在野外调查和数据收集的基础上,结合药用植物全球产地生态适宜性分析系统(geographic information system for global medicinal plants,GMPGIS),对中药重楼全球产地生态适宜性区域进行分析和评价.以重楼药材基原物种云南重楼Paris polyphylla var.yunnanensis和七叶一枝花P.polyphylla vat.chinensis道地产区、主产区与野生分布区的采样点为依据,选取最冷季平均气温、最热季平均气温、年平均气温、年均降水量、年均相对湿度、年均日照强度和土壤类型7个生态指标作为主要参考因子,经过生态相似性比对分析得出云南重楼与七叶一枝花在全球范围内的生态适宜性产区和潜在种植区.结果表明云南重楼和七叶一枝花的最大生态相似度区域相似,在全球范围内主要分布在中国、巴西、美国、赞比亚、刚果、缅甸、坦桑尼亚、墨西哥、安哥拉及玻利维亚等19个国家.其中,中国的最大生态适宜性产区主要包括云南、四川、广西、湖南、湖北、广东、贵州、江西、福建和安徽等16个省区.该研究表明GMPGIS可以较好地应用于中药材引种及生产区划,研究结果可为重楼药材的资源保护和可持续利用提供参考依据.
Global Ecological Suitability of Paridis Rhizoma Based on GMPGIS
For assessing the global production and ecological adaptation of Paridis Rhizoma and providing the scientific basis for its production,geographic information system for global medicinal plants (GMPGIS) was used to predict the ecological suitability areas of Paris polyphylla var.yunnanensis and P.polyphylla var.chinensis.Seven conditions,including annual mean temperature,annual precipitation,annual mean radiation,annual mean relative humidity and soil type of P.polyphylla var.yunnanensis and P.polyphylla var.chinensis were selected.The candidates regions covered both traditional and current major producing regions.The result showed that the suitable area for P.polyphylla var.yunnanensis and P.polyphylla var.chinensis growth mainly involved 19 countries,such as China,Brazil,the United States and so on.The ecological suitability regions of P.polyphylla var.yunnanensis and P.polyphylla var.chinensis in China mainly distributed in Yunnan,Sichuan,Guangxi and other 13 provinces.The result demonstrated that GMPGIS was a scientific and valuable tool for the ecological suitability analysis of medicinal plants.This analysis also provides a scientific basis for cultivation and protection of Paridis Rhizoma.
