摘　　要：采用资料查阅、访问和实地调查相结合的方法,对重庆市山矾科树种资源进行调查。运用层次分析法建立了山矾科树种评价体系,确定了评价因子及其权重,对山矾科树种进行客观定量评价。结果表明,重庆市山矾科树种有15种,其中小乔木9种,乔木6种,主要分布于南川、奉节、主城区等区县,分别占重庆市山矾科树种总数的80%、46.7%和40.0%;四川山矾、棱角山矾和黄牛奶树适应性强、生态效益好、观赏价值高,在城市森林建设中应大力推广应用。This paper studied on tree species resources of Symplocaceae in Chongqing through field survey methods combining with literature review and visit, and then established tree species resources of Symplocaceae evaluation system by using method of Analytical Hierarchy Process （AHP） , confirmed evaluation factors and their weights to evaluate tree species resources of Symplocaceae objectively and quantificationally. The results showed that there were 15 species of Symplocaceae in Chongqing, including 9 species of small trees and 6 species of trees, which mainly distributed in Nanchuan, Fengjie and urban district, accounted for 80% , 46.7% and 40% of Symplocos tree species number in Chongqing respectively. S. setchuensis , S. tetragona , Chenet. Y. and S. laurina should be energetically applied in urban forest construction for they have strong adaptability, good ecological benefits and high ornamental value.
