中文摘要	为研究气候变化对4种扁桃亚属植物在中国潜在适生分布区的影响,本文收集4种扁桃亚属植物的193个地理分布坐标和19个生物气候变量,利用MaxEnt生态位模型预测扁桃(Amygdalus communis L.)、矮扁桃(Amygdalus nana L.)、蒙古扁桃(Amygdalus mongolica(Maxim.)Ricker.)和西康扁桃(Amygdalus tangutica (Batal.)Korsh.)在中国过去(末次间冰期和末次冰盛期)、当代和未来(2050年)4个时期气候条件下的潜在适生区。结果表明:当代气候条件下,扁桃主要分布于中国新疆裕民县、巩留县、莎车县、英吉沙县、和田县、乌鲁木齐等地区,与过去相比,乌鲁木齐地区的低适生区面积有所减少;与当代相比,未来气候条件下扁桃的适生区面积增加0.17%,甘肃省酒泉市境内低适生区面积增加。当代气候条件下,矮扁桃主要分布于新疆布尔津县、额敏县和裕民县等;与过去相比,矮扁桃总分布面积主要在布尔津县和额敏县等地区,先减小再增加;与当代相比,未来气候条件下总分布面积减少0.85%;当代气候条件下,蒙古扁桃主要分布于东戈壁、呼和浩特和阿拉善戈壁、鄂尔多斯市等地区;与过去相比,蒙古扁桃的适生区分布面积先减小再增加;与当代相比,未来气候条件下分布面积减少3.39%;当代气候条件下,西康扁桃主要分布于四川省马尔康县、茂县等地区;与过去相比,西康扁桃适生区分布面积呈现出增长趋势;与当代相比,未来气候条件下总面积增加0.25%,低适生区面积有所增加。年均降水量是影响扁桃地理分布的主要环境因子;降水量变异系数是影响矮扁桃的主要环境因子;温度季节性变化标准差是影响蒙古扁桃和西康扁桃的主要环境因子。
英文摘要	To clarify the impacts of climate change on the geographic distribution of four species of subgen.Amygdalus in China,we collected 193 geographic coordinates and 19 bioclimatic variables of four species of subgen.Amygdalus.The potential suitable areas of A.communis,A.nana,A.mongolica,and A.tangutica under the climatic conditions of the past times (the last interglacial period and the last glacial maximum period),current and future periods (2050s) were predicted using MaxEnt models.The results showed that,under current climate,the suitable areas of A.communis are mainly distributed in Yumin,Gongliu,Shache,Yingjisha,Hetian counties,and Urumqi of Xinjiang.The area with low suitability for A.communis in Urumqi has decreased compared to the past.Compared with the current climae,the total area with low suitability under the future climate conditions would increase by 0.17%,mainly due to increased area in Jiuquan of Gansu Province.Under current climate conditions,the suitable areas of A.nana are mainly distributed in Buerjin,Emin,Yumin counties of Xinjiang.Compared to the past,the total distribution area of A.nana decreased first and then increased in Buerjin and Emin counties.Under the future climate conditions,the total distribution area of A.nana would decrease by 0.85%.Under current climatic conditions,the suitable area of A.mongolica is mainly distributed in East Gobi,Hohhot,Alax Gobi,and Ordos of Inner Mongolia.Compared to the past,the total distribution area of A.mongolica decreased first and then increased.Under the future climate conditions,the distribution area of A.mongolica would decrease by 3.39%.Under current climate,the suitable area of A.tangutica is mainly located in Maerkang and Maoxian counties of Sichuan;which has increased compared to the past.Under the future climate conditions,the total area of A.tangutica would increase by 0.25% mainly due to the increased lowly suitable area.Mean annual precipitation is the main environmental factor affecting the distribution of A.communis,while precipitation seasonality (coefficient of variation) is the main environmental factor affecting that of A.nana.Temperature seasonality (standard deviation*100) is the main environmental factor affecting the distribution of A.mongolica and A.tangutica.
