The Changes of Farmland by Using Spatial Cluster on the Case of BeiNan Township in Taiwan

The main objectives of this study are, (1) to investigate the influences of farmland policies on land use patterns and, (2) to examine the changes and statuses of land transactions and farmhouse construction projects and determine the influence of changes in the restrictions of farmland use and farmhouse construction on the trends of farmland transactions and transfers and the locations of farmhouse constructions projects, thereby validating the development trends of farmland and farmhouses. Aspatial analysis was performed to examine the spatial clustering conditions and locations of farmland transactions and farmhouses in Taitung County. Regional analysis was performed by examining local indicators of spatial association (LISA). A year-over-year analysis was performed on the scope and degree of farmhouse clustering within the target area to determine farmland use patterns, distribution statuses, and the impact of annual location change on rural development in the target area. An analysis of the historical land transaction and building change data revealed that "laws and regulations" were the main factors influencing farmland transaction. The density of farmland transactions increased closer to main traffic routes. The findings of this study highlighted rural change and validated urban sprawl.
