半干旱区城市广场树木形态对微气候的影响研究

植物群落是改善微气候的重要影响因素,是微气候变化的驱动力之一,它对微气候的形成、变化等进程的影响已成为当前研究的重要组成部分。以半干旱区城市呼和浩特成吉思汗广场中4种不同植物群落类型的样地和1块空地为试验地,进行风速、温度、湿度实测和ENVI-met软件模拟分析,以评估各样地对微气候的影响。研究结果表明:植物群落调节微气候具有明显的季节性差异,且与树木胸径、高度、郁闭度、叶面积指数有明显相关性;乔木高度、形状、胸径可直接影响微气候环境,25m高、心形、中等胸径的落叶乔木在夏季的降温、增湿、通风作用最明显;5m高、圆柱形、小胸径的落叶乔木在春、秋、冬3季增温、增湿、降风效果最优。揭示了广场植物群落数量属性与微气候变量之间的联系,确定了关键微气候变量在各植物群落中的变化规律,此结果可为半干旱地区广场绿色空间的植物种植设计提供参考及依据。

Manifestation of Traditional Cultures in Classical Chinese and Korean Gardens

Classical garden as a kind of comprehensive art embodies a nation's culture and spirit, and culture has a direct impact on the style of classical gardens in the same period. Traditional Chinese and Korean gardens have intimate connection with each other and have their own unique systems. Also it is no exception in culture, that is, similar traditional cultures have different manifestations in their respective classical gardens.
