Research on the Suitable Growth Areas of Peucedanum praeruptorum and Ecological Factors Affecting Quality
摘要
Abstract
Objective:To understand the suitable growth areas of Peucedanum praeruptorum in China,to master the ecological fac-tors affecting the accumulation of coumarin components in Peucedanum praeruptorum,so as to provide a reference basis for the protec-tion,development and utilization of medicinal resources of Peucedanum praeruptorum.Methods:Ecological suitability prediction and a-nalysis were conducted using MaxEnt software.Field investigations were carried out in the production areas and samples were collected.The coumarin index components of samples from different production areas were compared.The correlation between the quality of medic-inal materials and the environmental factors of suitable growth areas was analyzed.The dominant ecological factors affecting the distribu-tion of Peucedanum praeruptorum and the quality of medicinal materials were screened out.Result:The AUC value of the MaxEnt model training set samples was 0.962,and the AUC value of the test set samples was 0.919.The suitable habitats for Peucedanum praerupto-rum in China were mainly concentrated in Guizhou,western Hunan,western Hubei,southern Shanxi,eastern Chongqing,central and western Zhejiang,southwestern Anhui,northwestern Jiangxi,etc.The comprehensive quality evaluation results of medicinal materials showed that the quality of Peucedanum praeruptorum medicinal materials in Yunnan,Hubei,Guizhou,Zhejiang and other places were ex-cellent.The most important ecological factors affecting the distribution of Peucedanum praeruptorum and the contents of coumarin com-ponents were the precipitation in the driest month and the lowest temperature in the coldest month.Conclusion:The suitable growth areas predicted by the MaxEnt model and the ArcGIS geographic information system for Peucedanum praeruptorum are accurate and reliable.This study has guiding significance for the introduction and cultivation of Peucedanum praeruptorum and the formulation of scientific management measures for the standardized planting of Peucedanum praeruptorum medicinal materials.关键词
