摘　　要：目的对党参生态适宜性进行分析,为扩大山西省党参种植规模提供理论参考。方法通过山西省第四次中药资源普查数据和查阅文献等途径获得党参样点分布信息,应用最大熵(MaxEnt)模型和地理信息系统软件ArcGIS10.8分析影响山西省党参分布的生态因子,预测党参在山西省适宜性分布区域。结果模型预测的山西省党参分布区域与实际分布区域吻合度较高;训练集AUC=0.945,预测结果较好。影响党参分布的主要环境因子贡献率是植被类型(31.1%)、温度季节性变化标准差(25.0%)、坡度(8.3%)、1月份平均降水量(5.3%)、5月份平均降水量(5.0%)、高程(4.9%)等。最适宜党参分布的植被类型为温带落叶灌丛、温带草丛、温带针叶林、温带落叶阔叶林,温度季节性变化标准差为92~108,坡度为14°~30°,1月份平均降水量为4~6.8 mm,5月份平均降水量为33.5~58 mm,高程为1100~2800 m。党参在山西省适宜区主要分布在太岳山东部的长治市潞城区、沁县、沁源县,吕梁山脉一带的临汾市蒲县、汾西县,吕梁市汾阳市和太岳山北部的晋中市榆社县。山西省最适宜区面积为14109.67 km^(2),适宜区面积为22837.62 km^(2),较适宜区面积为41982.96 km^(2),不适宜区面积为77769.75 km^(2)。结论根据山西省党参资源的地理分布情况进一步检验区域划分的结果,可在山西省各山脉如太行山脉等附近建立党参野生栽培基地,同时根据党参适宜生长环境条件调整人工栽培条件,优化党参资源。Objective To analyze the ecological suitability of Codonopsis pilosula;To provide theoretical reference for expanding the planting scale of Codonopsis pilosula in Shanxi Province.Methods Information on the distribution of Codonopsis pilosula samples through the fourth survey of TCM resources in Shanxi Province and literature review;the MaxEnt model and ArcGIS 10.8 geographic information system software were used to analyze the ecological factors affecting the distribution of Codonopsis Radix in Shanxi Province,and the suitable distribution areas of Codonopsis pilosula in Shanxi Province were predicted.Results The predicted distribution areas of Codonopsis pilosula in Shanxi Province by the model were highly consistent with the actual distribution area;the AUC of the training set was 0.945,indicating good prediction results.The predominant ecological factors(contributing)impacting the distribution of Codonopsis pilosula included vegetation type(31.1%),the standard deviation of seasonal temperature fluctuations(25.0%),slope(8.3%),mean January precipitation(5.3%),mean May precipitation(5.0%),and elevation(4.9%)etc.The optimal vegetation types conducive to the proliferation of Codonopsis pilosula were identified as temperate deciduous shrubs,temperate grasslands,temperate coniferous forests,and temperate deciduous broad-leaved forests.The standard deviation of seasonal temperature change was within the range of 92 to 108,the slope gradient was from 14°to 30°,mean January precipitation was of 4 to 6.8 mm,mean May precipitation was of 33.5 to 58 mm,and elevation ranged from 1100 to 2800 meters.Codonopsis pilosula was mainly distributed in Lucheng,Qinxian and Qinyuan counties in the eastern part of Taiyue Mountain in Changzhi City;Pu County,Fenxi County,Fenyang City of Lyuliang City in the Lyuliang Mountain Range and Yushe County of Jinzhong City in the northern part of Taiyue Mountain.The most suitable area in Shanxi Province was 14109.67 km^(2),the suitable area encompassed 22837.62 km^(2),the relatively suitable ar
