摘　　要：以三峡库区城市——重庆市万州区为研究对象,对不同时相的遥感影像进行地表温度反演,选取景观格局指数分析热力景观格局动态变化,并进行驱动力分析.结果表明:2003—2009年,万州区热岛、强热岛区面积逐年增长,热岛区为景观基质;强绿岛区面积逐年增长.景观最大斑块指数、连通性指数、聚集度指数均逐年降低,景观破碎化程度增大;景观丰富度保持不变趋势,Shannon指数及景观均匀度指数逐年增加,景观多样性、异质性增加.Using the different phases Landsat TM images, the distribution maps of the land surface temperature in Wanzhou district, Chongqing were figured out, and the dynamic changes of urban thermal landscape pattern are analyzed. Following the landscape indices in this paper, and the driving force are analyzed. The results showed that：from 2003 to 2009,the heat island, strong heat island area in Wanzhou district increased year by year, and the heat island is landscape matrix. The strong green island area increased with the impoundment of the Three Gorges. The largest patch index, connectivity index, aggregation index decreased year by year, and degree of landscape fragmentation increased. While landscape richness index remain unchanged Shannon index and landscape evenness index increased year by year, also landscape diversity and heterogeneity increased.
