世界大部分地区正在经历快速城市化。许多城郊开放空间，如公园、森林、农田和湿地，已被建筑物覆盖，导致城市和区域各级生态系统服务急剧下降。利用遥感、地理信息系统（GIS）技术和生态系统服务经济评价方法，获得了中华人民共和国常州市1991、1996、2001和2006年的景观空间结构演变，并对土地利用变化引起的生态系统服务功能变化进行了评价。研究结果表明，城市化地区持续扩大，生态系统服务减少。在2001年以前，耕地是主要的土地利用类型，占城市边界总面积的53.3%以上。2006年，耕地和建成区是主要的土地利用类型。从1991年到2006年，建筑面积增加了122%。从1991年到2001年，常州市域范围内的生态用地（耕地、森林、草原、水域）比例下降了24.1%。从观测到的变化来看，1991 - 2006年常州市生态用地提供的生态系统服务经济价值下降了19.3%，年均下降率约为1.3%。耕地转用是生态系统服务价值减少最多的原因，相当于2.398亿元人民币（折合3780万美元）。研究成果已被常州市城市规划局采用，并申报常州市城市总体规划。本研究不仅有助于改善常州的环境，但其他快速城市化的城市的研究和改善，因为城市地区的快速增长是近年来最明显的环境趋势之一。(C)2014爱思唯尔有限公司版权所有。
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.
