中文摘要:
      城市热岛效应是一种非常重要的局地气候现象,随着全球变暖和城市化快速发展,城市热岛效应受到越来越多的关注和研究。以往的研究表明人口聚集和人口数量对城市热岛效应和区域城市气候会产生显著的影响。但是,人口短期的快速迁移流动对城市气候是否存在影响以及影响的程度多大尚不清楚。本文利用世界上每年最大规模的人类迁徙——春节人口流动来探讨人口短期快速流动对国际化大都市上海城市热岛效应的影响。研究结果表明,2000~2015年上海市春节周日最高温、日均温和日最低温城市热岛强度分别为0.35℃、0.90℃和1.53℃,相对于背景场(春节前2~4周和春节后2~4周的平均值),分别低了0.16℃、0.11℃和0.15℃,相对变化分别为31.4%、10.9%和8.9%。由此可见,人口短期快速迁移流动是影响热岛效应和城市气候一个重要因素,但是人口流动对城市热岛效应的影响是复杂的,其效应与气候背景、天气状况、城市规模、城市人口流动特征及分布甚至城市烟花爆竹燃放(通过影响气溶胶、云量及废热影响城市热岛效应)等因素交织在一起,未来仍需开展进一步的深入研究。
Abstract:
      Urban heat island (UHI) is a very important local climate phenomenon. With the rapid development of global warming and urbanization, UHI effect has received more attention and research. Previous studies have shown that population aggregation and population size have a significant impact on UHI effect and regional urban climate. However, whether and to what extent the massive human migration can affect the urban climate remain unclear. The world's largest annual human migration, i.e. the population movement around the Chinese New Year (CNY), is taken as an example in the present study to investigate the effects of massive human migration on UHI during the CNY holiday for the period of 2000-2015 in Shanghai. It was found that the daily maximum (△UHⅡmax), mean (△UHⅡmean), and minimum (△UHⅡmin) surface temperature difference between urban and nearby rural stations averaged over the period 2000-2015 during the CNY week were 0.35℃, 0.90℃, and 1.53℃, respectively, which were 0.16℃ (31.4%), 0.11℃ (10.9%), and 0.15℃ (8.9%) lower than those during the background period (2-4 weeks before and 2-4 weeks after the CNY week), respectively. Our findings highlight the important role of massive human migration on urban climate based on a case study in Shanghai. Meanwhile, the results also indicate that the influences of human migration on urban climate are complex, which are often intertwined with local background climate, weather condition, city size, and the characteristics and pattern of human migration and even firework prohibition (by means of impacting the aerosols, cloud cover, and waste heat release). Therefore further studies on this issue are necessary.
