摘 要:根据Delphi法,从生态适应性、抗逆性、生态效益、观赏价值等方面确定了南京城市生态绿化树种评价的3级指标;采用层次分析法(AH,P)测算指标权重,并首次采用熵技术对权系数进行修正,从而得到南京城市生态绿化树种选择的综合评价模型;对南京城市森林常见的600余种乡土及园林绿化木本植物进行综合计算与评价,划分出Ⅲ级以上绿化生态树种共350种,其中Ⅰ级树种40种,Ⅱ级树种148种,Ⅲ级树种162种,为南京绿化生态树种的科学选择提供了一定的参考依据。An evaluation index system for urban afforestation species in Nanjing City was established in terms of eco-adaptation,resistance,ecological benefit,and ornamental value according to the Delphi method.The importance weights were calculated by the analytic hierarchy process (AHP),and the weight coefficients were modified by the entropy technology.More than 600 native tree species and afforestation tree species were evaluated according to the index system.A total of 350 tree species were selected as the superior afforestation tree species,of which 40 species were ranked as the first grade,148 species as the second grade,and 162 species as the third grade.
