确定了不同路段的主要特征。探讨了公路建设生态影响的定量确定方法，并进行了实证分析。本文以大宝高速公路(大理至保山)和四小高速公路(思茅至小蒙阳)穿越纵向岭谷地区为例。对于没有重要物种保护的正常路段，引入生态系统健康评价方法，计算公路建设生态影响的总体范围。对于有感兴趣的植物或土壤的路段，选择指标，并使用回归分析和方差分析等数学方法确定影响范围。还从动物种群所需的最低生活面积和公路建设造成的碎片化方面讨论了对动物种群的影响范围。结果表明，公路建设影响带既有规律性又有异常性，两条样本公路不同地貌的影响幅度有很大差异；公路建设对路侧生态系统健康影响较大；对农田土壤因子的影响大于200m，如果考虑重要大型动物，影响距离可能超过1000m。
The major features of different road sections were identified. Methods quantitatively determining the ecological impact of highway construction were discussed, and a demonstration was presented. The Dabao highway (from Dali to Baoshan) and the Sixiao highway (from Simao to Xiaomengyang) passing through the Longitudinal Range-Gorge Region were used as examples in this paper. For the normal road sections having no important species to protect, a method of ecosystem health assessment was introduced to calculate the overall range of the ecological impact of highway construction. For the road sections having plants or soils of interest, indexes were selected and the range of impact was determined using mathematical methods such as regression analysis and variance analysis. The range of impact on animal populations was also discussed in terms of the minimum living areas required by animal populations and the fragmentation caused by highway construction. The results indicate that the zones impacted by highway construction were composed of both regular and anomalous figures, the range of impacts for different landforms of the two sample highways were substantially different; highway construction had dramatic effects on roadside ecosystem health; the impact on soil factors of farmland was greater than 200 m, and the distance may exceed 1000 m when important large animals were considered.
