中文摘要	Much of the world is experiencing fast urbanization. Many pen-urban open spaces, such as parks, forest, farmland, and wetlands, have been built over, which has resulted in a steep decline of ecosystem services at the municipal and regional levels. Using remote sensing, geography information system (GIS) technology and economic evaluation method for ecosystem services, the evolution of landscape spatial structure in 1991, 1996, 2001 and 2006 of Changzhou City, People's Republic of China, was obtained and the change of ecosystem services resulted from land use change was evaluated. Study results show a continuing expansion of urbanized areas and reduction in ecosystem services. Before 2001, farmland was the main type of land use, accounting for more than 53.3% of the total area within the broadly-drawn municipal boundaries. In 2006, farmland and built-up areas were the main land-use types. The built-up area increased by 122% from 1991 to 2006. From 1991 to 2001, the proportion of ecological land (farmland, forests, grasslands, and water-covered areas) within Changzhou's municipal boundaries decreased 24.1%. Based on the observed changes, the economic value of ecosystem services provided by Changzhou's ecological land decreased by 19.3% from 1991 to 2006 and the annual decrease ratio was approximately 1.3%. Conversion of farmland to other uses was responsible for the largest reduction in the value of ecosystem services, equal to 239.8 million RMB (equivalent to USD 37.8 million). Our research results were already adopted locally by Changzhou Municipal Bureau of Urban Planning and applied for Changzhou Mater Urban Planning. The current study can contribute not only to improvements in the Changzhou environment, but to the study of and improvements to other rapidly-urbanizing cities, as the rapid growth of urban areas is one of the most pronounced environmental trends of recent times.
