摘要:

本文綜合使用觀測數據、遙感數據以及WRF-LES模式研究了射陽港經濟開發(fā)區(qū)的熱島現象。觀測數據表明：2014年以后，射陽港經濟開發(fā)區(qū)溫度持續(xù)升高，但由于地理位置臨海，升高幅度沒有周邊地區(qū)大。通過對遙感數據進一步分析發(fā)現，2013—2022年，由于城市建筑面積的擴大、綠化面積的減小，射陽開發(fā)區(qū)的熱島效應隨著時間的變化得到了增強。最后基于WRF-LES模式輸出結果，分析了射陽開發(fā)區(qū)下墊面和周邊農田的能量變化情況。感熱通量是白天溫度的主要來源，土壤熱通量主要影響夜間溫度。因此，春秋季白天以及秋季晚上，開發(fā)區(qū)下墊面溫度明顯高于農田下墊面，其他季節(jié)溫度差別不大。秋季是射陽港經濟開發(fā)區(qū)城市熱島現象最明顯的月份。

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.
