摘要
路域生态系统监测是掌握路域生态系统质量状况和变化原因的基础和关键环节,对于路域生态环境保护与可持续发展具有重要意义。由于具有大范围、多时相、高精度和综合性等优势,遥感技术逐渐成为路域生态监测的主流手段。本文从景观格局遥感监测、植被状况遥感监测和物种多样性监测3个方面,回顾国内外相关方面的研究进展,总结研究趋势,指出现阶段研究面临的主要问题与挑战,并提出未来发展展望。研究表明:(1)路域生态系统遥感监测涵盖方面众多,研究成果丰富,不同方法具有各自的应用优势和不足;(2)路域生态系统遥感监测目前仍面临着针对公路建设期监测少、监测评价指标针对性弱、基于公路特点的遥感监测较少、路域范围划定不明确等诸多挑战。因此,未来研究应从多维角度,设立多项指标对路域建设期生态状况进行评价,根据陆路交通设施的线性工程特点,发展具有针对性的监测技术,提升监测效率和实时性。
Road ecosystem monitoring is the foundation and key link for understanding the quality status and causes of changes in road ecosystems,and is of great significance for road ecological environment protection and sustainable development.Due to its advantages such as large-scale,multi-temporal,high-precision,and com⁃prehensiveness,remote sensing technology has gradually become the main means of road ecological monitoring.This article reviews the domestic and international research progress from three aspects of remote sensing moni⁃toring with landscape pattern,vegetation status and species diversity monitoring,summarizes research trends,points out the main problems and challenges faced by current research,and proposes future development pros⁃pects.Research has shown that(1)remote sensing monitoring of road ecosystems covers a wide range of as⁃pects,with rich research results.Different remote sensing monitoring methods have their own advantages and disadvantages in application.(2)At present,remote sensing monitoring of road ecosystems still faces many challenges,such as insufficient monitoring during road construction,weak targeting of monitoring and evalua⁃tion indicators,limited remote sensing monitoring based on road characteristics,and unclear delineation of road boundaries.Therefore,future research should establish multiple indicators from a multidimensional perspective to evaluate the ecological status of the road construction period.Based on the linear engineering characteristics of land transportation facilities,targeted monitoring technologies should be developed to improve monitoring ef⁃ficiency and real-time performance.
