In the paper, we firstly acknowledge the characteristic of rainfall kinetic energy and runoff energy, current state and the development of erosion dynamic process by consulting a large number of domestic and foreign literature datum. on the basic, we systemically coordinated the eroded datum of runoff plots of soil and water conservation stations at xifeng, tianshui, suide, and chunhua et al
本文首先在查閱了大量國內外文獻資料,全面了解降雨動能與徑流能量的特性及侵蝕動力過程等方面的研究現狀及最新進展的基礎上,系統整理了西峰、天水、綏德及淳化泥河溝等水土保持試驗站的徑流場侵蝕資料。First, erosion resulting from exce ive deforestation in the u er reaches of the river and, second, heavy silting which raised the riverbed in the main cha el
第一,過度砍伐引起的河流上游的侵蝕,第二,嚴重的泥沙淤積抬高了主幹道的河床。First, erosion resulting from excessive deforestation in the upper reaches of the river and, second, heavy silting which raised the riverbed in the main channel
第一,過度砍伐引起的河流上游的侵蝕,第二,嚴重的泥沙淤積抬高了主幹道的河床。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。Two major factors contributed to devastating summer flooding along the yangtze river and its tributaries. first, erosion resulting from excessive deforestation in the upper reaches of the river and, second, heavy silting which raised the riverbed in the main channel
兩個主要因素導致了夏季長江及其支流的特大洪水。第一,過度砍伐引起的河流上游的侵蝕,第二,嚴重的泥沙淤積抬高了主幹道的河床。Therefore, nowadays major problem is how to reduce the slope cultivated land ' s soil erosion and sediment concentration transporting to three gorges reservoir in order to prolong the three gorges engineering ' s use time and protect the safety of the middle and lower reaches channel of yangtze river
因此當前的主要問題是如何臧輕坡耕地土壤侵蝕,減少進入三峽庫區的泥沙量,延長三峽工程的運轉時間,保障長江中下遊河道的安全。另外,按土壤平均厚度78 。分享友人
