摘要

Urbanization is a global phenomenon and expanding gradually into rural areas, creating transportation problems, consumption of resources, and destruction of open spaces. Changes to our land are another irreversible impact caused by urbanization, affecting our environment and landscape, and causing an impact to the ecological system that cannot be overlooked. A simulation model is built in this study according to the characteristics of spatial changes of the study area as well as the CA-Markov theory. The impact factors for spatial changes in the study area are investigated and identified in the model. Then, a potential case of spatial changes in the study area is presented through quantitative results to investigate how the setup for the model structure affects the results. Finally, the landscape metrics is used for calculation and analysis to review the development of the study area through landscape ecology theory. Overall, the CA-Markov model is effective in simulating and predicting spatial changes. The results complemented by landscape metrics analysis are proven to be able to provide more information to interpret the results of spatial change and evaluate the ecological quality.
