| 摘 要： | 为了提高徐州市石灰岩山地侧柏人工林的生态和景观质量,采用分层切割法对云龙山侧柏人工林的生物量进行研究.结果表明:(1)林分密度较低、立地条件较好的侧柏林各器官生物量的排列顺序为:树干＞树根＞树枝＞树叶;林分密度较高、立地条件较差的侧柏林各器官生物量的排列顺序为:树干＞树枝＞树根＞树叶;(2)林分密度较低、立地条件较好的侧柏林的生产力以及单位面积生物量、单株生物量都大于林分密度较高、立地条件较差的侧柏林;(3)建议通过间伐、抚育、土壤改良等措施,调整林分结构,提高侧柏林的营养条件.这为今后侧柏人工林的综合经营与管理提供了一定的科学依据.

| Abstract: | In order to improve the quality of ecology and landscape of Platyclatdus orientalis plantation in limestone mountain areas in Xuzhou,we studied the biomass of Platyclatdus orientalis plantation by "divided-storeys" method in Yunlong Mountain. The results showed that the biomass of Platyclatdus orientalis in the lower density stands with the better site conditions was in the order of trunk>root>branch>leaf,while in the higher density stands with the poor site conditions it was in the order of trunk>branch>ro... |
