This study quantitatively analyzed the seasonal dynamics of urban heat island (UHI) in Xiamen City, using Landsat TM/ETM+ thermal images acquired on 5 different dates in the year 2002. Landscape metrics were utilized to quantify the changes, including PLAND, PD, CA, NP, P-UHI, NP-UHI, TA-UHI, PD-UHI etc. Results showed that, August UHI was spatially intensive in not only total area, but also the extent...
Urbanization, the conversion of other types of land to uses associated with growth of populations and economy, is a main type of land use and land cover change in human history. In recent 30 years, urban growth has been speeded up, and extreme stress to the environment has occurred in China. Based on the Defense Meteorological Satellite Program's Operational Linescan System (DMSP/OLS) stable nighttime...
Thermal-infrared images of Landsat Enhanced Thematic Mapper Plus (ETM+) in 1999 was used to retrieve the land surface temperature (LST) of urban and surrounding area of Beijing, The urban heat island ratio index (URI) was selected as the indicator to estimate spatial characteristic of land surface temperature. The paper quantitatively analyzed the spatial characteristic of LST by calculating URI of...
