For this pur- pose, conventional landscape indices are commonly used for quantitative analysis of urban landscape patterns. However, these land- scape indices only reflect information for one particular temporal phase of landscape patterns. This paper studies and quantifies the dynamic changes of urban landscape from 1993 to 2006 in Changsha-Zhuzhou-Xiangtan metropolitan areas in Hunan province of China using landscape expansion index (LEI), which contains information of the formation processes of landscape patterns. The re- sults indicate that there are three types of urban expansions: infilling, edge-expansion and outlying in the study area. The change of proportion of the three urban expansion types reveals that urban expansion patterns have changed from a messy, dispersed early de- velopment phase to more compact and reasonable layout from 1993 to 2006. Moreover, the urban expansion modes varied in differ- ent periods. From 1993 to 1996, the edge-expansion and outlying were the main types of urban expansion forms, indicating an early stage of rapid urban developments. Comparing with the edge-expansion, the outlying expansion increased rapidly in this period, which indicates urban development is messy and dispersion. Overall, the edge-expansion was the major type of urban expansion form during the study period with outlying as the second and rapidly-increasing major form of expansion prior to 1998, which indi- cates urbanization is in the early stage of rapid urban developments, and infilling as the second and rapidly-increasing major form of expansion after 1998. 1. INTRODUCTION Since the 20" century, urbanization has been accelerated global- ly. With ongoing urbanization, a large population is inclined to concentrate in urban areas. It is estimated that more than 50% of the world’s population lives in urban areas and the projected proportion of urban population will reach 69.6% by 2050, with urban growth concentrated in Africa and Asia (UN Millennium Project, 2005; UNFPA, 2007). As the largest developing coun- try in the world, China has experienced unprecedented econom- ic growth and rapid urbanization since 1980s. Its urban popula- tion has rapidly increased. The projected proportion of urban population will reach 75% by 2050, more that the world’s pro- jected increase. As the economic development policies are being implemented in Central China, e.g., the Changsha-Zhuzhou-Xiangtan metro- politan areas in Hunan province. China has been experiencing significant growth in both population size and urban area. Rapid urbanization and accelerated urban expansion have converted natural landscape to largely impervious land use patterns. These landscape pattern changes associated with urbanization are im- portant factors that contribute to ecological and climatic chang- es at local, regional, and global levels. Therefore, quantitative information about urban expansion types and processes and its explicit expression are of great interest to diverse studies and applications such as urban planning, water and land resource management, and climate change research, among others. As a result, it is important to quantitatively reveal urban expansion forms for understanding the regional urbanization process, con- trolling and planning future development of Changsha- Zhuzhou-Xiangtan metropolitan areas. The urban land use change is commonly described as either a change of urban extent or the rate of urban land change. The ex- tent and rate of urban expansion provide indications of the ag- gregate size of cities and the rate at which non-urban land is converted to urban uses (Seto et al., 2002). However, aggregate growth rates and extent give limited information about spatial patterns of urbanization. In order to quantify and describe changes in urban land-use patterns beyond extent and growth rates, landscape indices have been applied to urban morphology (Luck and Wu, 2002; Herold et al., 2003; Seto et al., 2005). Although these indices have been used to conduct empirical analyses of landscape patterns, they are generally focused on simple analysis and description of the geometric features of a landscape patch or pattern, while neglecting information on dy- namic changes of landscape patterns (Liu et al., 2009). In order to describe urban expansion forms quantitatively, Wilson et al. (2003) proposed a moving window method to quantify three ur- ban growth types according to the percentage of land cover types. Xu et al. (2007) distinguished different urban growth types using the ratio between the length of common edge and patch perimeter. Liu et al. (2009) developed a quantitative method to identify and visualize different types of urban growth. The core area of Changsha-Zhuzhou-Xiangtan metropolitan in Hunan, China includes the City of Changsha and its surround- ing areas. The total area is about 1428.99 km? and is the key center of economy, culture, manufacturing and transportation of
