中文摘要 全球变暖背景下,高温热浪等极端天气气候事件已成为一个常态。2022年夏季我国出现了持续的高温晴热天气,导致大量园林植物生长不良,甚至死亡,因此,调查和评估高温晴热天气下园林植物的生长状况尤为重要。文章以武汉市为例,在持续晴热26天后,对10个公园绿地和9个居住区绿地的园林植物叶片及植株进行样方调查,根据叶色的枯黄等生长状态进行受害等级赋分,并进行植物区系分析。结果表明:受害严重的园林植物主要为温带区系成分,而热带区系成分的植物受影响较少。在一定范围内,群落的物种丰富度增加,植物的受害等级降低;乔木层和灌木层丰富度增加,其受害等级先增加后降低,当乔、灌木层的丰富度达到6种时,受害等级较低,草本层植物的丰富度与受害等级的相关性不明显。因此,高温晴热天气对武汉市区的园林植物产生了不同程度的影响,在武汉地区适当增加热带区系成分的植物更能适应未来的气候变化。

英文摘要 Under the background of global warming, it is common to experience extreme weather events such as heat waves. In the summer of 2022, the continuous hot weather in China led to poor growth and even death of a large number of landscape plants. Therefore, it is necessary to investigate and evaluate the growth of landscape plants in hot weather. The paper investigates the leaves of landscape plants and individual plants in 10 park green spaces and 9 residential green spaces in Wuhan City using sampling method, after 26 days of continuous hot weather, and assigns the damage grade according to the growth state of plants, such as withered and yellow leaf color. Then the flora is analyzed. The results show that severely affected landscape plants are mainly of temperate flora, while those of tropical flora are less affected. Within a certain range, the species richness of the community increases and the damage level of plants decreases. When the richness of arbor layer and shrub layer increases, the damage level first increases and then decreases. When the richness of arbor layer and shrub layer amounts to 6 species, the damage level is low, and the correlation between the richness of herbaceous layer and the damage level is not obvious. In this sense, hot weather has different effects on landscape plants, and appropriate increase of tropical flora in Wuhan could make the city more adaptable to future climate change.
