Abstract:

The aim was to establish landscape evaluation system and landscape evaluation model of expressway and to discuss landscape evaluation methods of expressway. Taking Harbin-Daqing expressway as an example, expressway landscape evaluation system were established, which were evaluated from three aspects of expressway the expressway’s landscape, cultural landscape along expressways and natural landscape at both sides of expressway. And landscape evaluation system of Harbin-Daqing expressway were set up on the basis of 15 second level indicators, 55 three level indicators. Evaluation criterion of second level indicator was established in reference to standards concerned and research data and weight were determined by AHP. Harbin-Daqing expressway landscape of qualitative and quantitative assessment was undertaken by methods of landscape composite index and fuzzy math evaluation method. The results showed that scores of overall landscape of majority sections of Harbin-Daqing expressway were between 6-7 scores and that of sections near Harbin City and Daqing City were higher than that of middle sections of Harbin-Daqing expressway. It resulted from low level greening and nursing. According to maximum membership principle of fuzzy evaluation method, the landscape quality was in general grade and results of two evaluation methods were the same. In view of the advantages and disadvantages of various evaluation methods, comprehensive index method and fuzzy mathematics method based on AHP fit for landscape quality evaluation of expressway.
