摘　　要：目的:对全国范围内的野生苍术进行生态适宜性和品质区划,为苍术的栽培选址和优质生产提供科学指导。方法:采用文献搜集的方法收集近30年与苍术分布和挥发油含量相关的研究数据,用最大熵模型(MaxEnt)和地理信息系统(GIS)对野生苍术生态适宜性进行区划,并对苍术的适宜种植区和品质形成区进行预测。结果:1)野生苍术最适宜分布区主要集中在燕山山脉、太行山脉、陕北高原南部、秦岭山脉、伏牛山区、大巴山区、桐柏山区、大别山区、茅山周边及黄山周边地区;2)合格野生苍术(苍术素含量>0.30%)最适宜分布区集中在湖北省中部的大洪山、河南省与湖北省交界处的桐柏山和大别山区、安徽省中部的张八岭和江苏省南部的茅山山区至上海的大部分地区,其中大别山区的野生苍术品质差异较大。结论:MaxEnt和GIS对野生苍术生态适宜性分布区预测结果可靠有效。生态环境因子并不是影响苍术品质形成的唯一决定因素,生产合格苍术药材需要有优良的种质资源,以及合适的生态种植环境,如林下、林缘或田间作物套种等。Objective:To regionalize the ecological suitability and quality of wild Atractylodes lancea in China,so as to guide the selection of cultivation sites and the production of high-quality A.lancea.Methods:The research data on the distribution and volatile oils of A.lancea in the recent 30 years were collected from relevant literature.MaxEnt and the geographic information system(GIS)were employed to regionalize the ecological suitability and quality of wild A.lancea,and then the suitable planting areas and quality formation areas of A.lancea were predicted.Results:1)The suitable distribution areas of wild A.lancea concentrated in Yanshan Mountains,Taihang Mountains,southern loess plateau of northern Shaanxi province,Qinling Mountains,Funiu Mountains,Daba Mountains,Tongbai Mountains,Dabie Mountains,and the areas around Maoshan Mountains and Huangshan Mountains.2)The suitable distribution areas of qualified wild A.lancea(atractylodin content>0.30%)concentrated in Dahong Mountains in the middle of Hubei province,Tongbai Mountains and Dabie Mountains at the junction of Hubei and Henan provinces,Zhangbaling Mountains in the middle of Anhui province,and most areas from Maoshan Mountains in the south of Jiangsu province to Shanghai.In addition,the quality of wild A.lancea in Dabie Mountains varied greatly.Conclusion:MaxEnt and GIS are reliable and effective in predicting the suitable distribution area of wild A.lancea.Ecological and environmental factors are not the only determinants affecting the quality of A.lancea.It is suggested that elite germplasm resources and appropriate ecological planting modes such as intercropping under forest,on forest edge,and with field crops should be selected for the production of high-quality A.lancea.
