| 中文摘要: |
| 为充分认识大理市低温对榕属植物的危害程度，于2021年2月对市内20个榕树样方进行调查分析，将每个样方的低温受害程度换算为寒害指数并进行统计分析。结果表明：大理市北端、洱海西岸、郊区的榕树分别比南端、洱海东岸、城区的榕树更易遭受低温寒害，而树种差异对受寒害程度没有显著影响。提出在大理榕属植物受低温危害较轻，结合修剪养护等措施大多能恢复，较适于大理市园林绿化应用，建议在低纬度区、城区配置应用。 |

| In order to fully understand the injury degree of low temperature to Ficus in Dali, this study investigated and analyzed 20 Ficus quadrats in February 2021. The low temperature injury degree of each quadrat was transformed into cold injury index to perform statistical analysis. The results showed that Ficus plants were more vulnerable to low temperature cold injury in the north of Dali than those in the south, more vulnerable in the west of Erhai than those in the east, and more vulnerable in the suburbs than those in the urban area, and the difference of tree species showed non-prominent association with cold injury severity. This paper indicated that Ficus plants in Dali were less affected by low temperatures, and most could be restored through measures such as pruning and maintenance, which were more suitable for landscape greening applications in Dali City and were planted in low latitude areas and urban areas. |
