摘要
开展黄芩属(Scutellaria)药用植物现有资源生态适宜性区划能为其生态适宜性范围预测及栽培区域的选择提供科学依据。本研究收集了山西省3种分布较多的黄芩属药用植物样点分布信息(其中黄芩(Scutellaria baicalensis Georgi)421个、并头黄芩(S.scordifolia Fisch.ex Schrank)87个、粘毛黄芩(S.viscidula Bunge.)14个),结合55个生态因子数据,应用最大熵模型(MaxEnt)和地理信息系统(ArcGIS)分析影响3种黄芩属药用植物适生区分布的关键生态因子。结果表明:影响3种黄芩属药用植物适生区分布的关键生态因子主要有植被类型、海拔、降水量等,不同物种间影响其生态适宜性的关键生态因子差异显著;黄芩和并头黄芩在山西省的适生区分布较广,忻州、吕梁、临汾、长治、晋中、太原、朔州等地均有较大面积的适宜分布区;粘毛黄芩在山西的适生区分布较少,主要集中在山西省北部大同、朔州、忻州等地。研究结果对于山西省黄芩及其代替品并头黄芩和粘毛黄芩的合理引种栽培和黄芩的规范化生产具有参考和指导性意义。
Studies on the ecological suitability zoning of Scutellaria medicinal plants can provide scientific data for predicting the ecological suitability range and selecting suitable cultivation areas of medicinal plants in Scutellaria.We collected the distribution information of three widely distributed medicinal species of Scutellaria in Shanxi Province during the Fourth National Survey of Traditional Chinese Medicine Resources(including 421 samples of Scutellaria baicalensis Georgi,87 samples of S.scordifolia Fisch.ex Schrank,and 14 samples of S.viscidula Bunge.),as well as data of 55 ecological factors.The Maximum Entropy Model(MaxEnt)and Geographic Information System(ArcGIS)were used to identify the key ecological factors affecting the distribution of suitable habitats for three Scutellaria species.The results showed that vegetation type,altitude,precipitation were the main factors affecting the distribution of suitable habitats for the three Scutellaria species.The critical factors affecting the ecological suitability varied among species.S.baicalensis and S.scordifolia had a wide distribution of potential suitable areas in Shanxi Province,with relatively large suitable distribution area in Xinzhou,Lvliang,Linfen,Changzhi,Jinzhong,Taiyuan,and Shuozhou.The potential distribution of S.viscidula in Shanxi Province was relatively small,mainly concentrated in Datong,Shuozhou,and Xinzhou(the northern regions of Shanxi Province).Our results provide references for the rational introduction and cultivation of S.baicalensis and its substitutes(S.scordifolia and S.viscidula),and will facilitate the standardized production of S.baicalensis in Shanxi Province.
