    摘要:

    本文综合使用观测数据、遥感数据以及WRF-LES模式研究了射阳港经济开发区的热岛现象。观测数据表明:2014年以后,射阳港经济开发区温度持续升高,但由于地理位置临海,升高幅度没有周边地区大。通过对遥感数据进一步分析发现,2013—2022年,由于城市建筑面积的扩大、绿化面积的减小,射阳开发区的热岛效应随着时间的变化得到了增强。最后基于WRF-LES模式输出结果,分析了射阳开发区下垫面和周边农田的能量变化情况。感热通量是白天温度的主要来源,土壤热通量主要影响夜间温度。因此,春秋季白天以及秋季晚上,开发区下垫面温度明显高于农田下垫面,其他季节温度差别不大。秋季是射阳港经济开发区城市热岛现象最明显的月份。

    Abstract:

    The heat island phenomenon of Sheyang port economic development zone was studied by using observational data, remote sensing data and WRF-LES model.Observation data shows that since 2014, the temperature in Sheyang port economic development zone has continued to rise, but due to its geographical location, the increase is not as strong as in the surrounding areas.Through further analysis on remote sensing data, it was found that from 2013 to 2022, due to the expansion of urban building area and the reduction of green area, the heat island effect of Sheyang development zone has been enhanced over time.Finally, based on the output results of the WRF-LES model, the energy changes of the underlying surface and surrounding farmland in the Sheyang development zone were analyzed. Sensible heat flux is the main source of daytime temperature, and soil heat flux mainly affects nighttime temperature. Therefore, during the daytime and evening of the spring and autumn seasons, the temperature of the underlying surface in the development zone is significantly higher than that of the farmland, and the temperature difference in other seasons is not significant. Autumn is the month with the most obvious urban heat island phenomenon in the Sheyang port economic development zone.
