has strong resistance to drought, cold, salt, and rust. It is one of the main rootstock types of pear in Northwest China, with high production value. However, its habitat is seriously damaged. The prediction of the geographical distribution of under different climate scenarios will provide important scientific basis for rational development and utilization of resources and the protection of diversity. Based on MaxEnt model and ArcGIS spatial analysis, the potential spatial distribution pattern of in the current and future (2050, 2070) was constructed using comprehensive and accurate distribution records and high-resolution environmental data, and the relative importance of environmental factors was evaluated. The results showed that the suitable habitat area of was 3.32×10 km, mainly located in eastern Qinghai, southern Gansu, southern Ningxia, central Shaanxi, southern Shanxi and western Henan. Mean UV-B of the month with lowest UV-B and altitude were identified as the critical factors shaping habitat availability for Overall, with global warming, the potential habitat for might decrease in 2050 and 2070 under different CO climate scenarios. Real-time monitoring of populations should be enhanced.
具有很强的抗旱、抗寒、抗盐和抗锈能力。它是中国西北梨树的主要砧木类型之一，具有很高的生产价值。然而，其栖息地遭到严重破坏。预测不同气候情景下[物种名称]的地理分布，将为合理开发利用资源和保护生物多样性提供重要的科学依据。基于最大熵模型（MaxEnt）和ArcGIS空间分析，利用全面准确的分布记录和高分辨率环境数据，构建了[物种名称]在当前及未来（2050年、2070年）的潜在空间分布格局，并评估了环境因子的相对重要性。结果表明，[物种名称]的适宜栖息地面积为3.32×10[具体单位]平方千米，主要分布在青海东部、甘肃南部、宁夏南部、陕西中部、山西南部和河南西部。月平均紫外线B辐射量最低的月份的平均紫外线B辐射量和海拔被确定为影响[物种名称]栖息地可利用性的关键因素。总体而言，随着全球变暖，在不同的二氧化碳排放气候情景下，[物种名称]的潜在栖息地在2050年和2070年可能会减少。应加强对[物种名称]种群的实时监测。 （注：原文中部分关键物种名称缺失，用[物种名称]表示）
