| Abstract: | By introducing the basic elements,approach and count measure of the hierarchy analysis,using this analysis method to study the assessment of ecological-environmental impact of speedway,taking the Baoji-Tianshui Speedway as an example,the selection of the alternative schemes in assessment of ecological-environmental impact of speedway is analyzed.The result shows that this analysis method is not only an effectual method in solving the problem of selection of the alternative schemes in the assessment of ecological-environmental impact of speedway construction,but also improves notably the rationality,and it has a better consistency with the truth.At last,the advantage and disadvantage of this method in the assessment of ecological-environmental impact of speedway is discussed and a suggestion is provided in the study of the assessment of ecological-environmental impact of speedway for the future research. |
