Investigation on the ecological suitable regionalization of Melicope ptelefolia

目的:研究三叉苦的生态适宜性,为GAP合理规划和科学选址提供参考。方法:以三叉苦的主要产区为基点,运用“中药材产地适宜性分析地理信息系统”(TCMGIS)分析三叉苦的全国适宜产区。结果:广西壮族自治区、广东、海南、云南、福建、江西、湖南、贵州、浙江、台湾、香港特别行政区、重庆市、四川等省市适宜三叉苦的生长,其中面积较大的为广西壮族自治区,其次为广东省。结论:三叉苦生态适宜区分布主要在我国岭南地区,这与历史文献记载及现代引种实践数据相吻合,应用TCMGIS技术分析三叉苦生态适宜性具有一定的科学性和准确性,对三叉苦的引种栽培及科学规划具有重要的参考价值。

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.
