Studying Establishment of Evaluation Index System of Highway Ecological Greening

摘要

With defining the concept of highway ecological greening and based on the evaluation objective of highway ecological greening, we propose the principles and methods of evaluating highway ecological greening. The evaluation objects and contents are classified by taking the road section(greening section) as evaluation units,and indexes of safety function, ecological function,landscape function, operational performance and economic benefits are filtered out via some theoretical methods like AHP, Delphi method and statistic analysis, and then we establish evaluation index system and set evaluation criterion by using these indexes. This evaluation index system can scientifically and objectively measure and evaluate the present condition and the level of highway ecological greening development.
