Evaluation Index System Of The Highway Ecosystem

The construction of the highway brings the fast development of the economics and the pressure to the ecological environment. This paper, based on the highway ecosystem assessment the theory (ecology, traffic engineering, the sustainability, system dynamics), uses the thoughtfulness of the pressure-state-response framework model for reference, and sets up the indicator set frame model of the highway ecological assessment. According to the frame model it designs the ecosystem assessment indicator set and gives the computation to the indicators. At the same time the highway ecosystem assessment model is set up. Then the changes of the ecosystem state is considered under the pressure and the response-pressure in the construction period and the run period of the expressway. At last the paper explored the example of the highway from Laoyukou in Hu city to Huaishuguan in Yang city.
