摘要:

本文綜合使用觀測(cè)數(shù)據(jù)、遙感數(shù)據(jù)以及WRF-LES模式研究了射陽(yáng)港經(jīng)濟(jì)開發(fā)區(qū)的熱島現(xiàn)象。觀測(cè)數(shù)據(jù)表明：2014年以后，射陽(yáng)港經(jīng)濟(jì)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(duì)遙感數(shù)據(jù)進(jìn)一步分析發(fā)現(xiàn)，2013—2022年，由于城市建筑面積的擴(kuò)大、綠化面積的減小，射陽(yáng)開發(fā)區(qū)的熱島效應(yīng)隨著時(shí)間的變化得到了增強(qiáng)。最后基于WRF-LES模式輸出結(jié)果，分析了射陽(yáng)開發(fā)區(qū)下墊面和周邊農(nóng)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(nóng)田下墊面，其他季節(jié)溫度差別不大。秋季是射陽(yáng)港經(jīng)濟(jì)開發(fā)區(qū)城市熱島現(xiàn)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.
