The Taoyuan ponds, from 1900~1999 have decreased in area from 11.8% to 3.8%, and considering their reputation as a special local geological feature and their abilities to lower temperature and prevent flood, this project will propose an adaptation plan in the face of climate change, as a reference for future relevant projects. The vulnerability of ponds are initially assessed by 4 indexes including “function”, “temperature”, “rainfall” and “environmental development”. The results vary due to different calculations. The climate change will impact on the rainfall and temperature. Assessing the climate through the concept of frequency analysis, the amount of rain from rainstorm is relatively lower in Dayuan and Guishan districts, and highest in Xinwu district; The temperature in Dayuan, Guishan, Taoyuan, and Zhongli are relatively higher, and in Guanyin and Xinwu districts are relatively lower. With reference to the risk matrix concept, a sensitive area interpreting matrix was designed, and the results showed that ponds with higher sensitivity are distributed in areas adjacent to the Taoyuan, Ba-de, and Guishan city centers, for other administrative districts the sensitive areas are scattered. Regarding the cooling function, the ponds play a role in adjusting the temperatures of small-scaled areas’ microclimates. During the hottest and average temperatures, the temperatures of ponds and surrounding areas are approximately lower than the entire area. In terms of flood-prevention, the percentage in flood-prevention is greatest in coastal administrative districts. The administrative areas located on the hillsides, influenced by its topography, are low in quantity and smaller in size, hence the flood retention ability is lower.
