Based on Principal Component Analysis (PCA) for remote sensing image, a new method was applied into identifying the spatio-temporal distribution of sea reclamation quickly and exactly. Taking Xiamen City as an example, the combinations of Remote Sensing Images, 1993 and 1996, 1996 and 1998, 1998 and 2001, 2001 and 2003, and 2003 and 2006, were identified by PCA approach for the distribution of sea reclamation in the above five periods. In order to study the driving factors of sea reclamation at different development stages of Xiamen City, several indicators such as population, throughput of sea ports, gross industrial output value, etc. were chosen into the regress equation of the driving forces. As a result, the policy of city development, rapid industrialization and rapid increase of population are the main driving factors of sea reclamation in Xiamen City. Consequently, Strategy Environmental Impact Assessment of urban policy, Sea Area Utilization Demonstration and Payment were advised for the government to governing the sea reclamation activities.
