南药化橘红全球产地适宜性分析

Ecological Suitablility Research of Citri Grandis Exocarpium by GMPGIS

目的:通过化橘红全球产地适宜性分析,为南药化橘红的合理种植和科学产地规划提供重要依据。方法:以化橘红主产区的95个样点为分析基点,结合气温、相对湿度、日照强度、年降水量、土壤类型等关键生态因子值,采用药用植物全球产地适宜性区划信息系统(GMPGIS)对化橘红在全球的生态适宜区域进行分析。结果:化橘红的最大生态相似度区域主要分布于中国、巴西、美国和越南等国家的热带和亚热带区域,总面积约210万km2,其中中国占总面积的60%以上;中国适宜区主要分布于广西、湖南、江西、云南和广东等省。结论:本研究结果为合理规划化橘红种植生产布局,发展引种栽培工作提供了科学参考依据。

Objective：To supply the scientific data for the choice of medicinal plants′ suitable habitat through ananlyzing the approriate producing area of Citri Grandis Exocarpium growth by mean of GMPGIS.Methods：We seleceted 95 distribution in the traditional growing areas as the targets for the study,some key factors related to plant growth such as temperatures,relative humidity,illumination intensity,annual precipitation,and soil type were chosen from GMPGIS database,using GMPGIS（Global Gegoraphic Information System for Medicinal Plant）to analyze the areas desirable for growing Citri Grandis Exocarpium.Results：Analysis result showed that the potential areas desirable for growing in the tropical regions and subtropical regions around the world.The total area is 2 100 823.02 km2.Conclusion：The GMPGIS is much valuable to sort out the appropriate growing area for Citri Grandis Exocarpium,it also provides scientific reference for transplanting and cultivation of Citri Grandis Exocarpium.
