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 ,调整种间关系 The evolutionary process of interspecific relationships in southern Fujian coastal mountainous areas can be divided into four stages: relatively stable period, early stage of competition, peak period of competition and late stage of competition. The relatively stable period mainly took the young forest tending method, but the local loosening and weeding was appropriate. In the early stage of competition, the block-like translucent cutting was adopted and the cutting strength was about 30%. During the competition, thinning was used to adjust interspecific relationships
