sediment balance
解釋
沙量平衡-
Study achievement appears as following aspects : ( 1 ) yellow river estuary gate river flow and tide flow mixed area is not keep standing deposition status, on special income water and sediment conditions, boundary conditions and oceanic power conditions, this area may on the scour status ; ( 2 ) observed from estuary sediment deposition distributing process : delta and sea offing area sediment deposition vary trend is similar, each part sediment deposition scale varies as wave shape ; ( 3 ) on estuary gate, affect the sediment deposition factors, primary factors are tide prop, the gate widens gradually, estuary gate have branches, brine induced flocculation. this paper study the estuary gate widen, estuary gate have branches to affect the river channel deposition in quantity ; ( 4 ) based on field measured data, for the first time, deduce the estuary sediment deposition and distributing regress formula which can estimate estuary different areas sediment deposition volume ; ( 5 ) this subject demonstrate the estuary delta coastline dynamic balance conception, build the relationship between the estuary income sediment with deposition land area, draw the following important conclusion : when estuary years - averaged income sediment keeps at 345 million tons, the delta coastline may on the dynamic balance status. ( 6 ) this subject firstly brings up estuary sediment optimized control conception, and has the primary study on the macroscopically optimized control conception method
研究認為： （ 1 ）黃河河口口門逕流潮汐區域並非持續保持淤積狀態，在特定的來水來沙、邊界條件和海洋動力條件下，該區域可以處于沖刷狀態； （ 2 ）從河口泥沙沉積分配的過程來看：三角洲與濱海區泥沙的沉積變化趨勢是基本一致的，各部位的泥沙沉積比例變化基本呈波動狀態，且三角洲與濱海區泥沙的沉積比例與來沙量密切相關，基本成正比關系； （ 3 ）在口門處，影響泥沙沉淤的因素主要集中在潮汐頂托、口門逐漸加寬、河口門分汊、鹽水造成絮凝等，本報告主要對口門加寬，口門西妥理工大學工程碩士專業學位論文分漢對河道淤積的影響進行了定量分析: （一扣根據實測資料首次建立了河贖流路泥沙沉積分配的回歸計算式，據此可以預估計算河口不同區域泥沙的沉淤量; 、 5 ）本項研究首次論證了河口三角洲岸線動態平衡的概念，並建立了黃河河口來沙量與造陸面積的相關關系，得出了當河口多年平均來沙量維持在3 . 45億t時其河口三角洲岸線則可能處于動態平衡狀態的重要結論; 『 6 ）本項研究首次提出了河口泥沙優化調控的概念，並對其宏觀優化調控模式進行了初步探討。 -
Analyze the yellow river estuary sediment transport and distributing affected factors, utilize the field measured data, based on the hydraulics, river hydrodynamic and statistics fundamental theory, analyze the estuary sediment transport and settling deposition regulation, yellow river estuary gate area sediment deposition mechanism and estuary delta coastline dynamic balance, and some important achievements acquired
研究報告分析了黃河河口泥沙輸移和分佈的影響因素，利用實測資料，運用水力學、河流動力學、統計學等基本理論和原理，對河口泥沙輸移及其分佈規律、黃河河口口門區域泥沙沉積機理以及河口三角洲岸線的動態平衡問題進行了分析探討，並取得了部分重要認識和進展。 -
So far as the alluvial fiver is concerned, the sediment - carrying capacity of flow and hydraulic geometry of river channel can be regulated by regulating the composition of flow rate, silt concentration and sediment ( water and sediment regulation ) during water and sediment discharge ; with which the relative balance for water and sediment discharge and the river channel evolution can be obtained
摘要沖積性河流的河床在輸水輸沙過程中，調節流量及含沙量和泥沙組成（調水調沙）可以調節河床水力幾何形態和水流挾沙力，追求水沙輸運和河床演變的相對平衡。 -
In the canal with sand moving balance and stable bed, may keep the current status ; for the sediment canal which seriously reduced discharge, may properly clean sediment ; for the seriously scoured canal, such as curved canal, should lining the canal
對于輸沙達到平衡、河床比較穩定又達到輸水能力的渠段，可保持現狀；對淤積比較嚴重又影響輸水能力的局部渠道，可進行適當疏浚清淤；對淘刷比較嚴重的彎道凹岸進行工程護砌。 -
With ecotype watershed construction for target, make good eco - environment, production development and life wealthy come true, lie the economy and environment foundation for building a well - off society ; controlling effectively the sediment entering into the yellow river to meet the country ’ s demand, ensure yellow river safe ; making the watershed as a unit, the administrative region divisions and the watershed region divisions combine together ; with comprehensive management for center, various measures can be taken ; taking water - sediment balance theory as foundation, build up the relatively constant dam system ; taking science and technology as support, plan and design check - dams scientifically, and rightly evaluate the comprehensive benefits of check - dam ; on the basis of small watershed integrated management model, carry on managements, demonstration and extension in the large demonstration area
以生態型流域建設為目標，實現生態良好、生產發展、生活富裕，為建設小康社會奠定經濟和環境基礎;以有效控制入黃泥沙為國家需求，確保黃河安瀾;以流域為單元，行政分區和流域分區相結合;以綜合整治為中心，多種措施並舉;以水沙平衡理論為基礎，建立相對穩定的壩系;以科技為支撐，科學規劃和建設淤地壩，正確評價淤地壩的綜合效益;在小流域綜合治理模式的基礎上，開展大示範區成片治理、示範及推廣。
