高雄市暴潮衝擊評估與調適策略

高雄市的發展不僅是重工業為主，因良好地理位置與地形條件提供發達海運所需要素，使高雄港亦是優良的國際港埠，因此諸多工廠依傍在高雄港左右以利進出口貿易，地勢上而言，市區近沿海區域大多為沖積平原地形，這廣大的平原也正適於都市蓬勃發展，但面對極端氣候、降雨變遷、溫度變遷、海面上升四大氣候變遷因子，原先的優勢也將面臨威脅。由於臺灣位處西太平洋颱風路徑之要衝，每年平均約有3.75次颱風侵襲臺灣地區，暖化效應及海洋氣候變遷的影響，全球海水位的抬昇以及颱風頻繁的發生等問題已加劇影響到我們所生存的環境，尤其海平面的逐年上升使得暴潮可能引致的災害不容忽視。本研究將以地文性淹水模式配合降雨型態、暴潮偏差重現期與水系量測等資料進行不同情境之溢淹模擬，同時參考沿海地區人口、土地利用、經濟發展分布情形進行沿海區域脆弱度分析以擬定防減災調適策略。

The development of Kaohsiung is not only based on heavy industry, but also good location and topography. These conditions provide the elements needed to develop maritime transport. These conditions provide the elements needed to develop maritime transport. Therefore, many factories are relying on the Kaohsiung harbor to facilitate trade. From the topography, urban coastal areas are mostly alluvial plain terrain, the vast plain is also suitable for urban flourish. However, in the face of the four major climate change factors, including extreme weather, rainfall changes, temperature changes and sea level rise, coastal cities will be threatened by the climate. An average of about 3.75 typhoons hit Taiwan each year. The rise of the global sea level and the frequent occurrence of typhoons have gradually affected the environment in which we live. In particular, the rise of sea level year by year makes the possible disaster caused by the storm surge not negligible. In this study, we will take PI model based on the combination of rainfall patterns, the recurrence of storm surge and water system measurements to simulate different scenarios. The simulation results are also used to analyze the vulnerability of the coastal areas, make reference to the population distribution, land use and economic development in coastal areas, and further formulate mitigation strategies.
