Correlation analysis between plant communities and insect communities in urban forests
In order to clarify the composition and relationship between plant community and insect community,and provide theoretical basis for improving biodiversity and pest control.In this paper,five plant configuration types(Ⅰ-ecological base forest,Ⅱ-colorful flower forest,Ⅲ-forest grassland,Ⅳ-forest orchard and Ⅴ-near-natural forest)were selected as the research objects in Xiongan New Area,and the correlation between plant community and insect community was determined by using community investigation methods and typical cor-relation analysis.The results showed that there were 48 species of 20 families,35 genera and 20 families in the 5 plant configuration.Ⅰ plant community diversity index and richness in-dex were higher,dominance index was lower,and stability was better,which was signifi-cantly different from Ⅳ.Ⅱ,Ⅲ and Ⅴ had no significant difference except evenness index.There were 336 species of insects in 12 orders and 100 families.According to the index of in-sect community characteristics,Ⅰ reflected relatively stable community structure,which was significantly different from Ⅳ,and had no significant difference from other configura-tions,Ⅱ,m and Ⅴ had no significantly difference,and the overall trend of insect communi-ty characteristics was consistent with that of plant community.Typical correlation analysis showed that Ⅰ plant communities had significant correlation with insect communities,while the other four plant communities had no significant correlation with insect communities.Conclusion:The plant community and insect community structure of the plant configuration were stable,and there was a significant correlation between the plant community and the in-sect community.Different plant configurations led to different degrees of differences in insect communities.
