摘　　要：闽南沿海山地混交林种间关系的演变过程 ,大体可以划分为相对稳定时期、竞争初期、竞争盛期和竞争后期等 4个不同的阶段。相对稳定期主要采取幼林抚育方法 ,而以局部松土除草为宜 ;竞争初期主要采取块状透光伐 ,伐除强度约为30 % ;竞争盛期则采用疏伐的方法 。The evolution courses of interspecific relations of mixed forests on coastal hilly lands of South Fujian may be divided into 4 various periods of relative stable stage,competitive initial,hot and later stages.The young forest tending method is majorly adopted at the relative stable stage,whereas it is proper to loosen the soils and weed locally;patch lighting of trees is mainly adopted at the competitive initial stage,intensity of cut is about 30%,thinning method is used to adjust interspecific relations at the competitive hot stage.
