摘　　要：目的:研究淫羊藿的分布区划。方法:通过实地标本采集并结合中国数字标本馆(CVH)标本信息收集淫羊藿在全国的分布位点,利用地理信息系统(GIS)技术和最大熵模型(MaxEnt)分析其分布格局的主要生态因子。结果:调查发现由于利益驱动无序滥采滥挖致使淫羊藿野生资源趋于枯竭,区划研究表明4月份降水量和高程等24项因子是影响淫羊藿分布的主要生态因子。淫羊藿的潜在分布区主要集中在甘肃省东南部、陕西省南部、山西南部及河南西部等区域并呈带状分布。结论:本研究对淫羊藿原产地资源保护和野生抚育具有指导作用,可为淫羊藿人工繁育用地的合理布局提供科学依据。Objective:To stuoly the current status of Epimedium resources.Methods:The distribution sites of Epimedium in China was collected by on the spot specimens and combined with the Chinese Digital Herbarium(CVH)specimen information.The main ecological factors of the distribution pattern were analyzed by GIS technology and MaxEnt.Results:The investigation found that the wild resources of Epimedium tend to be exhausted due to the disorderly exploitation and overexploitation driven by interests.The zoning study showed that 24 factors such as precipitation and elevation in April were the main ecological factors affecting the distribution of Epimedium.The potential distribution areas of Epimedium are mainly distributed in the southeastern part of Gansu province,southern of Shanxi province,southwestern of Shanxi province and western of Henan province.Conclusion:This study has a guiding effect on the protection of wild aphid origin and wild nursery,and can provide a scientific basis for the rational layout of artificial breeding land of Epimedium.
