摘 要:为科学合理地评价绿色生态型城市道路,确立了绿色生态型城市道路概念,从设计合理性、道路功能效果、节能减排效果、绿化效果和环境保护效果五方面提出了绿色生态型城市道路评价指标体系,包括5个一级指标、14个二级指标与31个三级指标,并对各指标进行了阐述,确定了各指标的评价标准,提出了基于Spearman等级相关系数组合赋权方法与区间逼近方法的绿色生态型城市道路评价方法,并对中新天津生态城绿色生态型道路进行了评价。评价结果表明:中新天津生态城绿色生态型道路21个三级指标评定结果为优,其余10个指标评定结果为良;12个二级指标评定结果为优,其余2个指标评定结果为良;一级指标中设计合理性与环境保护效果评定结果为良,其余指标评定结果为优;绿色生态型城市道路评价指标集合到评价等级优的距离为3.82,为评价指标集合到各评价等级的最小距离,中新天津生态城绿色生态型道路评价结果为优,与实际相符,因此,绿色生态型城市道路评价指标体系与评价方法合理、可靠。In order to evaluate green ecotype city road scientifically and rationally,the concept of green ecotype city road was proposed,and the evaluation index system was set up from 5 aspects, namely,rationality of design,effect of road function,energy-conservation and emission-reduction effect,greening effect and environmental protection effect.5 first grade indexes,14 second grade indexes and 31 third grade indexes were elaborated, and their evaluation standards were determined.The evaluation method of green ecotype city road was established on the basis of Spearman rank correlation coefficient combination determining method and interval approximation method.The green ecotype road of China-Singapore Tianjin Ecotype City was evaluated by using the method and the index system.Evaluation result shows that for the road,21 third grade indexes are excellent and 10 third grade indexes are good.12 second grade indexes are excellent and 2 second grade indexes are good.2 first grade indexes,namely,rationality of design and environmental protection effect are good and the rest are excellent.The distance between the excellent evaluation grade and the evaluation index set of green ecotype city road is 3.82,and is smallest in the distances between the evaluation index set and the evaluation grades,which shows the green ecotype city road is excellent and the evaluation result is consistent with the reality.Therefore,the evaluation index system and the evaluation method are reasonable and reliable.34 tabs,21 refs.
