摘  要：
基于猫爪草的140个分布位点和10个环境变量,采用最大熵模型(MaxEnt)和地理信息系统(GIS)对猫爪草在我国的适生区进行预测。结果表明,ROC曲线面积AUC值为0.92,说明模型预测结果可靠;猫爪草在我国的高度适生区主要集中在长江流域平原各省区,包括河南省南部、安徽省中南部、江苏省南部、上海、浙江省东部和北部、江西省北部、湖北省南部、湖南省中部以及重庆的部分地区和台湾北部,面积约占我国土地面积的3.3%;影响猫爪草分布的主导环境因子与降水和温度有关,包括3月份降水量、降水量季节变化、等温性和温度季节性变化标准差。这些结果与猫爪草的实际分布和生物学特性相吻合,可为其推广种植提供参考。

摘  要：
Based on distribution data of 140 sites and 10 environmental factors of Ranunculus ternatus,the MaxEnt model and geographic information system(GIS) were used to predict potentially suitable habitats of R.ternatus.The results showed that the AUC value of the area under the receiver operation characteristic curve(ROC) was 0.92,indicating that the model prediction results were reliable.The highly suitable areas of Ranunculus ternatus in China were mainly concentrated in the provinces of the Yangtze River Basin, including the southern Henan Province, central and southern Anhui Province, southern Jiangsu Province, Shanghai, eastern and northern Zhejiang Province, northern Jiangxi Province, southern Hubei Province and central Hunan Province, part of Chongqing and north of Taiwan, covering an area of about 3.3% of China's land area.The dominant environmental factors affecting the distribution of Ranunculus ternatus were related to precipitation and temperature, including precipitation in March, seasonal changes of precipitation, isotherm and standard deviation of seasonal changes in temperature.These results are consistent with the actual distribution and biological characteristics of Ranunculus ternatus,and can provide a reference for its promotion and planting.
