The Chinese public will，when facing the risk of environmental pollution，show certain “strong action willingness” and “group action” inclination by choosing such actions as “giving their opinions through network and expressing their opposition”，“reporting to the media”，“reporting to the environmental protection organization”，“contacting more people to press the government”. To the “strong action willingness/group action” inclination of the public when they face the risk of environmental pollution and combining with the group events which often happen in the reality and aim at the realistic and possible environmental pollution harm，we think that we should pay attention to a new form of group event appearing in the Chinese society-“risk conflict”. Risk conflict is a group action which will happen when the public think that the new risks such as environmental pollution may bring about uncertain harm to them in the future. Generally，risk conflict happens not because the vested interest is harmed but because of the possible harm，namely，the risk in the future and the harm is uncertain and the risk is constructed. Risk conflict may，during the phase of transforming society in China，become a multiple mixed risk if it combines with such cases as that the public lack of trust to the local government，the government lacks of elasticity in its countermeasures，the public increase their risk awareness and sensibility and the system of risk experts lags behind.
