摘要
根据不同立地条件和不同类型基干林带黑松防护林更新试验结果 ,认为林冠下更新造林、留伐桩萌芽更新、隔行更新造林、人工促进天然更新以及带状 (或块状 )更新造林等方式适宜沿海基干林带黑松防护林更新改造。在基干林带前沿 ,立地条件较差 ,防护要求较高 ,宜采用林冠下更新、隔行更新和留伐桩更新等方式。在基干林带后沿 ,立地条件较好 ,防护要求相对较低的防护林 ,宜采用带状更新 ,更新带宽以 30m左右为宜 ,最大不能超过 6 0m。对于林下天然更新效果较好的成、过熟林带 ,可人工促进天然更新。
According to the experiment results of Pinus thunbergii forest in different kinds of backbone forest belts and sites, the methods suited to the regeneration of Pinus thunbergii forest in backbone forest belt were put forward such as regeneration under crown canopy, sprouting regeneration on stock, regeneration in alternate lines, natural regeneration with artificial aid, regeneration in strip or block, and et al. Regeneration under crown canopy, sprouting regeneration on stock, regeneration in alternate lines are fit for the forward of core forest belt requiring good protection, where site is in poor condition. Regeneration in strip is suitable for the backward of core forest belt requiring comparatively secondary protection, where site is in good condition, the appropriate width is about 30 m, not exceeding 60 m in maximum. Natural regeneration with artificial aid is appropriate for mature forest and over-mature forest, where natural regeneration under forest has good effect.
