摘 要:淫羊藿(Epimedium brevicornu Maxim.)作为野生药材,品质受到自然环境的影响.为研究淫羊藿品质变化趋势,本研究选取甘肃省南部洮河流域内淫羊藿为研究对象,以淫羊藿苷含量为淫羊藿品质标准,运用MaxEnt模型和地理信息技术,对影响淫羊藿品质的环境因子进行筛选分析.结果显示,淫羊藿苷含量与7月份水蒸气压呈线性回归关系(F=26.331,P=0.000,r=0.703,R^(2)=0.494),淫羊藿苷含量随着7月份水蒸气数值增加逐渐降低,在适宜淫羊藿生长的河道两边,距离河流越远淫羊藿苷含量越高,药材品质越好.本研究表明,MaxEnt模型和地理信息技术可作为研究影响野生淫羊藿品质变化的一种有效方法,指导淫羊藿药材资源的保护与开发.As a wild medicinal herb,the quality of Epimedium brevicornu Maxim.is affected by the natural environment.In order to study the quality change trend of E.brevicornu Maxim.,this study selected E.brevicornu Maxim.in the Taohe River basin in southern Gansu province as the research object,the content of icariin was taken as the quality standard,MaxEnt model and geographic information technology were used to analyze the correlation between icariin content and the environmental factors.The results showed that there was a linear regression relationship between the content of icariin and water vapor pressure in July(F=26.331,P=0.000,r=0.703,R^(2)=0.494),and the content of icariin gradually decreased with the increase of water vapor pressure in July.On both sides of the river that is suitable for the growth of E.brevicornu Maxim.,the further the distance from the river,the higher the content of icariin,and the better the quality of the medicinal material.In this study,the MaxEnt model and geographic information technology could be used as an effective method to study the quality changes of wild E.brevicornu Maxim.,and guide the protection and development of its medicinal resources of it.
