摘　　要：采用模糊逻辑方法对电子政务网络系统进行风险评估,对各风险因素从风险概率和风险影响两方面评判,并应用熵权系数法,客观地计算出每个风险因素的权重。通过实例说明该方法能很方便地求出电子政务网络系统的风险度,实际结果符合实际。Fuzzy logical method is applied to the risk assessment of the E-government network security.Each risk actor is estimated in the aspects of probability and the influence, The weight of the risk actor is calculated objectively by the method of entropy weight coefficient. The study of the case shows that the risk degree of the E-government network system can be conveniently found out with this method.The results conform to the actual situation.
