趋势一致;共观察到302种昆虫,涉及11目124科,各目昆虫优势度指数、均匀度指数与多样性指数变化趋势一致。但鞘翅目桃红颈天牛、同翅目斑衣蜡蝉捕捉数量明显高于其他昆虫,可能有爆发趋势。指出了济南绣源河低碳生态景区鸟类、昆虫群落均有较高稳定性,鸟类以雀形目为主,且金眶鸻和黑翅长脚鹬的出现说明景区生态环境治理效果明显,但昆虫中桃红颈天牛、斑衣蜡蝉数量过多,有成灾风险,应及时进行防治。

The diversity of birds and insects in the Xiuyuan River low-carbon ecological scenic spot in Jinan was investigated.Methods:In June 2023,a survey on the diversity of birds and insects in Jinan Xiuyuan River low-carbon ecological scenic spot was organized and carried out.Sampling sites were randomly selected in the scenic spot.Net trapping method,yellow disk method and lamp lure method were used for insect survey.Line transect method and point sampling method were used for bird survey,and the survey data were sorted and analyzed.Results:A total of 21 species of birds were recorded in this survey,belonging to 8 orders,16 families and 21 genera,among which the majority were passeriformes,and sparrows were the most numerous followed by great tits.The birds that appeared in the scenic spot for the first time included the Charadrius dubius and the Himantopus mexicanus,and the trends of the dominance index,evenness index and diversity index of birds of each order were consistent.A total of 302 species of insects were observed in this survey,involving 11 orders and 124 families.The dominance index,evenness index and diversity index of insects in each order showed the same trend.However,the capture quantity of Aromia bungii Faldermann and Lycorma delicatula was significantly higher than other insects,which may have an outbreak trend.Conclusion:The bird and insect communities in the Xianyuan River low-carbon ecological scenic spot in Jinan are relatively stable,and the birds are mainly passerines,and the appearance of the Charadrius dubius and Himantopus mexicanus indicates that the ecological environment control effect of the scenic spot is obvious.However,there are too many Aromia bungii Faldermann and Lycorma delicatula,which have the risk of disaster and should be prevented in time.
