摘　　要：运用层次分析和神经网络相结合的综合评价方法,从静态和动态2个方面对甘肃省内5条高速公路的可持续发展作了综合的实证分析研究.分析结果表明,5条高等级公路生态环境可持续发展趋势度值随着时间变化呈上升趋势,说明5条高等级公路生态环境在发展水平和发展协调度2方面均有较好的可持续发展态势.A sustainable development model of the ecosystem in highway and a synthetically measurement method combining analytic hierarchy process and neural network are proposed. From static state and dynamic state, the method is used to measure the sustainable development of the ecosystem of highway in. The results express that the change trend in the sustainable development measurements of the ecosystem in five highway of Gansu Province is enlarged as more as, and these are better trend between the criteria of sustainable development level and sustainable development synthesized measurements of the ecosystem in five highway of Gansu Province.
