摘　　要：以淮北平原地区发展林下经济,选取林-药模式作为分析对象,讨论在同一树种不同的郁闭度林分中对板蓝根生理生态因子的影响。结果表明在中郁闭度林分中,板蓝根的生理生态因子比疏林地和密郁闭度林分中表现稳定;中郁闭度林分与疏林地比密郁闭度林分,对板蓝根的生理生态因子都产生明显的影响。为合理选择种植板蓝根的林分提供了一定的实践指导意义。This paper selects the forest-medicine model as the analysis object based on the devel-opment of under-forest economy in Huaibei Plain area,and discusses the influence of different canopy closure stands of the same tree species on the physiological and ecological factors of Radix Isatidis.The results show that the physiological and ecological factors of Radix Isatidis are more stable in the medium canopy closure stand than those in the sparse forest and dense canopy closure stands.Compared with the dense canopy closure stands,the medium canopy closure stands and sparse forest have a significant im-pact on the physiological and ecological factors of Radix Isatidis.This provides some practical guidance for the rational selection of Radix Isatidis planting stands.
