双药芒(Miscanthus nudipes)是一种适应寒冷和干旱环境的芒属植物,具备驯化成具有生态修复、观赏等多功能植物的潜力。在双药芒现有分布记录的基础上,采用Maxent模型构建其在末次间冰期、末次盛冰期、现代以及未来(2070年)的潜在分布格局,在评价环境因子对其分布模型影响的前提下,定量分析不同生态气候情景下双药芒适生区域的变化。结果表明:(1)温度变化方差在440—645,最冷月份最低温在-8.5—0℃,年温变化范围在22—30℃,5月降水量在70—115 mm,海拔范围在1630—3750 m,6月太阳辐射小于15800 kJ m~(-2)d~(-1)时适宜双药芒的生长和分布。其中,温度变化方差是影响双药芒地理分布格局的关键性气候...

Miscanthus nudipes is the species which is highly adaptable to extremely cold and drought environments,and has the potential of being domesticated to the species with highly ecological adaptability.Based on the current distribution of the M.nudipes,using the Maxent model to analyze the potential geographical distributions of the M.nudipes in the Last Interglacial Period,the Last Glacial Maximum Period,the Modern Period and in the future (in the year of 2070),respectively.Meanwhile,based on the different species distribution models,this study qu...
