摘　　要：油茶低改工程是我国农业综合开发的一项重要工程，油茶低产林改造效应的研究，为油菜低改工作的顺利开展提供重要的理论依据。本文从低改后的生长效应、结实效应、生态效应方面论述了油茶低改增产机理，分析了效应间的相互关系，并在此基础上，对油茶低改措施组合进行决策分析，结果表明：综合改造效应最显著。ABSTRACT Oiltea camellia，Camellia oleifera,is one of the principal nontimber forestcrops peculiar to China. It is widely grown for its seed from which a good edible oil is ex-tracted．However，production waxnot satisfactory for a long time. Hence an improvernenttrial was conducted from 1990 to 1992，with a view to promoting the seed yield through eco-logically sound horticultural treatments，This paper presents an analysis of benefit in termsof stand growth，seed production，and water and soil conservation，Results so far haveproved that the improvement trial was a great success in all respects.KEY WORDS Oiltea camellia；Stand improvement; Benefit analvsis.
