摘　　要：首次应用标准差选择法、多目标决策和集对分析原理对红豆树人工林进行优树选择.选择红豆树优树22株,与全省红豆树胸径、树高、材积年平均生长量相比,分别增长了95.7%、29.5%、400.6%.精选优树8株,胸径、树高、单株材积年平均生长量分别为:1.23 cm、0.6 m、0.0497 m3,与全省红豆树平均生长量相比,分别增长了125%、36.4%、664.6%;与优树均值相比分别增长15%、5.3%、36.5%.The standard deviation method, multi-objective decision method, and set pair principle were applied in the elite tree se- lection for the plantation forest of Ormosia hosiei. 22 predicted individuals were selected. Their average annum increment in DBH, height and individual volume were 95.7%, 29.5%, 400.6%, respectively, compared to Ormosia hosiei in Fujian with annum growth, respectively. 8 of them were further selected, and their average annual growth in DBH, height and individual volume were 1.23 cm, 0.6 m and 0.0497 m3, respectively,r Their average annual increment in DBH, height and volume were 125%, 36.4% and 664.6%, respectively, compared to average growth of Ormosia hosiei in Fujian; and the increment 15%, 5.5% and 36.5%, re- spectively, compared to the growth of predicted elite tree of Ormosia hosiei.
