垂珠花的分布特征分析及潜在适生区预测
Analysis of distribution characteristics and prediction of prospective suitable areas of Styrax dasyanthus
为探索垂珠花分布特性及潜在适生区,基于 145条现代分布记录及 18个气候环境因子,利用刀切法,标准差椭圆计算及多元相似度面和最不相似变量分析后发现,其适生区空间分布格局向"正北-正南"方向扩张,质心有由中亚热带往北亚热带迁移的趋势,未来气候条件下温度与降水共同制约垂珠花的分布,温度因子是驱动其适生区迁移的关键因素,但降水因子与垂珠花的潜在分布关联性更强。垂珠花的现代中高度适生区主要集中在我国江苏、安徽、江西、浙江、湖南的大部分地区;未来两种气候情景对垂珠花生存有正向影响,中高度适宜区面积存在增加现象。
Based on 145 records of modern distribution and 18 climatic and environmental factors,the method of knife-cutting was used for studying the distribution features and prospective adaptive area of Styrax dasyanthus Perk.,and Standard Deviation Ellipse Calculation,Multivariate Similarity Surface,Least Similarity Variable analysis as well,the results show that the spatial distribution pattern of the adaptive habitat expands to"North-South"direction,and the centroid has a move trend from the Mid subtropics to the North subtropics.Under the future climatic conditions,temperature and precipitation will jointly restrict the distribution of S.dasyanthus,and temperature is the key factor to drive the migration of the adaptive area.The modern medium and high adaptive zones of S.dasyanthus are mainly cover the most regions of Jiangsu,Anhui,Jiangxi,Zhejiang and Hunan in China,and the 2 prospective climate scenarios have positive impacts on the survival of S.dasyanthus.The area of medium and high suitable area may expand.
