补骨脂全球适宜性区划研究

中药材的引种是扩大药材生产、满足市场需求的重要途径，但不科学的引种会削弱药材的道地性，导致药材质量下降，影响临床疗效。因此，对药用植物道地产区、野生分布区的气候条件和土壤条件的相似性进行分析十分重要。采用中国中医科学院中药研究所自主研发的“药用植物全球产地生态适宜性区划信息系统”（GMPGIS），以本草文献记载的道地产区、野生分布区以及当前主产区126个样点的生态环境因子值为计算依据，经过生态相似性比对分析，获得补骨脂全球范围内的最佳生态适宜产区和潜在种植区，主要包括中国、美国、澳大利亚、墨西哥、印度等国家。其中，补骨脂在中国的生态适宜产区主要包括云南、四川、广西、湖南、湖北、重庆等省区。本研究为补骨脂的规模化种植、引种栽培和保护抚育提供了科学依据，合理的选地标准为高品质补骨脂的科学生产奠定了基础。

A Suitability Research of Global Ecological Regions of Psoralea corylifolia Linn.

The introduction of Chinese medicinal materials is a criticle routine for expanding the production scale of medicinal materials,which meet current market demands.However,inappropriate introduction of indigenous medicinal materials has depressed their medical properties,bringing adverse effects on the quality of medicinal materials and their clinical efficacy.Therefore,it is particularly important to implement similarity analysis of the climate and soil conditions in the indigenous producing areas and wild distributions of medical plants.In this study,a zoning information system for the ecological suitability of global producing areas,global geographic information system for medicinal plant(GMPGIS),was developed by Institute of Chinese Materia Medica,China Academy of Chinese Medical Science.According to the ecological environment factors from 126 sampling sites in the indigenous producing areas recorded in acient herbal literature,wild distributions and current mainstream producing areas,the optimum suitable ecological regions and potential planting zones of scurfpea fruit were output by ecological similarity comparison analysis.China,the United States,Australia,Mexico,India and some other countries were involved in the ecological regions and planting zones.In China,the optimum ecological regions consisted of Yunnan,Sichuan,Guangxi,Hunan and Hubei provinces.In conclusion,this study laid a foundation for a prudent produce of high-quality scurfpea fruit with reliable selection standards and provisions of the scientific evidence behind its large-scale planting,introduction,cultivation, preservation and nurture.
