摘要

本研究基于1996年和2003年Landsat TM/ETM+两幅影像和一些必要的地面气象资料。本文采用地表能量平衡算法(SEBAL)提取地表蒸散发信息。提取城市热岛和城市扩张与蒸散量的关系，分析两者对这一时期城市热环境变化的相互作用。

Study on the information extraction of Evapo-transpiration and its relation with the urban heat island and urban expansion in Fuzhou City with its surrounding areas of SE China

This study was based on two Landsat TM/ETM+ images acquired in 1996 and 2003 respectively and some necessary ground-based meteorological data. The surface energy balance algorithm for land (SEBAL) has been used in this thesis to extract the information of evapotranspiration. The urban heat island and urban expansion of the area were also extracted and related to the information of evapotranspiration to see their interaction for the urban heat environmental changes during this period.
