Abstract:

Insects have the niche of higher diversity and smaller scales in nature and the changing of their habitat is more sensitive,so the study of the insect diversity has a broad spectrum of biogeography and ecology probe function,and it is of great significance for ecological monitoring and protection.Artificial turf is mainly designed for landscaping in some areas.It is a unique vegetation type in scenic area.In MayJune 2011,a survey was conducted to investigate  insect diversity and related environmental factors in artificial turf of Lushan Mountain Scenic Area.By using diversity index and canonical correspondence analysis (CCA),the relationships between the insect diversity and related environmental factors were analyzed.A total of 472 individuals were collected,belonging to 11 Orders.Orthoptera and Lepidoptera were the dominant species,accounting for 5324% and 2278% of the total.Coleoptera and Hymenoptera were subdominant species,and the number of individuals accounted for 671% and 552%.Hemiptera,Diptera,Dermaptera,Phasmatodea and Odonata belonged to the common groups,respectively,accounted for 24%,36%,192%,144% and 168%. The remaining taxa were rare species,accounted for 1%.Through the analysis of diversity index,the artificial turf of diversity index showed a lower Shannon index (H),the higher Simpson index (λ) and Pielou index (J) compared with natural turf.CCA explained 100% of the correlations between the species and related environmental factors,suggesting that the occurrence of the species had close relations to the changes of related environmental factors.Among the environmental factors,trampling intensity,sample size,vegetation types were all great influence on the distribution of insect community.Through the research,some scientific reference about region protection and utilization of insect resources and setting of artificial turf were provided
