摘 要:通过林分调查与相关实验,分析了徐州市侧柏林的林分现状,指出了侧柏纯林存在林分结构不合理、物种多样性极低、树木生长缓慢、森林生物量较小、土壤理化性质不利于植物生长、林分结构亟待改造等主要问题。提出了通过抚育间伐、补植树种、开设林窗和加强管理等经营措施来调整现有林分结构的途径。Forest surveys and related experiments were used to examine the status quo of vegetation and soil in Platycladus orientalis plantation in Xuzhou.The results showed that the forest stand structure was irrational,and species diversity and forest biomass were very low.Soil physical and chemical characteristics were not conducive to plant growth and other major issues,suggesting that the stand structure needed urgent transformation.We suggested that thinning,replanting trees,opening gaps and strengthening the management measures could be applied to adjust the existing stand structure.
