In Taiwan, the ponds which are mostly distributed on tablelands in the north areas are the special landscapes established for the water diversion and agricultural irrigation in the past. They provide beneficial functions to local environments and ecology under extreme climate. However, with the relocations of urban development centers, the urban expansions focusing on land developments leads the land-uses changes of ponds. Land uses are modes constructed by the interactions of manual activities and natural environmental factors, and the land-use changes are caused by the multiple interlacements of environmental external driving forces. Through the investigations of the external driving forces and the influence ways, the early analysis and to predictions of land-use changes will provide the references for environmental managements and plans. The contributions are more essential to Taoyuan areas with many ponds and rapid development especially. Based on the research achievements of coast environmental land-use changes, the research establishes the environmental external driving factor systems. Then it applies the DPSIR model to explore the land-use modes driving the changes of ponds, inducts the categories of land-use changes, and investigates the causality between them. Exploring how the ponds disappear and finding the factors will contribute to not only the environmental protection and ecological system maintenance, but also the adaption for climate change. The research results will provide the reference for land resource plans and developments by simulating the land-use changes of ponds.
