This paper uses methods of GIS and RS, in particular, to interpret the remote sensing image, combined with the town level administrative division map. Thus it provides a standard method of defining the rural-urban fringe. According to this method we can define the rural-urban fringe of Wuxi in 6 periods from 1979 to 2008. Analyses show that the scope of rural-urban fringe has a positive correlation with the size of built-up urban area and the level of economic development. Referring to China's land-use classification system, the paper divides the land types in rural-urban fringe over the years. Using statistical features of GIS attributes table and the method of landscape ecology the paper researches the structure of the land-use, and the results show that the proportion of construction land rapidly increases as the scope of rural-urban fringe changes; at the same time, the proportion of plowland continues to decline. All the types of land-use tend to be fragmentated while construction land tends to integrate after 1998. This reflects that various planning endeavors take effect in control of construction land. The boundary length and the proportion of adjacent land also show that the rural-urban fringe land-use structure has changed. To sum it up, this analysis shows that the construction land has dominated the rural-urban fringe area instead of plowland.

Key words: rural-urban fringe, land use types, structure evolution, Wuxi
