摘要/Abstract

摘要：

选择上海辰山植物园内37个园林树种为研究对象, 利用红外热像仪测量其树温 (包含树冠温度和树干温度), 研究了夏季高温环境中树温与叶片生理指标 (净光合速率、蒸腾速率和气孔导度) 和功能性状指标 (叶片面积、叶厚、比叶重和比叶面积) 之间的相关关系, 并分析了不同树种的树温对夏季高温的变化反应及其生理调节机制, 为选择具有良好降温功能的园林树种提供了参考依据. 结果表明: 总体上, 树冠温度比气温均值高0.6℃, 而树干温度比气温均值高2.1℃. 高温胁迫下, 不同园林树种的树温调节机制具有显著性差异, 依据树温调节的反应特征, 分为上升型、维持型和下降型3个类型. 其中, 单叶面积和比叶面积较大、叶片厚度较轻薄的树种, 其树冠温度相对较低, 且叶片具有较高的生理水平, 降温效果相对较强, 可作为调节小气候树种优选的参考依据.

关键词: 园林树种, 高温胁迫, 树木温度, 树冠温度, 小气候调节

Abstract:

We have investigated the correlations between tree temperature and leaf physiological variables (net photosynthetic rate, respiration rate, and stomatal conductance) and functional traits (leaf area, leaf thickness, specific leaf weight and specific leaf area) by measuring tree temperatures using infrared thermal imager in Shanghai Chenshan Botanical Garden taking 37 tree species as sample. In general, the average temperature difference between the crown and the air is 0.6℃, while the average temperature difference between the trunk and the air is 2.1℃. Under high temperature stress, the temperature regulation mechanisms of different landscape tree species have significant differences. According to the regulation shifts of the tree temperature in response to high-temperature stress, tree species can be divided into 3 types, i.e., rising type, maintenance type, and descending type. Tree species with larger single-leaf areas, specific leaf areas, and thinner leaf thickness have relatively lower crown temperatures and higher physiological levels of leaves, resulting in relatively better cooling effects. This can be used as a reference for selecting suitable tree species for regulating microclimate.

Key words: landscape tree species, high temperature stress, tree temperature, crown temperature, microclimate regulation
