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。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 〉 root 〉 leaf. The productivity, individual biomass and hiomass per hectare in the lower density stands with better site conditions was greater than that in the higher density stands with the poor site conditions respectively. The measures of thinning and soil improvement should be taken in order to improve nutritional conditions of Platyclatdus orientalis and to increase the productivity of Platyclatdus orientalis stands.
