摘  要:为选育三峡库区漆树(Toxicodendronw acifluum)优良树木,于2015年在重庆市城口、开县、奉节、巫溪、巫山等区县对100株漆树的立地条件、生长状况、果实等情况开展调查.研究共设置26个调查指标,设定2种情景:各指标权重相等(情景1)、各指标权重不等(情景2).在情景2中,根据26个评价指标,采用层次分析法(AHP)构建以目标层、项目层、指标层为3个层次的漆树优选评价指标体系,根据两两比较法设置26个指标的相对权重.分别计算2种情景下100株漆树的综合评价指数,根据综合评价指数大小进一步筛选优良漆树.结果发现,2种情况下100株漆树综合评价指数差异无统计学意义.依据筛选目标,最终选取在情景2中排名靠前的60株漆树作为所筛选出的三峡库区优质漆树.其中,城口14株,奉节19株,巫山11株,巫溪16株.In order to select superior lacquer(Toxicodendronw acifluum)trees in the Three Gorges Reservoir Area,site conditions,growth conditions and fruits of 100 lacquer trees from Chengkou,Kaixian,Fengjie,Wuxi,and Wushan of Chongqing municipality were investigated.We established an index framework involving 26 indexes for superior lacquer tree selection and studied 2scenarios,i.e.Scenario 1,in which each index shared the same weight,and Scenario 2,in which each index had different weights.The relative weights of the 26 indexes were established with the paired comparison method,and the comprehensive evaluation value for each tree under the two scenarios was calculated by summing up the products of standard value of each index and their weights.In Scenario 2,the weights for each index were provided through the analytic hierarchy process(AHP).Superior lacquer trees were selected after ranking the comprehensive evaluation values.The results showed that there was no significant difference between the comprehensive evaluation values under the two scenarios.According to the final goal,60 superior lacquer trees were selected from Scenario 2,of which 14,19,11 and 16were from Chengkou,Fengjie,Wushan,and Wuxi,respectively.
