A study was conducted to evaluate high-grade highway landscape in a mountainous region in the east part of Hei-longjiang Province with the help of analytic hierarchy process and GIS, using remote sensing images ( SPOT5) as main da-ta resources. Each evaluation factor in the study area was overlaid to complete the landscape quality assessment of ecologi-cal environment in terms of the spatial overlay analysis of raster data. Results showed that the type II region played a domi-nant role due to its largest area, and slope farmland with an angle above 25 degrees gradually reconverted into forest or pas-ture to recover its original landscape ecological environment. The landscape quality of regional ecological environment was. at a comparatively good level, which could accurately and objectively reflect the actual situation of the road landscape.Some measures on recovering landscape ecological environment along high-grade highway in cold area were put forward based on the above results.%以遥感数据SPOT5为主要数据源,利用层次分析法和GIS技术分析相结合,对寒区高等级公路景观进行评价分析,利用栅格数据的空间叠加分析法将各评价因子进行叠加分析处理,完成对研究区域的景观生态环境质量评价.结果表明:Ⅱ类区域的面积最大,处于优势地位;坡度在25°以上的坡耕地逐步退耕还林还草,恢复了原来景观生态环境;区域景观生态质量属于相对较好的水平,其结果能较准确、客观地反映道路景观的实际情况.在此基础上,提出了寒区高等级公路沿线景观生态恢复措施.
