摘　　要：应用ArcGIS和Maxent模型分析栀子在全国的生态适宜性。以85批栀子药材为分析基点,选取适合栀子生长的生态因子。研究结果表明4月均降水量、11月均降水量和8月均温度等是影响栀子的生长最关键的生态因子,栀子适宜生长区域相对集中,北至陕西南部、河南南部、安徽中部,南至海南省北部,西至四川省中部,东至浙江沿海地区、台湾东北部。The application of ArcGIS and Maxent modeho analyze the ecological suitability of Gardenia jasminoides. Taking 85 bat- ches of Gardenia as the basis of analysis, the selection of ecological factors for the growth of Gardenia. The results showed that the av- erage precipitation in April, the average precipitation in November and the average precipitation in August were the most important fac- tors affecting the growth of Gardenia. The relative concentration of Gardenia suitable growth region, north to the south of Shaanxi prov- ince, south of Henan, central Anhui, south to the north of Hainan province, west to central Sichuan province, east of Zhejiang coastal area, northeast of Taiwan.
