城市公园绿地作为减缓城市热岛效应的重要手段已被广泛接受,然而由于其影响因素繁多,研究方法不一,导致其影响机制仍缺少深入研究。通过梳理当前主要的3种研究方法:地面监测研究、遥感与地理信息系统分析研究和数值模拟研究,分析其优缺点以及在不同尺度上的适宜性,认为随着数值模型计算能力和精度的提高,结合地面实测数据验证的数值模型将成为中小尺度上城市公园冷岛效应研究的主要方向,而基于遥感和地理信息系统的分析模型更适宜于景观尺度上的研究,但应加入对公园外部空间格局及局部气候的考虑,以达到提高公园生态效益、减缓城市热岛、改善城市环境的目的。
Urban park green space has been widely accepted as an important means of mitigating the urban heat island effect. However, due to its various influencing factors and different research methods, its impact mechanism is still lack of further study. By combing the current three main research methods: ground monitoring research, remote sensing and geographic information system analysis and numerical simulation research, analysis of its advantages and disadvantages as well as the suitability of different scales, that with the numerical model to improve the ability and accuracy , The numerical model verified by the measured data from the ground will become the main research direction of the cold island effect in the urban park at the small and medium scales. However, the analysis model based on remote sensing and geographic information system is more suitable for the research on the landscape scale. However, Pattern and local climate considerations, in order to achieve the goal of improving the ecological benefits of the park, reducing the urban heat island and improving the urban environment.
