| 摘 要： | 针对本地区马尾松林分由于受诸多因素影响而分化严重的现象,为提高马尾松林分的质量,开展马尾松林合理的经营密度研究.试验结果表明,马尾松林分其冠幅与胸径生长呈显著正相关,运用冠幅与胸径的相关规律,推算马尾松林不同生长发育阶段适宜的密度指标,并以此指导适时进行抚育间伐,调整林分密度,改善林分生境条件,促进林木生长.

| Abstract: | In order to improve Pinus massoniana forest stand quality,the stand density experiment of Pinus massoniana forest was conducted in Shan-ming,Fujian Province.The results showed that the tree-crown and diameter in breast highet(DBH)of Pinus massoniana forest existed positive relation significantly.Based on this relationship the reasonable stand density indexes were estimated for the different age stands of Pinus massoniana forest.These results would be very useful for selective cutting,adjusting forest density,and hence improving tree growth. |
