As urbanization picks up speed, great changes have taken place in the Urban Landscape Pattern (ULP), which in turn causes variation in urban climate. The Heat Island Effect (HIE), a prominent feature of the changing urban climate, poses a huge threat to our life and health. Starting with HIE and with the aid of geographic information system (GIS) and remote sensing (RS), this paper studies the remote sensing images of Beijing from 1995 to 2015, which were captured by Landsat Thematic Mapper (TM) and infrared technology. Specifically, the author analyzed the evolution laws of the ULP and the HIE in Beijing, discussed the relationship between the two factors, and disclosed the controlling effect of the ULP on the HIE. The results show that: the accelerated urbanization has fragmented the landscapes in Beijing dramatically; the HIE can be alleviated by increasing the greenery coverage, reducing the spacing between green lands, and enhancing their density. Finally, several suggestions were put forward to construct a secure and ecological ULP in Beijing from the angle of adjusting the green land landscape pattern. This research sheds new light on the relationship between the ULP and the HIE and lays a basis for the planning and construction of eco-cities. [ABSTRACT FROM AUTHOR]
