摘　　要：目的基于最大熵(MaxEnt)模型和地理信息系统软件ArcGIS筛选影响夏枯草生长的主要环境因子,预测其在中国的潜在适生区,为夏枯草人工栽培提供参考。方法收集346条夏枯草样点数据,结合38个环境因子数据,利用MaxEnt模型筛选影响夏枯草分布的主要环境因子,利用ArcGIS软件对夏枯草生境适宜性进行评估,分析全球和中国夏枯草适生区分布。结果影响夏枯草分布的主要环境因子为上层(0~30 cm)碎石体积百分比、土壤有效水含量、上层(0~30 cm)可交换钠盐、土壤单元中与农业用途有关的特定土壤类型、上层(0~30 cm)沙含量。夏枯草高适生区主要分布在云南、黑龙江、内蒙古东部、四川中部。结论本研究预测结果可为夏枯草引种栽培及资源可持续利用提供参考。Objective To screen the main environmental factors affecting the growth of Prunella vulgaris L.based on MaxEnt model and ArcGIS;To predict its potential suitable habitats in China;To provide reference for the artificial cultivation of Prunella vulgaris L.Methods Totally 346 pieces of sample point data of Prunella vulgaris L.were collected.Combined with data of 38 ecological factors,the main environmental factors affecting the distribution of Prunella vulgaris L.were screened using MaxEnt model.ArcGIS software was used to evaluate the habitat suitability of Prunella vulgaris L.and analyze the distribution of suitable areas for Prunella vulgaris L.worldwide and in China.Results The main ecological factors affecting the distribution of Prunella vulgaris L.were upper(0-30 cm)soil gravel volume percentage,soil effective water content,upper(0-30 cm)soil exchangeable sodium salt,specific soil types related to agricultural use in soil units and upper(0-30 cm)soil sand content.The highly suitable areas of Prunella vulgaris L.were mainly in Yunnan,Heilongjiang,eastern Inner Mongolia and central Sichuan.Conclusion The predicted results can provide a reference for the introduction of cultivation and sustainable resource utilization of Prunella vulgaris L.
