圍墾堤 的英文怎麼說
中文拼音 [wéikěndī]
圍墾堤
英文
polder dyke-
The analysis indicates that the recovering rate of the salt marshes is related to the residual salt marshes area outside the seawall
分析表明鹽沼恢復的速度與圍墾以後海堤外側予留的鹽沼面積有關。Mathematical model is used to calculate and analyze water line in case of 9 kinds of flood flow levels respectively in reservoir. there are two programs including with enclose tideland for cultivation and without it in every flow level
利用數學模型分別對9個洪水流量級進行了水庫沿程水面線計算分析，每個流量級分有圍墾堤和沒有圍墾堤兩個方案。( 2 ) the water level ascending value effected by enclose tideland for cultivation dyke is reverse proportion to flows below 2000m ' / s, water level has surpassed the top of dam when flow is above 2000m3 / s, water level ascending value is declassing in the same flow level caused by enclose tideland for cultivation dyke
（ 2 ） 2000m ~ 3 s以時，圍墾堤影響的水庫水位抬高水位值隨流量增大而增大差逐漸減少，在2000m ~ 3 s以上時，水位已經超過圍墾堤堤頂，圍墾堤所引起的同級流量下水位抬高值逐漸減少。Effecting of enclose tideland for cultivation on water level in the same flow level are quantitatively analyzed, the main achievement and suggestions are given as follows : ( 1 ) the water level rise is the most which effected by enclose tideland for cultivation dyke when flow is 2000m3 / s, the max water level difference in case of enclose tideland for cultivation dyke or no arrives 0. 66 m
定量地分析了圍墾堤對同級流量下的庫水位的影響，主要成果結論及建議如下： （ 1 ） 2000m ~ 3 /時庫區圍墾堤對水庫水位抬升最大，有無圍墾堤水庫水位差最大達到0 . 66m 。Qualitative analysis on the effect of flood control and engineering safety -, seizing lots of water conservancy effective adjust storage. then making water level risen and reservoir backwater enlarged in the same flow level ? effect on beach and the buildings across river, soil salinization caused by flow from a lower to a higher place and unsmooth groundwater drainage destroy of travel resource caused by disorder enclose tideland for cultivation in reservoir silt up flood plain are given, then presents enclose tideland for cultivation dyke is important cause which water level rise in reservoir
本文從青銅峽水庫泥沙淤積入手，分析水庫泥沙淤積特性和庫區圍墾堤開發利用淤積灘地的現狀，對防洪安全及工程安全的影響、侵佔大量的有效調蓄庫容、造成同級流量下水庫水位抬升水庫回水上延、對沿岸及過河建築構成影響、因水位抬升致使庫區周邊灌區地下水排水不暢乃至倒灌而造成土地鹽堿化、對水庫庫區大量淤積灘地無序圍墾造成旅遊資源破壞等五方面影響的定性分析，提出庫區圍墾堤是水庫水位抬升的重要原因。分享友人
