摘　　要：基于110份金莲花样本分布信息及55个环境生态因子数据,利用Maxent模型预测金莲花生态适宜性分布区,旨在为金莲花引种栽培选址提供理论依据。研究结果显示,Maxent模型预测结果较好(AUC>0.9);7月降水量、温度季节性变化标准差、年均温变化范围、8月降水量及海拔为影响金莲花分布的主要环境因子;金莲花生态适宜性分布区主要集中在山西、河北、内蒙古东部、吉林及辽宁和黑龙江西部、陕西北部、宁夏南部、甘肃东部及南部、青海东部地区。研究结果表明,除金莲花传统的分布区外,陕西北部、宁夏南部、甘肃东部及南部、青海东部地区可作为金莲花引种栽培适生地选择区。该研究结果为金莲花引种栽培适生地选择提供了理论依据。Based on the distribution information of 110 samples and 55 environmental factors,Maxent model was used to predict the ecology suitability regions of Trollius chinensis. The study aims at providing theory basis for the cultivation of T. chinensis. The results showed that the Maxent model prediction result was good( AUC > 0. 9) and the main factors effecting the ecology suitability regions of T. chinensis were precipitation in July,standard deviation of seasonal variation of temperature,annual mean temperature,precipitation in August and altitude. The ecology suitable regions of T. chinensis mainly concentrated in Shanxi,Hebei,east of Inner Mongolia,west of Jilin and Liaoning,north of Shaanxi,south of Ningxia,east and south of Gansu,and east of Qinghai. The results indicated that except for traditional distribution regions,north of Shaanxi,south of Ningxia,east and south of Gansu,and east of Qinghai could selected as the regions for cultivation of T. chinensis. It provides theory basis for selecting suitable regions to cultivate T. chinensis.
