摘要

Rapid urbanization transforms the natural landscape to anthropogenic urban land and changes surface biogeophysical characteristics. Urban growth affects the ecology of cities in a number of ways, such as eliminating and fragmenting native habitats, modifying local climate conditions, and generating anthropogenic pollutants. Urbanization has changed many landscapes throughout the world with serious ecological consequences. To understand the ecology of urban systems, it is necessary to quantify the spatial and temporal patterns of urbanization, which often requires dynamic modeling and spatial analysis. Geospatial information provided by satellite remote sensing sensors and biogeophysical field data are very useful for urban land cover dynamics and impacts analysis. This paper aims to provide a spatio-temporal analysis of urban structure for Bucharest urban area in Romania based on multi-spectral and multi-temporal satellite imagery (LANDSAT TM, ETM; IKONOS) over 1989 - 2007 period. Understanding the structure of urban cover dynamics is very important to urban management for reasons such as runoff control, urban forest planning, air quality improvement, and mitigation of global climate change. Accurate maps of urban land cover/use changes can provide critical information to better understand urban ecosystems and help improve environmental quality and human health in urban areas.
