To study the ecological suitability of Roumao Yinyanghuo(Epimedium pubescens Maxim.),explore the potential suitable cultivation sites of Roumao Yinyanghuo(Epimedium pubescens Maxim.)and promote the development and utilization of the resources of Roumao Yinyanghuo(Epimedium pubescens Maxim.).
Based on field research,literature collection and the Chinese Digital Herbarium,a total of 68 items of valid point data were collected,and 54 ecological factors were selected according to the physiological habits of Roumao Yinyanghuo(Epimedium pubescens Maxim.),and the potential climatic suitability zones of Roumao Yinyanghuo(Epimedium pubescens Maxim.)in China were investigated by the Maximum Information Entropy(MaxEnt)model.
CI index,April precipitation,annual sunshine duration,elevation,January mean temperature and HI index were six ecological factors that had a greater impact on the distribution of Roumao Yinyanghuo(Epimedium pubescens Maxim.),which was mainly distributed in Gansu and southern Shaanxi,north-central Sichuan,north-central Guizhou,southeastern Chongqing and southern Hunan in China.
The climatic suitability zones of Roumao Yinyanghuo(Epimedium pubescens Maxim.)in this experiment was basically consistent with the range described in Flora of China(2004 Edition),which can provide a reference for the investigation,exploitation and sustainable development of Roumao Yinyanghuo(Epimedium pubescens Maxim.)in China.
