Abstract: In order to evaluate the current state of insect ecological development in Erhai wetland, complex network theory is used to construct a topological structure model of insect ecological network with insect populations as network nodes and correlations as edges. By analyzing the characteristic parameters of the model, it is concluded that the insect ecological network conforms to the characteristics of small world and scale-free network, and the node degree distribution obeys the power law distribution. The method of destroying the topology is used to simulate the dynamic evolution of the network ecology. The study shows that the disappearance of important species and endangered species have an exponential impact on the stability of the network. The evolution of insect ecological network adapts to the natural universal law, and the maintaining network stability is the key strategy in the insect ecological protection.

Key words: insect ecological network, topological structure, universal characteristics, power law distribution, stability
