An integrated remote sensing and GIS approach in the monitoring and evaluation of rapid urban growth for sustainable development in the Pearl River Delta, China

Abstract

The publication of the Brundtland Report in 1987 has led to worldwide concern over sustainable development. Sustainable development is particularly important to regions that are undergoing rapid economic development, such as the Pearl River Delta and other rapidly developing regions in China, Malaysia, Thailand and Asia. Geographical information systems (GIS) and remote sensing are useful tools in the formulation, implementation and monitoring of urban development in the move towards a sustainable development strategy. Since the adoption of economic reform in China in 1978, cities in the Pearl River Delta are developing very rapidly. Economic growth is around 20% a year, making it one of the highest growth areas in the world. Accompanying economic development is rapid urban growth. This paper attempts to demonstrate the application of the integration of GIS and remote sensing in urban growth management in the Pearl River Delta by using them to monitor and evaluate land development. Remote sensing techniques are used to carry out land-use change detection by using multi-temporal remote sensing data. Land-use change impact analysis is further carried out by the integration of GIS and remote sensing. © 1997 Carfax Publishing Ltd.
