针对建立生态型公路需要对现有公路近况有整体评价和把握,而目前公路评价缺少统一的评价模型、指标体系选取较分散的问题,研究对公路按照主因素做分段处理,选取5个评价指标,建立了公路精细化评价体系。为了得到GIS可视化分析参数,在指标量化过程中将评价指标分成主观指标和客观指标分别量化,并计算精细化评价参数,以两个评价参数线性之和作为最终评价参数。最后运用GIS空间分析对唐山环湖路进行了探索性可视化分析,为我国的公路建设和公路养护提供建议性方案。
For the establishment of ecological road need to have an overall evaluation and grasp of the current status of the highway, and now the lack of a unified evaluation model of highway evaluation, the index system to select a more dispersed issue, the study of the main road to do sub-treatment according to the main factors, select five evaluation Indicators, the establishment of a fine road evaluation system. In order to obtain GIS visualization analysis parameters, the evaluation index is divided into subjective index and objective index to quantify in the process of index quantification, and the refined evaluation parameters are calculated. The sum of the linearity of the two evaluation parameters is used as the final evaluation parameter. Finally, GIS spatial analysis is applied to exploratory visual analysis of Tangshan Lake Road to provide suggestions for highway construction and road maintenance in China.
