为了综合评价杉木无性系抗旱性，在干旱胁迫条件下对不同杉木无性系抗旱性指标测定基础上，应用层次分析法（AHP），建立了杉木无性系抗旱性选择的递阶层次结构，对杉木无性系抗旱性进行了定量筛选．结果表明，不同参试杉木无性系抗旱性强弱的综合排序为：115号＞268号＞197号＞29号＞277号＞32号，其中以115号无性系抗旱性最强，可以在干旱林地上推广．
In order to comprehensively evaluate the drought resistance of Chinese fir clones, based on the determination of drought resistance index of different fir clones under drought stress, the hierarchical structure of drought resistance of Chinese fir clones was established by using analytic hierarchy process (AHP) Clonal drought resistance was screened. The results showed that the comprehensive ranking of the drought resistance of different Chinese fir clones was: 115> 268> 197> 29> 277> 32, among them, the 115 clones had the strongest drought resistance, Woodland promotion.
