| 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TR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 TR 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. |
