摘要
基于辐射传输模型PROSAIL,以多时相TM影像为数据源,定量反演高等级公路两侧植被的叶面积指数,并以叶面积指数变化对路域植被生长状况进行了动态监测。试验区研究结果表明:随着高速公路的开通运营,路域两侧植被的叶面积指数总体呈下降趋势,植被生长状况整体变差。研究结果为指导路域植被的生态恢复与保护提供了可靠的基础资料。
Based on simulations by the PROSAIL and multi-temporal TM image as information source,this research has ob- tained the vegetation Leaf Area Index on both sides of the high grade highway.It studied the dynamic changes of road vegetation growth status with LAI.The results show that road on both sides of the LAI decreased and vegetation growth became worse.It provides reliable basic data for guiding vegetation restoration and protection.
