近年來人口成長及都市化的增加，造成了環境污染與棲地破壞。 此外，提到，災害風險頻率會隨著生態系的退化而增加。隨著環境保護意識提高，生態防減災（Eco-DRR）與基於自然的解決方案（NBS）逐漸受到重視。生態防減災與基於自然的解決方案是以保留生態系及保護生物多樣性的方式來減緩災難風險。本研究利用生態系服務（ES）的價值與淹水的經濟損失評估生態防減災的效益。生態系服務是以生態系和其中的物種運行的過程為出發點，提供人類維持自身生命或滿足需求的福祉。研究地點位於五溝水，該地點於2012年後進行了新赤農場永久屋基地聯外排水改善工程，改變了其原生生態。在生態系服務價值方面使用InVEST模式計算出年度產水量、碳儲存含量及棲地品質，並對產水量及碳儲存含量進行價值的量化。在淹水的經濟損失評估方面使用HEC-RAS軟體對在五溝水進行二維變量流模擬，並計算洪水侵襲研究地點造成的農作物損失及房屋損失。在計算生態防減災價值方面使用了重製成本法（Replacement cost method）。基於保留原生生態系的假設，新赤農場永久屋基地聯外排水改善工程的施工成本被視為原生生態系的隱藏價值。在本研究中，生態防減災的總價值優於聯外排水改善工程的價值，這可以支持生態防減災減少災害風險的觀點。

Along with the high growth rate of urbanization and rapid population increase, the frequency and scale of disasters have increased in recent years. On the other hand, due to the environmental awareness raising, some disaster prevention projects are beginning to be strictly inspected. A project with the concept of sustainable development should consider the balance between human and nature. Ecosystem-based Disaster Risk Reduction strategy (Eco-DRR) and Nature-based Solutions (NBS) are gradually gaining attention. Eco-DRR and NBS pursue a solution to mitigate disaster risk in an ecosystem way. This study considered ecosystem services (ES) as an evaluated approach of Eco-DRR assessment. ES are the conditions and processes through which natural ecosystems, and the organisms that make them up, sustain and fulfill humanity. The study site was located in Wu Gou Shui, where the place underwent a drainage project after Typhoon Morakot. This research calculated three different ES with InVEST model, including water yields, carbon storage and habitat quality. The flooding was simulated by using HEC-RAS model. In order to calculate the value of Eco-DRR, the replacement cost method was used. In this research, the value of Eco-DRR was better than the value of drainage project, which can support the concept of Eco-DRR.
