Effect of Climate Factors on Potential Distribution of Jasminum sambac in China

Based on ArcGIS and MaxEnt model, 85 distribution records of wild Jasminum sambac and 19 climate variables were used to simulate its current and future niches. The results showed that the area under receiver operating characteristic curve was 0.982, indicating an extremely high accuracy of the model prediction. The current distribution of J. sambac was mainly affected by temperature (mean annual temperature, ANOVA of temperature change, mean temperature in the driest season, mean temperature of the warmest season) and precipitation (in the wettest season and the warmest season). Under the current climate condition, the optimum habitat of J. sambac mainly distributes in the southwestern Guangdong, the borders of Yunnan, Sichuan and Chongqing, northern Hunan, southern Henan, central Anhui, and central Jiangsu. In the future (2050) with climate
