摘要
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。
A study was conducted to evaluate high-grade highway landscape in a mountainous region in the east part of Heilongjiang Province with the help of analytic hierarchy process and GIS, using remote sensing images （ SPOT5 ） as main data resources. Each evaluation factor in the study area was overlaid to complete the landscape quality assessmenf of ecalogical, environment in terms of the spatial overlay analysis of raster data. Results showed that the type Ⅱ region played a dominant role due to its largest area, and slope farmland with an angle above 25 degrees gradually reconverted into forest or pasture 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.
