臺灣地區因山高地陡，加上長延時及高強度之降雨型態，造成降下之雨量大多成為地表逕流，因此必須利用各種方式來貯蓄水源，以供應旱季用水；而在面對全球氣候變遷可能帶來洪、旱加劇的極端氣候現象，滯(蓄)洪設施的設置，勢必成為日後治水的對策之一，但新設滯(蓄)洪設施因受限於經費籌措與用地取得的問題，如何以有限的經費成就最大水源涵養效益實為當今水資源管理之重要課題。
水源涵養乃是利用不同截蓄保水設施，來增加水資源的再利用，而其中最簡單的方式即是利用天然窪地來涵養水源，除可在平時貯蓄水源外，亦可在颱風、豪雨等強降雨事件發生時，發揮調節洪峰流量與沉砂滯洪的功用；且天然窪地常具有豐富之景觀生態，若能進一步結合農村社區資源，將可營造為防災、保育、休閒遊憩環境及生物多樣性等多功能之埤塘。
南投縣名間鄉炭寮村計有55個窪蓄區位，有道路通過者僅有2處，本研究遴選其中體積與集水面積較大之漥蓄區位，進行水域空間之規劃營造，藉由綠建築設計之基地保水理論配置透水鋪面，具體量化配置前後基地保水量，得規劃配置前保水指標為0.569，低於法規標準值之0.68，而規劃配置後為0.722，符合法規標準。本埤塘經規劃後，所創造出兼顧生產、生活、與生態的埤塘活化效益，俾供農村社區道路邊坡埤塘空間營造之參考。With the properties of steep terrain in mountainous area, long duration and high intensity of rainfall, which results in abundant surface runoff in Taiwan. Therefore, several kinds of water storage facilities should be taken to supply water resources in the drought seasons. In addition, global climate change results in accelerating the extreme climate is increasing the probability of drought and/or floods in the future. Consequently, the trend of increasing retention facilities is a necessary for the strategies of water resources management.
Water resources storage is to increase the utilization of water resources using different interception and water-holding facilities. The simplest way to conserve water resources is using topographic depressions in a watershed because it can be as runoff storages for the use of irrigation in drought seasons, and also can decrease the peak flow of storm in typhoon seasons.
There are in total of 55 topographic depressions in Tan-Liao Rural Community. Among them, there are 2 depressions site adjacent to the road. In this study, we choose the one which has larger volume and catchment area to plan and construct for the use of water space. The water storage index (λ) is 0.569 and 0.722 calculated from the pre- and post-planning respectively using green building design theory, the post-planning can reach the standard λc=0.68. This study can be as a reference of space construction for the pond adjacent to the road in the rural communities.摘要...........................I
