%X 研究了三峡库区万州城市热岛演变规律及其与城市形态格局的关系.利用1996-2014年夏季Landsat TM/ETM+/OLI_TIRS系列遥感影像来反演万州地表温度，研究其热岛的时空分布及变化特征，提出组团式热岛重心扩散模式；同时提取万州中心城区土地利用类型，量化热岛效应与城市形态布局的关系，指出应提倡城市组团式的发展方式，完善各组团内的各种基础设施，减少不必要的通勤，从而最终达到降低热岛效应的目的.<br>Using the Summer Landsat TM/ETM+/OLI_TIRS remote sensing images from 1996 to 2014, retrieval of the land surface temperature of Wanzhou was made to study the spatial-temporal distribution and variation characteristics of the urban heat island, and a group-type heat island centroid diffusion model was proposed. Meanwhile, the information of land-use types of the central urban area of Wanzhou was extracted for a quantitative research of the relationship between heat island effect and urban layout. In conclusion, urban planners and decision-makers should advocate the city group development model, improve the infrastructure in each group, reduce unnecessary commuting and finally reach the aim of reducing the heat island effect
