【摘要】：隨著計算機技術(shù)與遙感技術(shù)的快速發(fā)展，分布式水文模型在國內(nèi)外的應(yīng)用得到了快速地發(fā)展，漳河上游濁漳河關(guān)河水庫以上流域的位于山西省境內(nèi)，是濁漳河的北源。為了更好地對漳河上游區(qū)域降雨徑流進行預(yù)測，為流域管理提供技術(shù)支撐。本文選取濁漳河北源關(guān)河水庫為流域出口，利用SWAT模型對該水庫所控制的水文區(qū)域進行了降雨徑流分析研究，研究內(nèi)容和成果如下： 一、方法選擇�；诂F(xiàn)有的成果，闡述了SWAT模型基本理論的進展，研究方法和分布式水文模型的研究，并利用地理信息系統(tǒng)提取流域水文特性。通過資料的收集與整理，利用ArcGIS9.3軟件對流域的DEM、土壤及土地利用圖進行了相關(guān)處理分析，并提取了坡度圖。通過對數(shù)據(jù)的分析比較，本文選取了由美國農(nóng)業(yè)部研發(fā)的SWAT即Soil and WaterAssessment Tool模型作為基礎(chǔ)水文模型。 二、模型建立。通過對數(shù)據(jù)的處理、相應(yīng)參數(shù)的計算、水文氣象數(shù)據(jù)的整理、蓄飲水工程及區(qū)域經(jīng)濟的分析，將相關(guān)參數(shù)結(jié)合其物理意義逐一調(diào)整分析后輸入模型相應(yīng)參數(shù)，構(gòu)建起模型的數(shù)據(jù)庫。 三、通過對1990-2009年該區(qū)域的月徑流進行模擬，，通過選取校準(zhǔn)期與驗證期，對模型進行校正分析，探討了關(guān)河水庫以上研究區(qū)域降水徑流的關(guān)系，以及模型在該區(qū)域的適用性。結(jié)果證明：模擬評價系數(shù)均在要求范圍以內(nèi)，SWAT模型在關(guān)河水庫以上研究區(qū)域具有較好的適用性，模型的年徑流模擬結(jié)果較好。但與此同時，模型的月徑流模擬在平水年與枯水年份較滿意，而在少數(shù)特殊豐水年份的月模擬結(jié)果存在較大偏差。
[Abstract]:With the rapid development of computer technology and remote sensing technology, the application of distributed hydrological model in China and abroad has developed rapidly. The basin above the Zhuozhang River Guanhe Reservoir in the upper reaches of the Zhangzhou River is located in Shanxi Province and is the northern source of the Zhuozhang River. In order to better forecast rainfall runoff in the upper reaches of Zhanghe River, it provides technical support for watershed management. This paper selects Yuanguanhe Reservoir in Zhuozhang and Hebei Province as the outlet of the basin, and makes use of SWAT model to analyze the rainfall runoff in the hydrological area controlled by the reservoir. The research contents and results are as follows: first, the method is selected. Based on the existing results, the advances in the basic theory of SWAT model, research methods and distributed hydrological models are described, and watershed hydrological characteristics are extracted by GIS. Through the collection and collation of the data, the DEM, soil and land use maps of the watershed were processed and analyzed by ArcGIS9.3 software, and the slope map was extracted. Through the analysis and comparison of the data, the SWAT or Soil and WaterAssessment Tool model developed by USDA is selected as the basic hydrological model. Second, model establishment. Through the processing of the data, the calculation of the corresponding parameters, the arrangement of the hydrometeorological data, the analysis of the water storage project and the regional economy, the relevant parameters are adjusted one by one with their physical meaning and the corresponding parameters of the model are inputted into the model. Build the database of the model. Thirdly, through the simulation of monthly runoff in the area from 1990 to 2009, and by selecting the calibration period and the verification period, the model is corrected and analyzed, and the relationship between precipitation runoff and the applicability of the model in the study area above the Guanhe Reservoir is discussed. The results show that the simulation evaluation coefficients are within the required range, the SWAT model has a better applicability in the study area above the Guanhe Reservoir, and the annual runoff simulation results of the model are better. But at the same time, the monthly runoff simulation of the model is satisfactory in the normal year and the dry year, but the monthly simulation result in a few special high water year has a big deviation.
