The construction of highway ecological landscape is an important part of highway entity and an iconic feature of scenic countryside and ecological garden city, which plays an important role in the process of achieving social and economic sustainable development. The efficient index system and method is a basic measurement for the assessment of the interior quality and its associated outer environment. By taking five arterial highways (G15, G228, G204, S334 and S335) in the territory of Nantong City, Jiangsu Province as the case, an evaluation system containing quantitative and qualitative indices was developed to deal with the ecological landscape quality. The system composed of 12 evaluation indices which were divided into three categories including ornamental value, ecological efficiency, and safety design. Based on the survey and calculation of the raw data, the variable matrix was established and analyzed with principal component (PC) analysis. The results showed that the equation of highway greening ecological evaluation score was H=0.694×PC1+0.191×PC2+0.115×PC3, and scores of 5 highways ranked in the ordination of G204 > G15 > S334 > G228 > S335. The results would provide methods and references for efficient evaluation of highway landscape.
公路生态景观建设是公路实体的重要组成部分，也是美丽乡村和生态园林城市的标志性特征，在实现社会经济可持续发展过程中发挥着重要作用。高效的指标体系和方法是评估内部质量及其相关外部环境的基本尺度。以江苏省南通市境内的五条干线公路（G15、G228、G204、S334和S335）为例，构建了一个包含定量和定性指标的评价体系来处理生态景观质量。该体系由12个评价指标组成，分为观赏价值、生态效益和安全设计三类。在对原始数据进行调查和计算的基础上，建立了变量矩阵并采用主成分分析进行分析。结果表明，公路绿化生态评价得分方程为H = 0.694×PC1 + 0.191×PC2 + 0.115×PC3，五条公路的得分排序为G204 > G15 > S334 > G228 > S335。研究结果可为公路景观的高效评价提供方法和参考。
