摘　　要：目的:探索苗族药红禾麻潜在适宜分布区及其优质药材产区空间分布状况。方法:基于200个红禾麻分布位点及120个生态因子,利用最大熵模型(MaxEnt)及地理信息系统(ArcGIS)软件预测其潜在适生区。采用高效液相色谱法(HPLC)测定33批黔产红禾麻中芦丁、山柰酚-3-O-芸香糖苷、槲皮苷的含量,结合前期所测药材总多糖、总黄酮的含量数据,分析红禾麻主要药效成分与生态因子的相关性,并借助ArcGIS中协同克里金插值法进行品质区划。结果:红禾麻在我国最适分布区为云南、贵州、四川、湖南及湖北等地,其高、中适生区面积占总分布面积的59.48%。影响红禾麻生长分布的主要生态因子为10月降水量、坡度、冷季最低温、海拔、6月太阳辐射强度及4月降水量;温度、辐射强度、降水量、土壤组分及性质等对红禾麻次生代谢产物的积累影响较大。红禾麻药材品质研究结果表明,其高品质区主要包括贵州省雷山县、凯里市、清镇市、平坝县、惠水县、龙里县、开阳县及江口县等地。结论:红禾麻在国内分布区域广,但适宜分布区主要集中在西南部及华中部分地区,贵州境内红禾麻种植基地可优选黔东南及黔中地区的部分县市。该研究对红禾麻潜在适生区及其在贵州的最佳种植区进行了预测,可为红禾麻引种栽培及规模化种植选址提供科学参考。Objective:To explore the potential suitable distribution area and spatial production area of high-quality medicinal materials of Miao medicine Laportea bulbifera.Method:Based on 200 distribution spots of L.bulbifera and 120 ecological factors,the maximum entropy model(MaxEnt)and ArcGIS software were applied to predict the potential suitable areas.The content of rutin,kaempferol-3-O-rutinoside,and quercitrin from 33 batches of L.bulbifera in Guizhou province was determined by high-performance liquid chromatography(HPLC).Combined with the previous content data of total polysaccharides and total flavonoids,the correlation between the main pharmacodynamic components of L.bulbifera and ecological factors was analyzed.Eventually,the quality regionalization of L.bulbifera was exhibited by the collocated Cokriging in ArcGIS.Result:The optimum distribution areas of L.bulbifera were Yunnan,Guizhou,Sichuan,Hunan,and Hubei provinces in China,and the high and medium suitable areas accounted for 59.48%of the total distribution areas.October precipitation,slope,min temperature of the coldest month,altitude,solar radiation intensity in June,and April precipitation were the main ecological factors affecting the growth and distribution of L.bulbifera.Temperature,radiation intensity,precipitation,and soil composition and properties had great effects on the accumulation of secondary metabolites in L.bulbifera.The results showed that the high-quality areas of L.bulbifera mainly included Leishan county,Kaili city,Qingzhen city,Pingba district,Huishui county,Longli county,Kaiyang county,and Jiangkou county in Guizhou province.Conclusion:L.bulbifera is widely distributed in China,but the suitable distribution areas are mainly concentrated in southwest China and part of central China.The planting bases of L.bulbifera can be selected in parts of cities and counties in southeast and central Guizhou province.In this study,the potential suitable growing areas and the optimum planting areas of L.bulbifera in Guizhou were predicted,which could
