| Abstract: | 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. |
