中文摘要	【目的】欧李作为我国特有的生态型树种,在防风固沙、蓄水保土等方面具有重要的生态和经济价值,因此研究欧李的全球潜在适生区及其生态特征,对欧李树种的推广种植和防沙治理具有重要意义。【方法】本文根据379个欧李分布点和19个生态因子数据,采用BIOCLIM、DOMAIN、MAXENT和GARP 4个生态位模型预测欧李的全球潜在适生区,并分析欧李分布区的生态特征,以受试者工作特征曲线ROC和Kappa两个统计量进行模型评价。【结果】欧李的全球潜在适生区主要分布在30°~52° N、102°~137° E范围内的亚洲,包括中国、韩国、朝鲜以及与中国东北接壤的俄罗斯远东地区,另外,阿富汗和塔吉克斯坦也有少量分布,其中最适宜区主要分布在中国。模型评估表明,4个模型的AUC值均达到0.85以上,Kappa值均达到0.7以上,4个模型预测精度良好,一致性显著,均可用来预测欧李潜在适生区。欧李分布区的生态特征为:年平均温度范围为3.2~13.9 ℃,昼夜温差月均值范围为10.1~13.0 ℃,昼夜温差与年温差比值范围为24~30,温度变化方差范围为9 234~13 581,最湿月份降水量范围为115~226 mm,最干月份降水量范围为2~10 mm,雨量变化方差范围为77~115。【结论】欧李潜在适生区主要位于温带季风气候带,最适宜区主要分布在中国东北和华北地区,该地区可大规模种植欧李以实现荒漠化治理,而韩国、朝鲜、俄罗斯远东区和阿富汗等地适宜性相对较低,可先进行小规模试种,再扩大生产。
英文摘要	[Objective] Cerasus humilis, a unique ecological tree species in China, has significant ecological value and economic value in windproof and sand fixation, so it is important to predict the global potential habitat of C. humilis and analyze its niche, which is beneficial for its cultivation promotion and sand control. [Method] According to 379 distribution points of C. humilis and 19 ecological variables, four ecological niche models (BIOCLIM, DOMAIN, GARP, MAXENT) were used to predict the potential suitable distribution area of C. humilis and analyze its ecological characteristics. The predicted results were evaluated by two statistical criteria, the area under the receiver operating characteristic curve (AUC) and Kappa value. [Result] The results showed that the potential distribution area of C. humilis was mainly located in the range of 30°-52° N and 102°-137° E, including China, South Korea, North Korea, and Russian Far East bordering northeast China. Besides, a small amount of area was located in Afghanistan and Tajikistan as well. Among them, the most suitable area was mainly distributed in China. The model evaluation results showed that the AUC values of the four models were above 0.85 and the Kappa values were above 0.7, indicating their good prediction accuracy and consistency, so they can well predict the potential suitable area of C. humilis. The ecological characteristics of the distribution area for C. humilis were that the range of annual average temperature was 3.2 - 13.9 ℃, the monthly mean value of diurnal temperature difference (max. temperature-min. temperature) was 10.1-13.0 ℃, the range of isothermality was 24 - 30, SD of temperature seasonality ranged from 9 234 to 13 581, precipitation of the wettest month ranged from 115 to 226 mm, precipitation of the driest month was 2 to 10 mm and the variation range of precipitation seasonality was 77 - 115.[Conclusion] Potential suitable distributing area of C. humilis was mainly in temperate zone monsoon climate and the most suitable area was mainly located in northeastern and northern China, where large-scale cultivation of C. humilis can be achieved for desertification management. In Korean, North Korea, Russian Far East and Afghanistan, the suitability was relatively low, so small-scale cultivation trials can be conducted before expanding production.
