摘要:
微毛樱桃是具有极高观赏价值的乡土树种。该文基于微毛樱桃分布数据和环境气候因子,使用MaxEnt模型和ArcGIS模拟微毛樱桃当代、未来(2050年代和2070年代)2种气候变化情景下的潜在适生区分布,分析当代和未来气候情景下微毛樱桃在中国的潜在适宜分布区域,确定影响其分布的主要气候因子,为合理引种栽培和资源保护提供参考。研究结果如下:(1)模型的受试者工作特征曲线下面积(AUC)值为0.943,预测结果可信度高。(2)年降水量、最冷月最低温和温度季节性变化系数这3个环境因子贡献率最高,分别达到36.3%,27.5%和15.6%;刀切法检验中,这3个环境因子得分最高。(3)当代微毛樱桃的适生区主要集中于西南、西北、华中以及华东地区,而高适生区主要集中在华中地区,西南、西北地区也有分布;未来微毛樱桃潜在适生区范围将增加,高适生区在华中地区的范围进一步扩张。通过MaxEnt模型预测结果分析可得,水分因子和温度因子共同限制了微毛樱桃的地理分布;未来微毛樱桃的潜在适生区面积将持续增加。认为华中地区可扩大微毛樱桃种植规模,充分发挥其生态经济价值。
Abstract:
Cerasus clarofolia is a native tree with extremely high ornamental value.Based on the distribution data and environmental climatic factors of C. clarofolia, in this article, MaxEnt model and ArcGIS were used to simulate the distribution of its potential suitable areas (PSAs) under two climate change scenarios at current, 2050s and 2070s. After the PSAs analyzed in China under two scenarios, the main climatic factors affecting its distribution were determined. The results showed that (1) The area under the receiver operating characteristic curve (AUC) value of the model was 0.943, indicating a highly reliable prediction. (2) The annual precipitation, the min temperature of coldest month and the temperature seasonality had the highest contribution rates, reaching 36.3%, 27.5% and 15.6% respectively, all getting the highest scores by using jackknife method. (3) Under modern climatic conditions, the suitable areas are mainly concentrated in the southwest, northwest, central and eastern China, and the highly suitable areas mainly concentrated in central China, also distributed in the southwest and northwest regions. Under the prediction of future climate change, its PSA will spread especially in central China. It could be concluded that precipitation and temperature factors jointly limited its geographic distribution; and with the future climate change, its PSA would continue increasing. So central China can expand the planting scale of C. clarofolia and realize improve ecological and economic value.
