Measurement of Urban Sprawl and Urban Pattern Using Geoprocessing Method
Analyzing spatio-temporal characteristics of land use is essential for understanding ecological consequences of urbanization. More importantly, such analyses can provide basic information for sustainable management of land resources. The East Pearl River Delta (EPRD) in southern China, which has experienced a rapid urbanization process from 1979 to 200S, was taken as a study region to analyze the spatio-temporal dynamics of urban land use and landscape patterns. A land use map with all of its land uses classified into 4 types which was generated based on Landsat images, together with local basic land-use information layers, were used to study the regions urban land use pattern. A set of landscape metrics were selected to quantify the landscape pattern changes in EPRD. The analysis showed that the urban area increased dramatically during this study period, meanwhile the urban patterns changed conspicuously. This study indicated that urban landscape configuration can give us a clear view of urbanization process over a long-time span, and the studied understandings on the relationship between urban sprawl and urban pattern could be meaningful to other planners.
