【摘要】：水是人類賴以生存和發(fā)展的重要自然資源,也是自然生態(tài)環(huán)境重要的制約因素。隨著社會的進步,經(jīng)濟的發(fā)展,水資源的需求量日益增加,使得水資源供需矛盾日益突出,解決水資源危機已成為世界范圍的戰(zhàn)略性問題之一。烏蘭察布市集寧區(qū)處于水資源較貧乏地區(qū),據(jù)有關(guān)資料統(tǒng)計,集寧區(qū)現(xiàn)已探明的四個集中供水水源地均已達到開采極限。根據(jù)集寧區(qū)整體發(fā)展規(guī)劃,城區(qū)建設(shè)規(guī)模將發(fā)展為人口100萬人,單純依靠現(xiàn)有的四個水源地,地下水資源量遠遠不能滿足城鎮(zhèn)建設(shè)工業(yè)生產(chǎn)和居民生活用水要求。隨著城鎮(zhèn)工業(yè)生產(chǎn)的發(fā)展,對水資源的需求量將日益增大,水資源短缺的問題,已嚴重制約集寧區(qū)的城鎮(zhèn)建設(shè)及工業(yè)生產(chǎn)的發(fā)展。因此有必要建立地下水數(shù)值模擬模型來定量研究內(nèi)蒙集寧大理巖地區(qū)地下水資源,給地下水資源的合理開發(fā)利用和科學管理提供依據(jù),為滿足集寧區(qū)國民經(jīng)濟發(fā)展總體規(guī)劃與產(chǎn)業(yè)結(jié)構(gòu)調(diào)整提供水文地質(zhì)資料。本文通過搜集、分析和整理研究區(qū)內(nèi)已有的地質(zhì)、水文地質(zhì)研究成果,分別運用地下水數(shù)值模擬軟件MODFLOW和GMS構(gòu)建內(nèi)蒙集寧大理巖地下水水流模型。通過2001至2011年的地下水動態(tài)觀測資料,先給定參數(shù)和邊界初值,通過手動和自動調(diào)參對模型進行校正,比較模型計算值與實際觀測值的擬合程度,并不斷地調(diào)試、修正參數(shù)初值,達到最好的擬合效果。然后再與2011年的統(tǒng)測水位值進行擬合,以進一步驗證模型的可靠性和適應(yīng)性。識別與驗證均達到了很好的效果,表明模型的參數(shù)與邊界的概化都是合理的,模型可以進行地下水水位預測,并對研究區(qū)域進行了地下水動態(tài)預測。最后對兩個軟件在進行地下水數(shù)值模擬的操作進行比較,分析并描述了兩個軟件在應(yīng)用中各自的優(yōu)勢所在。
[Abstract]:Water is not only an important natural resource for human survival and development, but also an important restriction factor for natural ecological environment. With the progress of society and the development of economy, the demand for water resources is increasing day by day, which makes the contradiction between supply and demand of water resources more and more prominent. Solving the crisis of water resources has become one of the strategic problems in the world. The Jining district of Wulanchabu city is in the poor area of water resources. According to the statistics, the four water sources of concentrated water supply in Jining district have reached the limit of exploitation. According to the overall development plan of Jining District, the scale of urban construction will be 1 million people. Depending on the existing four water sources, the quantity of groundwater resources is far from meeting the requirements of urban construction industry production and residents' domestic water use. With the development of industrial production in cities and towns, the demand for water resources will increase day by day. The shortage of water resources has seriously restricted the construction of towns and the development of industrial production in Jining area. Therefore, it is necessary to establish a numerical simulation model of groundwater to quantitatively study groundwater resources in Jining marble area of Inner Mongolia, which provides the basis for the rational development and utilization of groundwater resources and scientific management. Hydrogeological data are provided for the overall plan of national economic development and adjustment of industrial structure in Jining district. Based on the collection, analysis and collation of the existing geological and hydrogeological research results in the study area, the groundwater flow model of Jining marble in Inner Mongolia is constructed by using the numerical simulation software MODFLOW and GMS, respectively. Based on the groundwater dynamic observation data from 2001 to 2011, the model is corrected by manual and automatic adjustment of parameters and initial boundary values, and the fitting degree between the calculated values of the model and the observed values is compared, and the model is debugged continuously. Correct the initial value of the parameters to achieve the best fitting effect. Then the model is fitted with the measured water level in 2011 to further verify the reliability and adaptability of the model. The results of identification and verification show that the parameters and boundaries of the model are reasonable and the model can be used to predict the groundwater level and the groundwater dynamic prediction is carried out in the study area. Finally, the operation of numerical simulation of groundwater is compared between the two softwares, and the advantages of the two softwares in the application are analyzed and described.
