According to the degree of controversy on environmental risk between scientific community and the lay，environment risk perception can be divided into two major categories，one is non-controversial environment risk perception and the other is controversial environment risk perception.Based on CGSS 2010 data，we discussed the effect of media use（media usage frequency and current news contact） and social network（interpersonal trust，interpersonal discussion，interpersonal network，belongingness）.The results of Paired-Sample T Test showed that the public perception of the non controversial environment risk was significantly higher than the controversial environment risks，while the latter's internal differences were significantly higher than the former.OLS regression model and the generalized ordinal logistic regression model show that the use of traditional media is still a main factor of environment risk perception，while the impact of internet is not significant.Non-controversial environment risk perception is influenced by media use and social network，while the controversial environment risk perception is influenced by the individual attributes and media use.
