摘要:

昆虫在自然界中占据着多样性更高、空间尺度更小的生境,对生境的变化也更敏感,开展昆虫多样性与环境因子的相关性研究对生态环境监测和保护具有重要意义。实验中我们选用庐山风景区不同人工草坪进行研究,对它们昆虫群落及环境因子特征进行了随机取样调查,采用多样性指数和典范对应分析(CCA)研究昆虫群落与环境因子之间的相关性。实验共收集了昆虫11目,472头,以直翅目和鳞翅目占优势,其个体数分别占捕获昆虫总个体数的5324%和2278%。CCA分析表明:昆虫与环境因子之间的相关性高达100%,提示环境因子变化影响昆虫的分布,从研究结果看,践踏强度、样地大小、植被类型都对昆虫群落的分布影响很大。为该区域昆虫资源的保护和利用以及人工草坪的设置等相关研究提供科学依据

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
