| Summary: | 碩士 === 國立臺北大學 === 不動產與城鄉環境學系 === 96 === There is relative little research focused on assessing the impacts of the 921 Chi-Chi earthquake on land-use patterns, land-use changes and the determinants, although a large number of researches have conducted on the recovery process related to the 921 Chi-Chi earthquake. The major aim of this study is to investigate the characteristics of land-use changes and their determinants before and after 921 Chi-Chi earthquake by using a case study of Nantou County. The findings will provide the land-use decision maker a useful basis for evaluating land-use planning and earthquake risk management measures.
A LISA approach was applied to analyze the land-use patterns distribution before and after 921 Chi-Chi earthquake. Furthermore, the spatial statistics model was used to estimate the major factors that influence the land-use patterns. The results show that the residential, commercial and industrial uses are significant increase after 921 Chi-Chi earthquake, while the agricultural use decrease significantly. On the other hand, the findings from LISA analysis show that the changes of land-use patter are little.
In the recovery process, a large portion of structures were rebuilt in the same area where they collapsed during the earthquake hit. This factor results in the changes of land-use pattern was not significant after earthquake. It also implies that the land-use patterns after earthquake are reconstructed and extended based on the existing land uses before earthquake hit.
