摘　　要：目的探究影响金银花生长的环境因子,预测当前和未来气候条件下金银花在我国的生态适宜性分布。方法收集2553条金银花样点分布信息和19个环境因子数据,运用最大熵(MaxEnt)模型筛选影响金银花生长的主要环境因子,结合地理信息系统软件ArcGIS10.8模拟当前和未来气候条件下金银花在我国的适生区。结果影响金银花分布的主要环境因子是最冷月份最低温度、平均气温日较差、最湿季度降水量和气温年较差。当前气候条件下金银花在我国适生面积约为318.29×10^(4)km^(2),主要分布在华中和华南地区。在未来气候情景下,金银花总适生区面积将有所下降。结论本研究预测的金银花资源分布和生态适宜区可为其野生抚育、合理栽培及资源保护提供理论依据。Objective To explore the environmental factors affecting the growth of Lonicera japonica Thunb.;To predict the suitable areas of L.japonica in China under current and future climate conditions.Methods Totally 2553 pieces of L.japonica distribution information and 19 environmental factors were collected.MaxEnt model was used to screen the main environmental factors affecting the growth of L.japonica.Combined with ArcGIS 10.8 software,this article simulated the suitable area of L.japonica in our country under current and future climate conditions.Results The main environmental factors affecting the distribution of L.japonica were the lowest temperature in the coldest month,the average daily temperature range,the precipitation in the wettest quarter and the annual temperature range.Under the current climate conditions,the suitable area of L.japonica in China was about 318.29×10^(4) km^(2),which was mainly distributed in central and southern China.Under the future climate scenario,the total suitable area would decrease.Conclusion This study predicted distribution of L.japonica resources and ecological suitability areas can provide theoretical basis for its wild cultivation,rational cultivation,and resource protection.
