Study on the Correlation Between Canopy Density and Physiological and Ecological Factors of Isatis Indigotica in the Forest of Huaibei Plain
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.
