摘要
目的:为丹参科学引种和规范栽培提供参考。方法:查阅全球生物多样性信息网络数据库等并结合实地调研情况,收集文献记载的野生分布区、栽培主产区及历史分布区共697个丹参样点,采用Spearman系数法对35个生态因子进行相关性检验,并结合文献筛选生态因子指标,建立MaxEnt预测模型,采用刀切法中的ROC曲线评价预测模型的准确度,再根据模型计算出丹参在全球范围内的存在概率,进而利用ArcGIS 10.3软件绘制丹参全球范围内的潜在生态适宜产区图。结果:筛选出6个环境因子指标,分别为年均温、最热季均温、最冷季均温、年均降水量、年均日照和年均相对湿度。刀切法分析表明,气温是影响丹参分布的重要生态因子。丹参全球潜在生态适宜产区主要分布在亚洲东部和北美洲中东部等地区,其生态适宜产区面积约为79.16×105km^2。全球范围内适宜丹参种植的国家主要有中国、美国、俄罗斯、日本、韩国、朝鲜等;我国的丹参潜在生态适宜产区主要包括湖南、湖北、河南、江西、山东等地。结论:全球范围内丹参潜在生态适宜产区主要为亚洲东部及北美洲中东部地区,在引种栽培过程中需要注意种植基地的选择及种植温度的调控,以促进高品质丹参药材的生产。
OBJECTIVE：To provide reference for scientific introduction and standard cultivation of Salvia miltiorrhiza.METHODS：By reviewing global biodiversity information network database,etc.,based on field research,697 S. miltiorrhiza sample sites were collected from wild distribution area, main production area and historical distribution area recorded in literature. Spearman coefficient method was used for correlation test of 35 ecological factors. MaxEnt prediction model was established according to literature screening ecological factor index,and using the ROC curve in the Jackknife method to evaluate the accuracy of the prediction model. According to the model,existence probability of S. miltiorrhiza globally was calculated.ArcGIS 10.3 software was used to draw global potential ecological suitable areas of S. miltiorrhiza. RESULTS：Totally 6 environment factor indexes were screened,including mean annual temperature,mean temperature of the hottest season,mean temperature of the coldest season,annual precipitation,annual sunshine and annual relative humidity. Jackknife method showed temperature was an important environmental factor affecting the distribution of S. miltiorrhiza. The potential ecological suitable areas of S. miltiorrhiza were mainly in the eastern Asia and central and easten of North America,and ecological suitable areas for S. miltiorrhiza was 79.16 × 10^5km^2. At the global level,S. miltiorrhiza mainly distributed in China,the United States,Russia,Japan,South Korea,North Korea,etc. The potential ecological suitable areas in China mainly included Hunan,Hubei,Henan,Jiangxi,Shandong,etc. CONCLUSIONS：The potential ecological suitable areas for S. miltiorrhiza are mainly in the eastern Asia and central and easten of North America. In the process of introduction and cultivation,great attention should be attached to the selection of planting base and the regulation of the growth temperature of S. miltiorrhiza,so as to promote the production of high quality S. miltiorrhiza.
