結冰河流
英文
ice－frozen stream-
Also to get some new conclusion of glacial lakes burst floods, in possibility study of glacial lake burst, and in qualitified study of the safety of the glacial lakes. the first character of this paper introduce the background of this paper, set the goal, content and methodlogy of the study work in this paper. the second chapter of this paper focuses on the meterological character, runoff composition character, why not correspondency of ratio of rainfall and runoff in same period to annual value for nianchu river, lasha river, niyang river and the middle reach of yalu - zangbu river
本文第一章介紹了課題的研究背景，提出了研究目標、內容和方法；第二章重點分析了年楚河、拉薩河、尼洋河和雅魯藏布江幹流中游段的氣候特徵，徑流組成特性，同期降水、徑流占年總量比例的不對應特性和原因，徑流年內年際變化規律及徑流深分佈特性，分析了天然洪水的特點和洪水參數；第三章介紹了冰川終磧湖的特點，結合已經發生潰決的冰川終磧湖的有關調查資料和考察資料，分析提出了危險冰湖判別指標和發生潰決的氣候條件、周期性特徵，提出了冰湖潰決洪水的計算途徑。The temperature of upper reach is higher than that of lower reach, therefore, the river freezes up from lower reach to upper reach and breaks up from upper reach to lower reach. secondly, inner mongolia reach lies in inland area. it is far from ocean and controlled by mongolia high - pressure
其次，內蒙段處于內陸地帶，離海洋距離遠，暖濕氣流難以到達，常為蒙古高壓控制，呈典型的大陸性氣候，年降水量少，夏季盛熱短暫，冬季嚴寒漫長，河流結冰期長達4 - 5個月，大部分為穩定封凍河段。The phenomenon that rivers freeze in high latitude and cold regions is universal
摘要高緯度寒冷地區的河流在冬季結冰是一種普遍現象。Taking ningxia - inner mongolia reach of yellow river as a study case, a ice regime forecast data warehouse is established for the datamining concerned on the basis of the analysis on the ice regime changing law and its influencing factor of the reach, and then the conceptual mathematic model and artificial neural network model for the parameter calibration of ice regime forecast are built up with gis in combination of the relevant empirical forecast models based on the principles of the hydrological flow muting, thermodynamics and ice hydraulics etc., with which the design and development of the decision support system for the ice regime forecast with the integrated functions of information inquiry, model parameter calibration, temperature forecast and ice regime forecast are preliminarily discussed
摘要以黃河寧蒙河段為例，在對河段歷史冰情變化規律及其影響因素分析的基礎上，建立冰情預報數據庫，進行數據挖掘，並以地理信息系統（ gis ）為平臺，以水文學流量演算、熱力學、冰水力學等原理為基礎，結合相關經驗預報模型，建立用實測資料進行參數率定的冰情預報概念性數學模型和人工神經網路模型，初步探討了集信息查詢、模型參數率定、氣溫預報、冰情預報等功能為一體的冰情預報決策支持系統的設計與開發。How different had this scene looked when i viewed it laid out beneath the iron sky of winter, stiffened in frost, shrouded with snow ! - when mists as chill as death wandered to the impulse of east winds along those purple peaks, and rolled down ing and holm till they blended with the frozen fog of the beck
這景色與我在冬日鐵灰色的蒼穹下，冰霜封凍積雪覆蓋時看到的情景多麼不同呀！那時候，死一般冷的霧氣被東風驅趕著，飄過紫色的山峰，滾下草地與河灘，直至與溪流上凝結的水氣融為一體。On the one hand, intra - annual distribution of runoff is extremely uneven with high concentration degree ; while on the other, the variation coefficient and annual extreme value little with weak increase tendency of annual changes of runoff volume but it is relative stable
分析結果表明：奎屯河流域徑流補給具有地帶性和多樣性特點，補給來源主要以冰川融水和雨水補給為主；年內分配極不均勻，集中程度高；年際變化相對穩定，變幅小，多年呈微弱增加趨勢。分享友人
