| 摘 要： | 研究了泰山刺槐人工林经不同次数抚育间伐后的林分结构及刺槐的径级分布变化,结果表明:(1)在混交林还是纯林中,保留刺槐的胸径和树高均随间伐次数的增加而减少,表现为抚育间伐0次抚育间伐1次抚育间伐2次抚育间伐3次。(2)混交林的林分密度和刺槐现存密度随采伐次数的增多都有加大的趋势。抚育间伐对刺槐混交林起到定向引导作用。(3)建议营建适当配比的块状混交林以提高森林的生态功能。

| Abstract: | The changes in stand structure and distribution in diameter class of artificial R.pseudoacaciaforest after different thinning times were studied.The results were as follows：（1）in the mixed forest and pure forest of R.pseudoacacia,DBH and tree height of the locust tree retained were increased with times of thinning and reduced,manifested as follow∶Tending thinning 0timesthinning 1timesthinning 2timesthinning 3times.（2）Stand density of the mixed forest and R.pseudoacaciaincreased with the times of thinning.The tending and thinning played a guided role on R.pseudoacacia mixed forest.（3）The construction of proper proportion of bulk mixed forest should be constructed in order to improve the ecological function of forest. |
