太陽光電開發對鹽田濕地生態系統服務影響之評估
Assessment of Solar Development on Ecosystem Services of Salt Pan Wetland
摘要
布袋廢曬鹽田濕地位於嘉義西南沿海地區，原屬於鹽業用地。2001年鹽田廢曬後，因其地理條件，成為許多野生動物的重要棲地。布袋舊五區、八區與九區鹽場除豐富的濕地生態外，亦提供洪水調節、水資源供應、水質淨化等多元的生態系統服務。本研究生態系統服務評估，採用定性或定量狀態指標（state indicators）搭配快速評估生態系統服務（Rapid Assessment of Wetland Ecosystem Services, RAWES）方法，其中淡水供應、水質淨化、養份循環、土壤形成與棲息地服務透過生態系統服務與權衡之整合型量化模式（Integrated Valuation of Ecosystem Services and Tradeoffs, InVEST）進行模擬，整合各評估工具之優缺，綜合評估光電開發下布袋廢曬鹽田生態系統服務的衝擊。指標評估與模擬成果均顯示，光電開發衝擊以八區鹽田光電開發區域影響最大，其使淡水供應、水質淨化、養份循環、棲息地服務供應能力降低。本研究結果說明，不同光電開發工法與開發選址，對於生態系統服務會產生不同程度的負面衝擊。因此，於鹽田濕地利用與管理中，需將生態系統服務納入管理規劃考量，以利決策進行及生態系統服務的永續。

Budai salt pans are located in the coastal area of Chiayi County in Southwestern Taiwan. They were originally used for the salt industry. Due to the geographical and ecological conditions, the salt pans have become an important habitat for wildlife after the salt industry was ceased. In addition, Budai salt pans also provide diverse ecosystem services such as flood regulation, water supply, and water purification. However, salt pans in Taiwan have become the target of solar development proposals due to the national green energy policy since 2016. Solar development may degrade habitats and also affect ecosystem services. This study used the Rapid Assessment of Wetland Ecosystem Services (RAWES) method and state indicators to evaluate the impacts on ecosystem services due to solar development. Four ecosystem services, i.e. provision of water, water purification, nutrient cycling, soil formation and provision of habitat, were simulated through the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST). Results showed that the 8^(th) salt pan has experienced the greatest impact from solar development. The study further suggests in the utilization and management of salt pans, it is necessary to consider ecosystem services to help decision-making and wetland management.
