| 摘 要： | 目的探究变叶海棠及其同域近缘种潜在地理分布及生境特征。方法基于全国尺度下的气候、土壤、地形和植被类型等生态因子插值数据,结合变叶海棠、花叶海棠和陇东海棠地理分布信息,利用MaxEnt模型和ArcGIS软件的空间分析功能,分析了变叶海棠、花叶海棠和陇东海棠潜在地理分布及其生境特征。结果变叶海棠、花叶海棠和陇东海棠呈地理替代分布,变叶海棠主要分布于中国—喜马拉雅森林植物亚区,花叶海棠主要分布于亚洲荒漠植物亚区,陇东海棠分布区属中国—日本森林植物亚区;海拔可能是造成花叶海棠、变叶海棠和陇东海棠资源分布区域差异性的主导生态因子。结论本研究成果可为变叶海棠、花叶海棠和陇东海棠资源保护利用和人工栽培提供参考。

| Abstract: | Objective To explore the potential geographical distribution and habitat characteristics of Malus toringoides(Rehd.)Hughes and its sympatric related species.Methods Based on the scale of the country's ecological factors such as climate,soil,terrain and vegetation types,combing with their distribution information of Malus toringoides(Rehd.)Hughes,Malus transitoria(Batal.)Schneid.and Malus kansuensis(Batal.)Schneid.to study their potential distribution and habitat characteristics by using MaxEnt and ArcGIS model.Results The results show that their potential geographical distribution presents alternative distribution phenomenon,thegrowth area of Malus toringoides(Rehd.)Hughes China-Himalaya forest plant sub-region,and Malus transitoria(Batal.)Schneid mainly concentrate inAsian Desert Plant Sub-region,where China-Japan Forest Plant sub-zone is the mainly distribution area of Malus kansuensis(Batal.)Schneid.Habitat altitude may be the dominant ecological factors that causing the difference in their distribution.Conclusion The results of this study can provide reference for resource protection,utilization and artificial cultivation of Malus toringoides(Rehd.)Hughes,Malus transitoria(Batal.)Schneid and Malus kansuensis(Batal.)Schneid. |
