基于MaxEnt 模型的毛红椿全球潜在适生区分布及其特征预测研究
Prediction of Global Potential Suitable Distribution Areas and Attributes of Toona ciliata var. pubescens with MaxEnt
摘要
Abstract
A maximum entropy model(MaxEnt)was used to investigate the prediction of the global poten-tial distribution areas of T.ciliata var.pubescens and the key factors in its distribution.As a result,its pattern of the global geographical distribution was continuous,while the high distribution areas followed a patchy pattern. The climatic factors that were found to affect the distribution of T.ciliata var.pubescens were mainly precipitation of the warmest quarter,SD of temperature seasonality and min temperature of the coldest months,with the suit-able value ranges being 494.79-1 504 mm,2 362.88-9 986.69,-10.35-10.44 ℃,respectively.The continu-ous distribution in China is better than abroad,and there were two patches of most suitable distribution,one of which is located in the southeast of Anhui Province and Zhejiang Province,and the other in Fujian Province, Guangdong Province,and in the south of Jiangxi Province.The regions of the two patches are basically coinci-dent with the existing research areas with higher genetic characters.fherefore they should be included in the ar-eas under prior protection in further study.关键词
