Considering both the vulnerability of water environmental and hazard to human beings,an integrated model for assessing the risk of water environmental pollution was developed based on fuzziness.In this model,vulnerability and hazard were both divided into six categories based on fuzzy theory.The fuzzy membership functions of vulnerability and hazard were built by the experts consultation and F statistical method.In order to obtain general risk of water environmental pollution,integrated evaluation was used to combine vulnerability and hazard together.The model was applied to 14 sections of Xiangjiang River,the pollution risk levels of which were intuitively expressed.In a sense,the developed model can provide new ideas and methods for the water resource management and the selecting of priority control section of Xiangjiang River.
