Abstract

Abstract: In order to summarize the greening experience of island ring highway, based on the basic principles of the ideal point method, fifteen indexes of the landscape features, ecological functions and security features were selected as the evaluation indexes. The weight coefficient of each evaluation index was determined by the Delphi-ideal point method. A comprehensive evaluation model for highway greening quality was established based on the Delphi method and ideal point method. The range and distance of plus-minus grade classification of the highway greening quality given by the ideal point method were analyzed by data operating. And the results were graded at last. Combined with site investigation, the results show that the method is scientific and effective, also easy to operate.

Key words: road engineering, greening quality evaluation, Delphi-ideal point method

摘要： 为总结海南早期环岛高速绿化工程建设经验，以理想点法为基本原理，选取涵盖公路绿化景观功能、生态功能、安全功能3方面共15个指标作为评价指标，采用德尔-菲理想点法确定各个指标的权重系数，建立了基于德尔菲-理想点法的海南环岛高速绿化质量综合评价模型。通过数据运算，分析得出该高速公路绿化质量正负理想点判断范围和距离，最后对结果进行等级判别。结合现场调查，表明采用德尔菲-理想点法进行环岛高速G98绿化质量综合评价是科学有效的，且简单明了，易于操作。
