Analysis Of Insect Network Behavior In Erhai Wetland

Wetland environments and insect diversity protections are hot research topics in recent years.The wetlands have great economic,social and ecological value,and the insects can be used as an indicator species for monitoring wetland environment.In order to understand the adaptability of the insect community to its habitat in the Erhai Lake wetland,to study insect network behavior and to evaluate the development status of the insect community and its habitat,this paper selected three experimental bases of the Eryuan East Lake,the Erhaiyue Lake and the Luoshijiang Wetlands,and applied the complex network theory to construct an insect ecological network.Multi-model and multi-dimensional insect ecological network and insect ecological time series dynamic network model.First,three models were defined using the theory of complex network topology.Based on the insect data samples and habitat data samples from November 2018 to October 2019,the insect populations,vegetation communities,and multi-dimensional information factors were used as network nodes.The rules of correlation and other rules were used as the edge of the network to construct the network topology model of the complex insect network,And the basic statistical characteristics of the network parameters were calculated.Secondly,through the analysis of the characteristic parameters of the network model,it is concluded that the network model conforms to the characteristics of the small-world and scale-free network,and the node degree distribution obeys the power-law distribution.The topological structure destruction method was used to simulate the dynamic evolution process of the network after the disappearance of insect species.The study found that the disappearance of important and endangered species in the network will have an exponential impact on the stability of the network.Thirdly,the effectiveness of the network model was verified through the study of the insect community structure characteristic index.This paper analyzed the composition of insect communities in wetlands in different regions,and found that the changes of human activities to the regional ecological environment directly affect the changes of the dominant groups of insects.Also the temporal evolution of insect community structure was discussed.The study found that the insect community structure of the three wetlands in Erhai Lake is similar.The original wetlands has strong stability,and the transformed wetlands have a certain self-regulation ability.Finally,combining the behavior analysis of the network model and the stability analysis of the insect community structure,the results showed that the evolution of the network has a natural universal law,and maintaining the stability of the network is a key strategy for insect ecological protection.Species richness and diversity index are important indicators to maintain the stability of insect community structure.The insect community in the Erhai Lake wetland has strong self-adaptive ability,which indicates that the current ecological environment of the Erhai Lake wetland is in a benign development,and suggestions for the construction of Erhai wetland and the stable development of insect community were put forward.
