摘　　要：目的通过生态适宜性区划研究,为我国南沙参资源可持续利用提供依据。方法通过查阅资料和实地采集,收集南沙参共493个样点信息(包括轮叶沙参263个、沙参230个),综合55个生态因子,应用地理信息系统和最大熵模型分析南沙参的生态适宜性分布。结果影响南沙参生态适宜性的主要环境因子是降水量、温度、坡度、海拔、土壤亚类,其适宜生境主要集中在江苏、安徽、浙江、贵州、湖南、湖北等地。结论本研究结果可为合理选择优质南沙参种植地区提供依据。Objective To provide the basis for sustainable utilization of Adenophorae Radix through study on the ecological suitability distribution of Adenophorae Radix.Methods Through online data search and field collection,493 samples of Adenophorae Radix were collected(including 263 samples of Adenophora tetraphylla(Thunb.)Fisch.,230 samples of Adenophora stricta Miq.).Combining 55 ecological factors,GIS and MaxEnt models were used to analyze the ecological suitability distribution of Adenophorae Radix.Results The main environmental factors influencing the ecological suitability of Adenophorae Radix were precipitation,temperature,slope,elevation,and soil subtype.The most suitable habitats of Adenophorae Radix were mainly concentrated in Jiangsu Province,Anhui Province,Zhejiang Province,Guizhou Province,Hunan Province and Hubei Province.Conclusion The results can provide the basis for choosing the planting area of Adenophorae Radix of high quality reasonably.
