| 摘 要： | 应用典型调查与定位试验相结合的方法,探讨了黑松海防林低质低效的形成原因,据其成因将这些林分划分为5种类型,提出了相应的改造意见,并编制出黑松海防林密度管理表。通过更新造林和抚育技术试验,提出了较合理的更新方式,主要有林冠下更新造林、留伐桩萌芽更新、隔行更新造林、人工促进天然更新、带状更新等,其中,带状更新适于在林分条件相对较好的情况下应用,其它几种更新方式较适于低效林的更新改造;采用稀疏林补植、林下种植灌木或绿肥压青、封禁保护枯落物等技术,可有效地改善林分状况。 |

| Abstract: | Apply typical inventory and fixed site experiment to study their formation factors of loweryield,lower-quality,lower-effective coastal protection forest of Pinus thunbergii,according to this.We divieled those forest into 5 types,to put forward their regeneration and tronsformation purposes respectively,and to edit density-controled table of Pinus thunbergii pratection forest.Applying the experiment with regeneration affarestation and foster techniques,We put forward reasonakk regeneration madels.Main models amany them:regeneration afforestation under crown cover,sprout regeneration by cutting stake,regeneration afforestation bg intermission,artifical stimulating natural regeneration,regeneration by belt.The regeneration by belt among them fits forest in which is growing condition better,the others suitable for lower-yield forest.Applied the techniques of additional afforestation in few and scattered forest,planted shrub under crown cover on buried green plant as fertilizar,preserved withered and dead things with blackade,forest growing situation are effectively improved. |
