【摘要】：南水北調(diào)工程的安全運行涉及到工程基礎設施安全、水量安全、水質(zhì)安全及防洪安全等方面,其中水質(zhì)安全是工程的最終目的和根本落腳點,是決定工程成敗的關(guān)鍵因素,這是由南水北調(diào)工程的性質(zhì)所決定的。為確保南水北調(diào)工程輸水水質(zhì)的安全,本文分別對南水北調(diào)東線工程和中線工程的突發(fā)性輸水水質(zhì)風險進行了評估,指出各自存在的水質(zhì)風險因素類型,并對衛(wèi)星遙感降雨信息在無地面觀測資料中小流域防洪預警中的應用進行了探討。主要研究內(nèi)容及取得的成果如下： (1)對南水北調(diào)東線工程進行了水質(zhì)風險分析,歸納總結(jié)威脅東線工程輸水水質(zhì)安全、引發(fā)突發(fā)性水污染事件的水質(zhì)風險因素類型。分析選取淮安段作為南水北調(diào)東線工程典型渠段的原因,并對其分為4種可能情景進行模擬分析,研究針對突發(fā)性水污染事件的應急調(diào)控手段和措施。 (2)對南水北調(diào)中線工程進行了水質(zhì)風險分析,歸納總結(jié)威脅中線工程輸水水質(zhì)安全、引發(fā)突發(fā)性水污染事件的水質(zhì)風險因素類型。分析選取京石段作為南水北調(diào)中線工程典型渠段的原因,并對其分為3種可能情景進行模擬分析,研究針對突發(fā)性水污染事件的應急調(diào)控手段和措施。 (3)以丹江口水庫流域為研究區(qū)域,選取2009-2012年7-9月為研究時段,利用中國氣象科學數(shù)據(jù)共享服務網(wǎng)上的地面雨量站降水資料數(shù)據(jù)集,對國家衛(wèi)星氣象中心研發(fā)的風云2D衛(wèi)星的6h降水估計產(chǎn)品PRE的精度進行了分析,分為單站點降雨量精度評估和流域面雨量對比分析。結(jié)果表明衛(wèi)星估計的精度較高,估測能力較強,能有效估測降雨量及降雨趨勢。以南水北調(diào)中線總干渠沿線河北省境內(nèi)4個中小流域為例,對將衛(wèi)星遙感降雨信息初步應用于中小流域的防洪預警中進行了探討,結(jié)果表明將衛(wèi)星遙感降雨信息應用于無地面觀測資料中小流域的防洪預警中具有一定的可行性。 最后對全文進行了總結(jié),并對有待進一步深入研究的問題進行了探討。
[Abstract]:The safe operation of the South-to-North Water transfer Project involves the safety of engineering infrastructure, water quantity, water quality and flood control, among which the safety of water quality is the ultimate goal and fundamental foothold of the project, and the key factor determining the success or failure of the project. This is determined by the nature of the South-to-North Water transfer Project. In order to ensure the safety of water quality in the South-to-North Water transfer Project, this paper evaluates the sudden water quality risk of the South-to-North Water transfer Project in the East Route Project and the Middle Route Project, and points out the types of water quality risk factors. The application of satellite remote sensing rainfall information in small watershed flood control early warning without ground observation data is discussed. The main contents and results of the study are as follows: This paper analyzes the water quality risk of the East Route of South-to-North Water transfer Project, and summarizes the types of water quality risk factors that threaten the water quality safety of the East Route Project and cause sudden water pollution events. This paper analyzes the reasons why Huaian section is selected as a typical channel section of South-to-North Water transfer East Line Project, and divides it into four possible scenarios to simulate and analyze, and to study the emergency control measures and measures for sudden water pollution incidents. 2) the water quality risk of the middle route project of South-to-North Water transfer Project is analyzed, and the types of water quality risk factors which threaten the safety of water quality and cause the sudden water pollution event are summarized. This paper analyzes the reason why Jingshi section is selected as the typical channel section of the middle route of South-to-North Water transfer Project, and divides it into three possible scenarios to simulate and analyze, and to study the emergency control methods and measures for the sudden water pollution event. Taking the Danjiangkou Reservoir Basin as the study area, the precipitation data set of surface rainfall stations on the China Meteorological Science data sharing Network is used to select the 2009-2012 July-September period as the study period. The accuracy of PRE, a 6h precipitation estimation product of Fengyun 2D satellite developed by the National Satellite Meteorological Center, is analyzed, which can be divided into single station rainfall accuracy evaluation and watershed area rainfall comparison analysis. The results show that the accuracy of satellite estimation is high and the estimation ability is strong. It can effectively estimate rainfall and rainfall trend. Taking four small and medium-sized watersheds in Hebei Province along the main trunk channel of South-to-North Water diversion Project as an example, the application of satellite remote sensing rainfall information to flood control and early warning of middle and small watersheds is discussed. The results show that it is feasible to apply satellite remote sensing rainfall information to flood control and early warning of small watershed without ground observation data. Finally, the paper summarizes the full text and discusses the problems to be further studied.
