摘要:

基于Landsat TM遥感影像第六波段对厦门市1993年和2006年填海区域的热环境进行了反演，通过相对亮温指标T_R对城市热岛的空间分布进行了描述。对比1993～2006年填海区域城市热岛分布得出：2006年与1993年相比，填海区域温度平均升高了0.55个城市热岛等级，从填海前的绿岛转变为弱热岛；填海前的水面、湿地对于城市热岛起到缓解作用，填海工程对城市热岛的形成起促进作用。

Study on urban heat island effect of sea reclamation inXiamen City

Abstract:

Based on the 2 senses of Landsat TM(6), the brightness temperature of sea reclamation area in Xiamen city in 1993 and 2006 was retrieved.Using the Comparative Brightness Temperature Index T_R describes the space distribution of Urban Heat Island. By comparing the difference between the 2 senses, the results show that: before the sea reclamation, the wetland and sea could put off the effort of UHI, however, the sea reclamation enforces the effort. Between the 12 years of 1993～2006, the UHI degree of sea reclamation area has increased 0.55, and the Green Islands has already changed into the weak Heat Islands.

Key words: sea reclamation urban heat island (UHI) remote sensing monitor
