为探索低质低效次生林经营改造技术，以广东省古兜山南亚热带次生林为研究对象，通过树种引入套种更新试验，进行优良树种的选择评估。研究以生长适应性、经济效益、生态功能和景观功能为树种选择的主要依据，确定了13项定性和定量分级指标，采用4分制建立各项指标的分级标准，运用层次分析法，构建了南亚热带次生林引入套种树种的评价指标体系，对试验林中7．5 a生的引入套种树种的综合表现进行分析与评价。结果表明，69个引入套种树种的综合评价值分布在1．74～3．08之间，树种间综合表现差异明显，壳斗科、樟科、金缕梅科等本地植物区系优势科的树种表现较好。在树种综合表现值的基础上，根据树高、胸径的年均生长量将套种树种分为速生型、中等速生型和慢生型3个类型，评选出综合表现值在2．5以上的优良树种37个，其中速生型树种7个、中等速生型树种17个、慢生型树种13个，为南亚热带次生林引入套种以及人工促进更新树种的合理选配提供参考。
為探索低質低效次生林經營改造技術，以廣東省古兜山南亞熱帶次生林為研究對象，通過樹種引入套種更新試驗，進行優良樹種的選擇評估。研究以生長適應性、經濟效益、生態功能和景觀功能為樹種選擇的主要依據，確定瞭13項定性和定量分級指標，採用4分製建立各項指標的分級標準，運用層次分析法，構建瞭南亞熱帶次生林引入套種樹種的評價指標體繫，對試驗林中7．5 a生的引入套種樹種的綜閤錶現進行分析與評價。結果錶明，69箇引入套種樹種的綜閤評價值分佈在1．74～3．08之間，樹種間綜閤錶現差異明顯，殼鬥科、樟科、金縷梅科等本地植物區繫優勢科的樹種錶現較好。在樹種綜閤錶現值的基礎上，根據樹高、胸徑的年均生長量將套種樹種分為速生型、中等速生型和慢生型3箇類型，評選齣綜閤錶現值在2．5以上的優良樹種37箇，其中速生型樹種7箇、中等速生型樹種17箇、慢生型樹種13箇，為南亞熱帶次生林引入套種以及人工促進更新樹種的閤理選配提供參攷。

Studies on the selection of tree species for the south subtropical forests regeneration by interplan-ting was carried out in Gudou Mountain in Guangdong.A tree species evaluation system was established in which growth adaptability,economic value,ecological function and landscaping benefit were key issues.Thirteen traits/indices of trees were integrated into the system as suitability indicators and a four-grade system was established for quantitatively evaluating indicators.Analytic hierarchy process (AHP)was adopted to determine the weights of each index.According to the score and weight of each index,69 kinds of introduced tree species were integrative e-valuated with the investigation and information search when the regeneration stand was 7.5 years old.The result showed that the composite evaluating value,according which 69 tree species were classed into three growth types, was between 1.74 to 3.08.There were obvious differences of the comprehensive performance among the tree spe-cies.The tree species of Fagaceae,Lauraceae and Hamamelidaceae displayed remarkable suitability in the stand. It was suggested that 37 tree species with a composite evaluating value >2.5 were selected as the adaptive species for the south subtropical forests regeneration by interplanting,including 7 species of fast-growing type,17 species of secondary fast-growing types and 13 species of slow-growing type.
