A Study on the Land-Cover Change Indicators of Taipei Metropolitan Areas

The traditional research of land cover/land use change sets focus on the spatial unit of parcel or grid for analysis and simulation. Since the change of individual land use would be affected by the surrounding land uses, there is another possibility to explore the land use change in terms of spatial pattern. The paper applies indicators of landscape metrics to analyze pattern characteristics of urban structure, and cluster analysis and discriminant analysis to identify the type of spatial pattern. This paper attempts to analyze land use pattern and its changes by metric analysis with patch-corridor-matrix structure. The process includes three phases. The first phase is to explore categories of land use pattern and attributes by cluster analysis. The second phase is to analyze pattern changes with different periods and to identify properties of pattern changes in the whole system. The final phase is to classify the pattern changes and to look for the relation between different patterns. Through analysis of pattern changes, it would be helpful to realize urban development relative to landscape metrics and to offer new thinking other than traditional urban development thinking
