Evaluation of Liuli Expressway Landscape Quality Based on Rough Set Theory
This paper constructed a system of indexes for evaluating Liuli expressway landscape, including 3 aspects of road-region environment landscape resources, aesthetics and ecological, totally 24 evaluation indexes. The rough set theory was introduced and first applied to evaluate expressway landscape quality. For calculating every index weight of Liuli expressway landscape quality accurately, index reduction principle was used to clear the redundancy indexes, and finally remained 15 indexes. Then, the evaluation index weight was determined by the method of attribute importance assignment weight. Finally, landscape quality indexes of the three landscape areas in Liuli expressway were obtained by calculating and analyzing.
