摘要: 为预测未来气候变化对我国特有珍稀植物沙生柽柳(Tamarix taklamakanensis)潜在适宜分布的影响,选用过去气候(1961—1990年)、2050年气候、2070年气候3种情景,利用Maxent模型模拟沙生柽柳潜在分布的动态变化。结果表明:① 沙生柽柳的适宜潜在分布区主要集中在我国塔里木盆地、吐鲁番盆地、库姆塔格沙漠、内蒙古阿拉善荒漠的西北部,最适宜的潜在分布区位于塔里木盆地腹地及盆地东部的库木塔格沙漠地区;② 与过去潜在分布范围相比,未来2050年和2070年气候背景下,沙生柽柳的最适宜潜在分布范围均有萎缩趋势;③ 影响沙生柽柳潜在地理分布的主要气候因子为最干季降水量、年降水量、年平均气温、最暖季降水量。

Abstract: In order to predict the impact of future climate change on the potential suitable distribution of Tamarix taklamakanensis,a rare endemic plant species in China,the climate situations in the past (1961-1990),2050 and 2070 were selected to simulate the dynamic change of the distribution of T. taklamakanensis in the Kumtag Desert using the Maxent model. The research results are as follows:① The suitable distribution areas of T. taklamakanensis would be the Tarim Basin,Turpan Basin,Kumtag Desert,and northwest region of the Alxa Desert in Inner Mongolia,and the most suitable potential distribution area would be the Kumtag Deser in the hinterland and the eastern part of the Tarim Basin;② Compared with the past potential distribution of T. taklamakanensis, the most suitable potential distribution areas would be shrunk in both 2050 and 2070;③ The climatic factors affecting the potential distribution of T. taklamakanensis would be mainly the precipitation in the driest season,annual precipitation,annual temperature and precipitation in the warmest season.
