In the ecosystem public opinion communication network composed of individual nodes and their propagation paths,each network node is not equally important in the process of ecological public opinion dissemination.It is of great significance for the control and management of ecological public opinion communication network to study and analyze the key network nodes and their mutual ecological public opinion communication relations in the ecological public opinion communication network.Based on the investigation of the complex network environment theory,this paper constructs the ecological public opinion communication network map.This paper measures the nodes of ecological public opinion communication network from the aspects of degree centrality,betweenness centrality,kernel centrality,eccentricity centrality,compactness centrality and eigenvector centrality.Finally,a simplified diagram of part of the structure of the ecological public opinion communication network is analyzed.The verification results show that different measurement methods and indicators can better measure and identify the key nodes in the ecological public opinion communication network from different angles.The results provide a reference for researchers and managers to analyze the ecological public opinion communication network and identify key nodes from the local and overall perspectives.
