Investigation on the ecological suitable regionalization of Melicope ptelefolia

Objective: The aim of paper is to find ecological suitable regionalization of Melicope ptelefolia planting and provide a reference for the rational planning of Good Agricultural Practices (GAP). Methods: The natural ecological niches of Melicope ptelefolia was taken as basic point. The adaptable areas of Melicope ptelefolia was analysed throughout the whole nation by using Geographic Information System for Traditional Chinese Medicine (TCMGIS). Results: Besides the original distribbution region of Guangxi, Guangdong, Hainan, Yunnan, Fujian, Jiangxi, Hunan, Guizhou, we further found that Zhejiang, Taiwan, Hong Kong, Chongqing, Sichuan are adaptable for the growth of Melicope ptelefolia. The most suitable region is Guangxi, and the followed is Guangdong. Conclusion: The ecological suitable area of Melicope ptelefolia mainly distributes in Lingnan Region, and TCMGIS is comparatively scientific and accurate to analyze suitable areas for the growth of Melicope ptelefolia. These findings have important reference value for the introduction, cultivation and scientific planning of Melicope ptelefolia.
