摘　　要：植被是环境的重要组成因子,植被的保护和恢复是公路生态环境建设的核心。而生态环境的传统评价方法无法对植被环境做出全面、及时的反映,无法满足实际工作需求。利用遥感的光谱性优势,以京港澳高速长潭段路域为试验区,结合物理方法及数学分析,建立高等级公路路域植被健康指数模型。结果表明:模型计算结果与现场试验结果吻合较好,可有针对性地指导路域环境的防治,为路域生态环境遥感监测的业务化运行奠定坚实基础。Vegetation plays an important role in environment, so the protection and recovering of vegetation are the core of highway ecological environment construction. The traditional evaluation methodology of eco- logical environment is not able to reflect the vegetation environment generally and timely, so the practical work can not be satisfied. With the Changtan section of G5 highway as the test site,this study makes full use of the spectral advantage of RS,combines with physical method and mathematical analysis to build the HVHI model. The model calculating result can fits to the field test result well,which can conduct the pre- ventive treatment of highway environment and lay the solid foundation for the operation of highway envi- ronment RS monitoring.
