胖大海全球产地适宜性分析

Ecological Suitability Assessment of Sterculia Lychnophora Hance

目的:本研究分析了胖大海全球产地适宜性,为其科学区划及种植提供依据。方法:以胖大海原产地、主产地及主要分布区的97个样点为分析基点,选取气温、相对湿度、日照强度、年降水量、土壤等关键生态因子值,采用药用植物全球产地适宜性区划信息系统(GMPGIS)对胖大海在全球的生态适宜区域进行分析。结果:胖大海最大生态相似度区域主要分布在热带地区,适宜区的分析结果覆盖了文献记载的全部胖大海分布区域;同时还发现了胖大海潜在生产适宜区。结论:本研究结果可为合理规划胖大海种植生产布局,开展引种栽培工作提供科学依据。

This study aimed to explore appropriate global appellations of Sterculia lychnophora Hance and provide scientific evidence for its rigorous zoning and planting. 97 sites from the original appellations, main producing areas and distributions were selected to evaluate the desirable areas for yielding S. lychnophora Hance, taking temperature, relative humidity, illumination intensity, annual precipitation and soil type as key factors analyzed by Global gegoraphic information system for medicinal plant （GMPGIS） database. As a result, it was found that the appellations of S. lychnophora Hance was distributed in tropic regions based on the maximum ecological similarity. The suitable producing areas analyzed by GMPGIS covered all the areas registered in documents. It was also found some new and potential appellations for producing S. lychnophora Hance. In conclusion, it was demonstrated that the GMPGIS was much valuable to pinpoint the appropriate appellations for yielding S. lychnophora Hance, and to provide a prudent reference for its transplantation and cultivation.
