中文摘要 | 利用有限元素法及線性規劃,本文建立安全出水量線性模式,以推估區域地下水最佳抽水量。模式應用分成兩部份,其一利用位於雲林地區之190公頃超量灌溉試驗區資料,分別測試轉換係數ω及抽水量目標係數γω對最佳值的的影響。其二針對彰化雲林平原做年安全出水量之推估,並由結果得此區域之地下水年安全抽水量已經低於地下水年補給量約1.3億噸至3.3億噸之間。 |
英文摘要 | By Combining finite element method and linear programming, a linear model on safe yield of groundwater was constructed for the estimation of optimal pumpage of regional groundwater. Applications of linear model within this paper were divided into two parts. Firstly, the effects of optimal pumpage introduced by transformation coefficient ω and cost coefficient γω of pumping term were discussed with the field data of over-irrigative region of area 195 ha. Secondly, we used linear model to estimate the annual safe yield of groundwater of region Yun-Lin and Chang-hua, and the results showed that annual safe yield of groundwater were 1.3 to 3.3 hundred million tons per year less than annual natural recharge of groundwater. |
