氣候變遷及衍生的極端天氣已在全球各地造成不同程度(暴露度)的影響，影響人類的生活環境以及陸域與海洋生態系統也將日益劇烈。本研究自101年開始推動整合海洋、大氣、陸地、地質、海岸及生態所構成之環境系統資訊，藉由氣候變遷下不同環境領域資料加值分析工作，目前已建立指標包含氣候與空氣汙染、都市發展，海岸與山區災害指標和生物多樣性等，證實台灣周邊水溫暖化與間接造成部分經濟物種回游路徑北移現象，以及氣候變異對台灣降雨型態與乾旱指數的改變等。另以台南市為示範區，就都會熱島、農業區、山區與海岸七股濕地等受到區域氣候、生態環境等氣候變遷下環境衝擊進行環境潛勢分析，建構空間網格為基準之暴露度指標與量化地理資訊系統，以及填補缺漏資料(missing data)方法。至於示範區之關鍵議題與環境潛勢分析簡述如下: 都會與鄉村區:透過台南市土地覆蓋變遷與都市發展潛勢資料，掌握本市都市熱島效應與都市發展之互動機制及其在區域降水之影響。建立全台各乾旱事件類型(中度、嚴重、極端乾旱事件)，計算其乾旱發生次數、乾旱平均延時、乾旱平均嚴重度等之乾旱特性以及年際和年代際變化。海岸區:經由颱風所引起波高與暴潮模擬分析，推測未來颱風引起暴潮及波高變化趨勢。建立台南海岸現階段及未來潟湖沙洲消失後的安全性評估，完成沿岸現階段及近未來颱風溢流量安全低中高潛勢等級。分析海岸濕地生物多樣性變化。山區:發展曾文溪流域之山崩機率，面積與體積預測以及岩屑崩滑潛勢，並進一步推估強降雨下土砂量，分析極端降雨狀況下的山崩土石流災害暨流域地形演變。建立生態系統與生態保護區之基本圖層，搭配環境因子資料庫進行生物預測分布模式計算，分析山區生物多樣性變化。最後並以海岸帶災害與登革熱為例，套適與演練決策支援步驟之流程，以落實與協助調適科技規劃與施行。 In this 4-years project, we aim to produce useful environmental indices, the environmental potential exposure and other value-added products (i.e. mulit-discipline environment exposure index) and services in environmental system based on traditional/ untraditional data and satellite observation. A geographic information system is establishing with this value-added products to integrate this information. In addition, Tainan city was chosen to demonstrate the key issues associated multisystem interactions and are characterized into four geospatial definition: the urban, rural, mountainous area and coastal area. We try to consider appropriate regulatory measures for analyzing the possible influence of climate change on environmental system. It supposes not only to understand the future regional atmospheric environment/climate change tendency, but also to provide references and suggestions for risk reduction in Impact Evaluation Group (IEG) and Disaster Management Group (DMG): Urban and rural area: The land cover changes for Tainan in between 1986 and 2011 were observed. We defined the historical city development potential index in Tainan. The impact of urban heat island on regional precipitation was discussed. The long-term trend of the number of drought event, mean drought duration and mean drought severity in Taiwan based on SPI3 series were analyzed. Coastal area: We analyze the ocean warming and its impact on the marine ecology. The long-term trend of future wave height and storm surge off southwest coast of Taiwan was analized. The safety and environmental protection was evaluated. Mountain area: The rain-induced landslide hazard map, debris-flow hazard map and dip-slope landslide susceptibility map were produced. We collect species data base from those ecosystems which are urban ecosystem, marine ecosystem and wetland ecosystem. The data focused on the changes in species distribution and abundance of some ecological indicators that are important to specific ecosystems. Trends were analyzed and documented in a database using a GIS approach. Finally, two case studies, the environmental exposure to coastal disastaer and dengue outbreak in Taian city, were applied to implement the TaiCCAT’s supportive system for decision-making.
