中文摘要: 原产于南美洲的牛膝菊(Galinsogaparviflora)在我国已造成大面积入侵,然而当前尚不清楚该种在中国的适生区范围,以及气候变化对其适生区分布产生的影响。本研究利用最大熵模型(MaxEnt)分析了在当前(2000s)气候条件下该入侵种在中国的适生区范围,以及在气候变化背景下其未来(2050s和2080s)的适生区变化。模型受试者工作特征曲线下面积(AUC)达0.804,模拟效果良好。影响牛膝菊分布的环境因子主要为温度(包括bio_1、bio_4、bio_6、bio_7、bio_9、bio_ 10和bio_11)。模型结果显示,牛膝菊的极高适生区主要集中在西南地区的云南、贵州、四川、福建和台湾,这也正是该种目前在中国危害最严重的地区。气候变化将会导致其在广东、广西和华北地区的适生区出现缩减,甚至消失;而其适生区的北界将进一步向高纬度地区移动。总体而言,到本世纪末(2080s),其在中国的适生区面积将随着气候变化而呈现减小趋势。当前牛膝菊在中国的潜在入侵区域较大,该种对我国青藏高原以东广大地区的入侵潜力巨大,但是其未来的入侵进程可能受到气候变化的抑制。
英文摘要: Galinsogaparviflorais an annual herbaceous plant originating in South America,and has caused great harm to agriculture in China.However,the distribution and influence of this invader are poorly documented yet.Besides,it is still unclear how the changing climate will affect the expansion of G.parviflorain China.With these questions in mind,we studied the effects of climate change on its future geographical distributions in China using maximum entropy(Max-Ent)model based on the climatic data lately released by the ${5^{{
