A Comparative Study On Spatial Structure Characteristics Of Urban Construction Land In Fujian And Taiwan Provinces

Forming and development of the urban concentrated area, is the importantcharacteristic of the modern urbanization process, it is the important trend of regionaleconomic development too. The research about the urban concentrated area has arousedthe attention from domestic and international numerous scholars. Push into economicglobalization and marketization worldwide, the competition among the country, areaembodies a concentrated reflection of the competition taking key city as central urbansystem. A comparative study of urban land use evolvement between Fujian and Taiwanprovinces could be a good case for the study because their physical proximity and theirhistorical and cultural similarity except for their different economic developmentphases.The study extracted urban construction land spatial information by integrating TMand ASTER images through RS and GIS technology, set up the database of urbanconstruction land spatial information and social economic development. Based on spatialautocorrelation, rank-size rule and fraetal theory methods, the urban construction landstructural characteristic was study in Fujian and Taiwan provinces.The result indicated that: (1) In Fujian and Taiwan provinces, urban constructionland high density districts gather, distributing in southeast coastal area of Fujian and westplain area of Taiwan mainly, and Taiwan gathers the intensity higher than Fujian; (2) Thedistribution of Fujian and Taiwan city size expressed by urban built-up area accords withrank - size rule, but urban system than simple overall small, the meditun and small gradeof cities is not enough for the development, and the land used for proportion of city largein scale of Fujian Province is well below Taiwan Province; (3) Urban construction landpatch has statistical self-similarity in Fujian and Taiwan provinces, and the spatial featureof construction land is mainly influenced by nature and humanity factors, especially by theinfluence of terrain and traffic; (4) From 1998 to 2004, the economic development phases ofFuzhou and Taibei city were different, and their types of urban land expansion weredifferent too. The type of urban land expansion belonged to the 'extension' type inFuzhou City, while the 'filling' type in Taibei City.
