碩士 === 國立成功大學 === 都市計劃學系碩博士班 === 101 === The central concept of compact city is about connecting different land use to form a multi-core corridor of living functions by efficient public transportation networks; in other words, land use is the basis of urban spatial structure of compact city. Therefore, the issues that might exist in land use activities must be considered while studying compact spatial structure. To land use activities, Land-use patterns are multi-scales as the distribution of land use activities in space is hierarchical. Ignoring this cluster patterns between different scales of land use will reduce the capabilities of description for urban spatial structure. The article takes Taichung City as study area and the land-use plots are used as analytic units. Attempting to explore geographic phenomena of land use patterns by geographical spatial data mining based on disaggregated unit of land parcel, the author applies cluster analysis and GAM point spatial pattern analysis in this research. Then the author improves the measurement using the technology of GIS spatial analysis to provide more specific insights about how city is being compacted, and thus the indices of compactness can be re-designed. And the final outcome of empirical study is visualized via GIS software to represent the spatial structure of compactness. The results indicate that different hierarchy of land use will affect the distribution of compactness core in space. We find out that the main compact center in global scale is located in West-Central District and North District, and in local scale there is no specific core in study area. And by a further analysis of the characteristics of compactness, we find out that there is a main pattern in the development of Taichung City, that is, the downtown city is expanding from old areas to new towns.
