摘　　要：目的:为了寻找辽宁省林下山参潜在分布区域,分析影响林下山参生态适宜性、品质适宜性的空间分异性的生态因子及其作用关系。方法:选取辽宁省33个栽培基地的林下山参,利用Maxent最大熵模型及ArcGIS进行生态适宜性区划,对7个指标和110个生态因子进行相关性分析,将显著相关的变量(P<0.05)建立偏最小二乘回归分析模型,利用层次分析法进行综合品质区划。利用地理探测器分别对显著影响生境适宜度、品质适宜度的空间分异性的主导生态因子及生态驱动因子之间的交互作用进行分析。结果:植被类型是对辽宁省林下山参适宜区域划分贡献率最高的生态因子。辽宁省林下山参生态适宜区主要位于西丰县至盖州市一线的东北部、东部和东南部。辽宁省林下山参综合品质以宽甸县、桓仁县为中心,分别向西北、西南逐渐递减。在已划定的区域内,林下山参的适生条件和综合品质的积累主要受到以辐射因子为主的辐射因子和降水因子的交互作用的影响。所测样品含量均远高于2020年版《中华人民共和国药典》标准,辽宁省林下山参整体品质较好。结论:根据区划预测结果,凤城市、岫岩县、庄河市、辽阳县、铁岭县、西丰县、盖州市、海城市、大石桥市等区域的部分地区潜在分布面积较大,品质较高,作为潜在栽培区域的可能性极大,仍需进一步实验验证。区划结果可用于为林下山参适生条件和综合品质的积累研究提供思路,可用于为辽宁省林下山参潜在栽培区域的寻找及产业发展提供参考。Objective:To identify potential distribution areas for wild Panax ginseng cultivated under forest in Liaoning province,China,and analyze the ecological factors of spatial stratified heterogeneity affecting its ecological suitability and quality suitability.Method:Wild Panax ginseng samples cultivated under forest were collected from 33 cultivation bases in Liaoning province.The Maxent maximum entropy model and ArcGIS were used to delineate the ecological suitability zones.Correlation analysis was performed on seven indicators and 110 ecological factors.Variables with significant correlation(P<0.05)were used to build partial least squares regression analysis models.A comprehensive quality zoning was conducted using the analytic hierarchy process(AHP).The geographic detector was employed to analyze the interactions among dominant ecological factors of spatial stratified heterogeneity affecting habitat suitability,quality suitability,and the ecological driving factors.Result:Vegetation type was the most influential ecological factor for delineating the ecological suitability zones for wild Panax ginseng in Liaoning province.The main ecological suitability areas for wild Panax ginseng cultivated under forest were located in the northeast,east,and southeast regions along the line from Xifeng County to Gaizhou City.The comprehensive quality suitability of wild Panax ginseng cultivated under forest was highest in Kuandian County and Huanren County and gradually decreased to the northwest and southwest.Within the delineated regions,the suitability conditions and comprehensive quality of wild Panax ginseng cultivated under forest were primarily influenced by the interactions between radiation and precipitation factors.The content of the measured samples was significantly higher than the standards in the 2020 edition of the Chinese Pharmacopoeia,indicating the high overall quality of wild Panax ginseng in Liaoning Province.Conclusion:According to the zoning and prediction results,areas in Fengcheng City,Xiuyan County,Zhuan
