Abstract: Vegetation selection is the significant material basis in building forest of soil and water conservation and other types of forest, and it is an effective measure for restoration and rebuilding of degraded ecosystem. Based on the objective of vegetation selection alongside the regions of Xingfen highway of Hebei Province, we used analytic hierarchy process(AHP) to analyze 19 index factors, and comprehensively evaluated 89 plant species including trees, shrubs, and herbs. We selected ten main index factors in terms of selected plant species, and took the cluster analysis by SPSS statistical software. In the regions of each altitude, the proportion of drought resistance was the biggest for the weighted average of every index factor, and that of cold resistance changed the most greatly. Therefore, 11 herbs were ranked as level 1, 12 herbs were ranked as level 2, 8 shrubs were ranked as level 1, 13 herbs were ranked as level 2, 6 trees were ranked level 1, and 5 trees were ranked as level 2.
