Abstract: To evaluate the distribution of the traditional Chinese medicine Polygonati Rhizoma in China and the main environmental factors affecting its distribution by means of ecological niche modelling, a total of 679 geographic locations of Polygonati Rhizoma distribution were collected, and combined with 19 climatic and 4 topographic factors to simulate and analyze current and future habitat suitability by using MaxEnt algorithm and GIS technology, respectively. Currently, the total suitable area for Polygonati Rhizoma is 2 142 500 km2, mainly including Zhejiang, Jiangxi, eastern Yunnan, southern Sichuan, Chongqing and Hunan. Under future climate scenarios, the centre of mass migration is located in southern Shaanxi, northern Henan and Shanxi provinces, and the areas of both its high suitable and more suitable zones show an expanding trend, while the area of low suitable zones decreases and then increases. The key environmental factors affecting the distribution of Polygonati Rhizoma were elevation (200-3000 m), mean temperature of driest quarter (-5 ℃~5 ℃), precipitation of the driest month (19-215 mm) and precipitation of the warmest quarter (480-1500 mm). The MaxEnt model used in this study predicted accurate and reliable results (AUC=0.824), which provides a certain reference basis for the study of wild resources conservation and introduction of cultivation of Polygonati Rhizoma.

摘要: 通过生态位模型评价中药黄精(Polygonati Rhizoma)在我国的分布情况及影响其分布的主要环境因子,收集了679个黄精分布地理位点,与19项气候因子和4个地形因子相结合,采用MaxEnt算法和GIS技术分别对当前和未来的生境适宜性进行模拟分析。当前黄精总适生区面积为2 142 500 km2,主要包括浙江、江西、云南东部、四川南部、重庆和湖南。在未来气候情景下,质心迁移中心位于陕西南部、河南北部和山西省,其高适生区和中适生区面积均呈现扩大趋势,而低适生区面积先减少后增加。影响黄精分布的关键环境因子为海拔(200~3000 m)、最干季度平均气温(-5 ℃~5 ℃)、最干月降水量(19~215 mm)和最暖季度降水量(480~1500 mm)。本研究采用MaxEnt模型预测结果准确可靠(AUC=0.824),为黄精野生资源保护和引种栽培研究提供了一定的参考依据。
