中文摘要：

植物种类筛选是营造水土保持林及其它林种的重要物质基础,是恢复与重建退化生态系统的有效举措。本文以河北邢汾高速公路沿线植被恢复和重建过程中植物种类的筛选为目标,应用层次分析法（AHP）对选定的19个指标因子进行分析,并对边坡沿线乔、灌、草89种植物进行了综合评价。同时选定10个主要指标因子,就不同海拔段筛选的植物种类进行聚类分析,结果表明：（1）各海拔段内,耐旱性所占权重值最大,耐寒性所占权重值变化最大;（2）综合性状评价等级为Ⅰ级的草本植物有11种,Ⅱ级有12种;灌木中Ⅰ级有8种,Ⅱ级有13种;乔木中Ⅰ级有6种,Ⅱ级有5种。

英文摘要：

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.
