研究昆虫群落对农田生境类型的利用状况,有助于深入理解农田生境类型与昆虫群落动态演变的潜在关系,为农田作物健康种植与高质发展提供理论依据. 本研究于2021年6月—2024年10月,采用样线法和样点法对江苏省镇江市戴庄村和常州市新康村农业耕种区的水稻田、菜地、果园、茶园生境中的昆虫多样性与群落波动变化进行监测调查. 利用昆虫群落多样性指数,包括丰富度、多度、香农威纳多样性指数、辛普森多样性指数以及均匀度指数来表征群落的物种多样性,以及利用谱系多样性阐明农业耕种区各种生境的昆虫群落多样性差异. 同时,基于多度加权的平均成对谱系距离(MPD)来表征群落的谱系结构,探究昆虫群落构建机制以理解昆虫群落的生态过程和动态变化,量化各多样性指标间的相关性. 物种丰富度在有机稻田最高,在常规菜地最低. 有机稻田、常规稻田、有机果园、常规果园、有机菜地、常规菜地、有机茶园、常规茶园的物种之间的亲缘关系比随机预期的更远,表现为群落发散,主要受到了种间竞争的作用; 新康基地表现为群落聚集,主要受到了生境过滤的作用. 研究农田生境昆虫群落的多样性及生态因子有助于掌握生境类型与农田昆虫群落的关系,为更好地发展有机农业生产提供理论帮助.

Studying the utilisation status of insect communities on farmland habitat types can help to deeply understand the potential relationship between farmland habitat types and the dynamic evolution of insect communities,and provide a theoretical basis for the healthy cultivation and high quality development of farmland crops. In this study,from June 2021 to October 2024,we monitored and investigated the changes of insect diversity and community fluctuations in the habitats of paddy fields,vegetable fields,orchards,and tea gardens in the agricultural cultivation areas of Daizhuang Village,Zhenjiang City,Jiangsu Province,and Xinkang Village,Changzhou City,Jiangsu Province,by using the sample line method and the sample point method. Insect community diversity indices,including richness,multiplicity,Shannon Wiener's diversity index,Simpson's diversity index,and evenness index,were used to characterise the species diversity of the communities,as well as spectral diversity to elucidate the differences in the diversity of insect communities in various habitats of the agricultural cultivation area. At the same time,the multivariate weighted mean pairwise pedigree distance(MPD)was used to characterise the community's pedigree structure,to explore the mechanisms of insect community construction to understand the ecological processes and dynamics of insect communities,and to quantify the correlation between the diversity indicators. Species richness was highest in organic rice fields and lowest in conventional vegetable fields. Species in organic paddy field,conventional paddy field,organic orchard,conventional orchard,organic vegetable field,conventional vegetable field,organic tea garden,and conventional tea garden were more distantly related to each other than randomly expected,and showed community dispersal,which was mainly affected by interspecific competition,while the Xinkang base showed community aggregation,which was mainly affected by habitat filtering. Studying the diversity and ecological factors of insect communities in farmland habitats can help to grasp the relationship between habitat types and insect communities in farmland,and provide theoretical help for better development of organic agricultural production.
