用MaxEnt模拟湖北海棠(Malus hupehensis)地理分布
Modelling geographic distribution of Malus hupehensis with MaxEnt
摘要
Abstract
Geographic distribution of Malus hupehensis was modelled with MaxEnt by 551 presence recorded data and current bioclimatic data.The results showed that:①Malus hupehensis would be more likely to occur in those areas (potential distribution),such as northern Pakistan,northern India,Nepal,Bhutan,northeast Myanmar,northwest of Vietnam,northern of Guangxi,the southern and southeastern of Xizang,southeast of Japan,south,center and coast of Korea,northeast of Hebei,north of Shandong,southern of Liaoning.Of which,the areas with 0.6-1 distribution value (logistic) are Bhutan,Cheju Island and coastal islands of Korea,Japan islands and the its nearby islands.② The areas with distribution values 0.6-1 were in the southeast of Shanxi,Nantong of Jiangsu,Hanyuan of Sichuan,and Laoshan of Shandong,although,there were a few present records in those areas.③ Geographical distribution patterns of M.hupehensis could be expressed using those areas with distribution value 0.6-1,from west to east,the southern and southeastern of the Himalayas,Hengduan Mountains,Qinling Mountains,and Wu Mountains,the mountainous regions of middle and lower reaches of Yangtze River,Wuyi Mountains,Korean Peninsula,the Japan islands.From north to south,the most northern boundary was in the south of the Taihang Mountains,and the southern boundary was in the southwest of the Wuyi Mountains.④ It was showed that the average temperature in the dry season was the greatest contribution to the distribution gain of M.hupehensis by Jackknife Test,and it was distributed naturally over those areas with average temperature of-10℃-15℃ in the dry season.关键词
