中文摘要：

外来工聚居社区的社会风险是制度因素、环境因素及个人因素组成的复合因素的反映。三种因素的交叉组合，形成七个区间，社会风险相应可分为七个小类，并归为三个类型。三个因素的高度叠加区的社会风险系数较高。普通叠加区次之，单独因素区最后。七种类型的社会风险发生的可能性大小还与三种因素的力量格局有关，它们共同决定着社会风险发生的几率，并成为甄别风险的重要依据。

英文摘要：

The social risk of migrant workers community is a composite reflection of the institutional factors, environ- mentgl factors and personal factors. With cross-comhinations of three factors form seven intervals, social risk corre- spondingly can be divided into seven categories and classified into three types. Generally, in the dense overlay district of the three factors, the social risk is the highest, followed by ordinary overlay district, and then by separate factors. The size of the seven types of social risk is related to the likelihood of the power structure of the three factors. Super- position condition and strength of the pattern of risk determine the probability of social risk occurrence of the migrant workers community, and also become an important evidence of the screening risk.
