    Abstract: 本論文採用FORMOSAT-2與ASTER衛星遙測影像進行地表溫度與地表覆蓋關係之研究,研究結果顯示地表溫度與常態化差異植生指標(normalized difference vegetation index, NDVI)呈現負相關、與地表不透水率、建築物及鋪面比例呈現正相關,顯示適當增加都市綠化或降低地表不透率、建築物及鋪面比例將有助於降低地表溫度,進而減緩都市熱島效應。根據本研究回歸分析解果顯示:地表溫度於春、夏季與鋪面比率及地表不透水率關係較密切;夏、秋季時則是以地表不透水率及代表綠化程度的NDVI關係較強。
    In this study, FORMOSAT-2 and Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) images are used to analyze the relationship between surface temperature and land cover. The surface temperature of Tainan City had a strong negative correlation with the Normalized Difference Vegetation Index (NDVI). Besides, the surface temperature was also strongly correlated with ratio of impervious area, ratio of structures, and ratio of pavement. Based on these analytical results indicate that reducing ratio of impervious area, structure, or pavement or increasing the greening of urban areas can reduce surface temperature and mitigate the urban heat island effect. Analytical results also indicate that surface temperature is related to ratio of impervious area and ratio of pavement in spring and summer data, and is related to ratio of impervious area and NDVI in summer and fall data.
