Micro Community Flow Convergence Effect Research In Environmental Group Events

In recent years, environmental mass incidents showed the trend of large-scale protests. Technology risk caused by human pollution of the environment crisis,unfolding a series of environment public movement. Especially in the PX project mass incidents of environment has become the current social groups to express the important channel of environmental rights and interests. With the evolution of micro media communication, new type of information dissemination, space connection and interactive communication shape the individuals and groups of online relationships.Based on environmental risk and micro media under the micro community is increasingly highlighted. They not only become a chemical environmental health relative damage in the process of project construction, and access to the related information has also limited. In maoming PX incident, grass-roots government as improper, the usual reports of traditional media and micro media interactive connection, these factors will undoubtedly increase the weak position of micro community in the environmental risk.Based on the mass incidents "maoming PX" as the environment of a typical sample, the community of micro dynamic evolution as the main line, to explore the mechanism of cluster of behind the event and its risks. This article is based on maoming PX event occurred, origin and its empirical research, through the SPSS statistical software for data analysis, found that of the online community in the environment in the transfer of information resources sharing, caused the change of state such as cognition, emotion, behavior under the scale, formed "community flow aggregation effect" source power for the development of the incident. In the collective discussion, questionnaire survey and depth interview event reduction, Media information entropy, the environmental risk perception, community cohesion, three indicators, with these three indicators analysis online conversion of social stability,combined with survey data to study the cognitive mechanism of floating green, the emotional bonding mechanism and the behavior of linkage mechanism, the collective action risk system. Therefore, in order to realize disordered cluster to the orderly participation of benign development, under the public dissemination of micro community environmental protection alliance is a kind of reasonable and effective choice. Through the information community, the interests of the community and thevalue of community to bulid political life, dissolve the risk of micro flow community aggregation effect.
