The paper analyzes and summarizes the following laws of distinctive sediment yield produced in storm floods of the region based on predecessors ' study : storm is the main dynamic force of erosive sediment yield and storm, flood and sediment exist an inevitable relation ; the flood occurring time is concentrated with high peaks and huge volume, suddenly rising and suddenly falling and has decisive influence to the formation of a major flood peak in the middle yellow river ; the main reasons of concentrated coarse sediment of the river is severe erosive sediment yield, strong sediment transporting capacity and high sediment concentration ; the important influence of frequent or continued storm floods happened in he - long reach especially in coarse sediment concentrated region to the sediment transport of the yellow river and ; along with the increase of harnessing, regional flood trend is becoming smaller but the variation of sediment quantity is not obvious and the reaction of peak discharge and flood runoff of majority tributaries are not sensitive, showing that a general and normal engineering works can not effectively control regional major floods especially the sediment of an extraordinary flood
摘要在前人研究的基礎上分析總結了該區特有的暴雨洪水產沙規律:暴雨是侵蝕產沙的主要動力,暴雨、洪水、泥沙之間存在著必然的關系;洪水發生時間集中,峰高量大,暴漲暴落,對黃河中游大洪峰的形成具有決定性影響;侵蝕產沙強烈而粗泥沙集中,輸沙能力強,洪水含沙量高,是黃河粗泥沙的集中來源地;河龍區間特別是粗泥沙集中來源區頻繁或連續的暴雨洪水對黃河輸沙有重要影響;隨著治理水平的提高,區域洪水有減小趨勢,但泥沙量變化不明顯,大部分支流的洪峰流量、洪水含水量反應不敏感,說明一般規模和水平的治理工程還不能有效控制區域大洪水特別是特大洪水的泥沙。On the basis of previous studies, the paper presents a comprehensive review and summary on the influence of sediment to water quality in the yellow river, highlighting four issues : 1 the influence of the sediment on pollutant behavier, 2 the relationship between sediment - associated natural organic matter and water quality parameters of oxygen - consuming organic pollutants and its influence on the assessment of the water quality in the yellow river, 3 the relationship between the heavy metal background values of the sediment and the water quality parameters of the heavy metals and its influence on the assessment of the pollution of the yellow river, 4 the influence of sediment ? ? containing much carbonates in the yellow river on the water quality and the monitoring of the water quality
黃河是世界上罕見的多泥沙河流,泥沙與水相互作用對黃河水質產生顯著影響。根據以往研究工作,對黃河泥沙與水質的關系問題作全面的總結評述和展望,著重於4個問題: 1黃河泥沙對污染物行為的影響2黃河泥沙中的天然有機質與黃河耗氧有機物水質參數的關系和對污染評價的影響3黃河泥沙中的本底量重金屬與黃河重金屬水質參數的關系和對污染評價的影響4黃河泥沙中的碳酸鹽對水質和對水質監測研究的影響。On the basis of previous studies, the paper presents a comprehensive review and summary on the influence of sediment to water quality in the yellow river, highlighting four issues : 1 the influence of the sediment on pollutant behavier, 2 the relationship between sediment - associated natural organic matter and water quality parameters of oxygen - consuming organic pollutants and its influence on the assessment of the water quality in the yellow river, 3 the relationship between the heavy metal background values of the sediment and the water quality parameters of the heavy metals and its influence on the assessment of the pollution of the yellow river, 4 the influence of sedimentcontaining much carbonates in the yellow river on the water quality and the monitoring of the water quality

結果表明,近期隨著水沙條件、潼關高程等的變化及工農業的發展,渭河的水環境發生了巨大變化,表現在年水量及汛期水量銳減;大流量級水流出現次數減少,水量減少幅度大;年輸沙量總體減少,河水含沙量增大,泥沙淤積嚴重;河道向擺動型發展,河道萎縮,河勢惡化;大洪水發生的次數顯著減少,高含沙小洪水明顯增多;同流量洪水位普遍抬高,洪災發生次數增加,洪災加重;水質污染極為嚴重。分享友人
