中文摘要 | 地層下陷是水土資源保育與公共設施安全的重要課題,其形成原因複雜,不易掌握。由於雲林為台灣地層下陷之嚴重區域,公共用水長期大量取用地下水,因此了解公共用水抽取地下水對地層下陷之影響,有助於提供解決方案,減緩雲林地區之地層下陷,並達到地下水資源永續利用之目標。本文探討雲林地區地層下陷形成原因,使用現地資料,藉由數值模式模擬,提供該區減抽公共用水地下水之可行方案及其可能之改善效益。 |
英文摘要 | Subsidence is an important issue in soil and water conservation and also in the safety of infrastructure. The causes of subsidence are complicated and are difficult to handle. Yunlin is one of the most serious subsidence areas in Taiwan. The long-term groundwater exploitation for public water supply in this area has been blamed for the subsidence. However, the degree of the influence by groundwater pumping is unclear. Understanding the mechanism helps to mitigate the subsidence. In this paper, we collect field data and utilize numerical modeling to simulate the subsidence. Scenarios to reduce pumping at different layers were proposed. Their effectiveness on the reduction of subsidence was explored. |
