摘　　要：目的:探索小花清风藤潜在适宜分布区及其优质药材产区空间分布状况。方法:结合小花清风藤分布信息及环境因子,运用最大熵(MaxEnt)生态位模型及地理信息系统软件(ArcGIS),预测小花清风藤的潜在适宜分布区。基于环境因子与小花清风藤中总皂苷,总黄酮,槲皮素-3-O-龙胆双糖苷,camellianoside,tsubakioside A,山柰酚-3-O-芸香糖苷,异鼠李素-3-O-芸香糖苷的相关性,借助ArcGIS软件空间插值及模糊叠加功能,对小花清风藤进行品质区划。结果:小花清风藤在我国主要分布于云南、贵州、广西等省区,中、高适生区面积约占全国面积的2.88%。10月,11月降水量,最暖、最干季降水量,温度季节性变化的标准差及海拔是影响小花清风藤适宜性的主要环境因子。坡度、降水量、辐射强度及温度变化等对小花清风藤次生代谢产物的积累具有较大影响。综合潜在适宜分布区及各成分空间插值结果,小花清风藤高品质区主要集中于贵州省西南部,以晴隆县、关岭县、镇宁县、普安县、兴仁县等地区为核心。结论:该研究为小花清风藤的人工栽培选址及药材收购等提供了一定科学指导。Objective:To explore the potential suitable distribution area and the high-quality distribution area of Sabia parviflora.Method:Combined with the distribution information and environmental factors,the maximum entropy(MaxEnt)model and ArcGIS software were used to predict the potential suitable distribution area of S.parviflora.Based on the correlation between environmental factors and total saponins,total flavonoids,quercetin-3-O-gentiobioside,camellianoside,tsubakioside A,kaempferol-3-O-rutinoside and isobariclisin-3-O-rutinoside,the quality regionalization was conducted by using spatial interpolation method and fuzzy superposition function in ArcGIS software.Result:S.parviflora is mainly distributed in Yunnan,Guizhou,Guangxi province in China.The medium and high suitable areas accounts for about 2.88%of the national area.The precipitation in October and November,the precipitation in the warmest and driest seasons,the standard deviation of seasonal changes in temperature and altitude are the main environmental factors that affect the distribution of S.parviflora.Slope,precipitation,solar radiation and temperature change had great influence on the accumulation of secondary metabolites.Based on the results of potential suitable distribution and spatial interpolation of each component,the high-quality areas of S.parviflora are mainly concentrated in the southwest of Guizhou,with Qinglong,Guanling,Zhenning,Pu’an,Xingren county and other areas as the core.Conclusion:This study provides a scientific guidance for the site selection of artificial planting and the procurement of medicinal materials for S.parviflora.
