【摘要】：流经甘肃、内蒙古、青海的黑河,是我国西北地区的第二大内陆河。流域中游地区是甘肃省重要的粮食基地,其中张掖有“丝绸之路和今日欧亚大陆之要塞”的美称,素有“金张掖”的称誉。下游的额济纳旗地区广阔,其中有我国重要的国防科技基地,居延三角地带的额济纳绿洲,是保护当地人民生息的生命线,也是维持民族团结的的关键所在。黑河流域水资源稀缺,特别是从上世纪八十年代开始,中游地区的用水急剧增大,导致下游地区的用水一度减少,致使中下游地区间的用水矛盾激化,下游的生态环境退化严重。根据相关研究成果,现状年下游的绿洲面积较八十年代已经减少近一半。本文从缓解中下游间的用水矛盾出发,分析了黄藏寺水库建成前后,中下游地区用水保证率的情况,并制定了基于调配模型的不同用水情况的具体方案,运用评价模型对方案进行优选,在此基础上制定水库的调度规则,论文的主要内容和取得的主要研究成果如下:(1)对比分析了黄藏寺水库建成前后的中游灌溉和下游的生态保证率情况,得到水库建成后对黑河流域产生的积极效应,为分析黄藏寺建成后的运行提供科学依据。(2)运用调度模型和配置模型,对不同的分水用水情况进行分析,得到18个方案。制定了 6个初始指标,运用主成分分析法得到4个主要指标;采用熵值法、模糊物元法、投影寻踪法和非负矩阵法对方案集进行评价分析,对评价结果进行一致性分析;同时运用序号总和理论对不同方法的评价排序结果求和,得到最优方案。(3)分别采用调度图和调度函数的形式,来提取水库的调度规则,其中调度函数应用二元线性回归,BP神经网络提取。
[Abstract]:The Heihe River, which flows through Gansu, Inner Mongolia and Qinghai, is the second largest inland river in northwest China. The middle reaches of the river basin is an important grain base in Gansu Province. Zhangye, known as "Silk Road and the Fortress of Eurasia today", is known as "JinZhangye". The downstream Ejina Banner is a vast area, including our important national defense science and technology base, Ejina oasis in the Triangle, which is the lifeline to protect the local people, and also the key to maintain the national unity. Water resources are scarce in the Heihe River Basin, especially since the 1980s, when the water use in the middle reaches increased sharply, leading to a decrease in the water use in the lower reaches, which led to the intensification of water use conflicts between the middle and lower reaches. The ecological environment of the lower reaches is degraded seriously. According to the relevant research results, the oasis area in the downstream of the current year has been reduced by nearly half compared with the 1980's. In order to alleviate the contradiction of water use between middle and lower reaches, this paper analyzes the situation of water use guarantee rate before and after the completion of Huangzangsi Reservoir, and formulates specific schemes for different water use situations based on the allocation model. On the basis of the optimal selection of the scheme by using the evaluation model, the operation rules of the reservoir are worked out. The main contents and main research results of this paper are as follows: (1) A comparative analysis of the irrigation in the middle reaches of the Huangzangsi Reservoir before and after the completion of the reservoir and the ecological guarantee rate of the lower reaches are made, and the positive effects of the reservoir on the Heihe River Basin after the completion of the reservoir are obtained. In order to analyze the operation of Huangzangsi after completion, the paper provides a scientific basis for the operation of Huangzangsi. (2) by using the dispatching model and the configuration model, the paper analyzes the different water distribution situation and obtains 18 schemes. Six initial indexes were established and four main indexes were obtained by principal component analysis (PCA). Entropy method, fuzzy matter-element method, projection pursuit method and non-negative matrix method were used to evaluate and analyze the scheme set, and the consistency of the evaluation results was analyzed. At the same time, summing up the evaluation results of different methods by using the ordinal number summation theory, we get the optimal scheme. We use the form of dispatching graph and dispatching function respectively to extract the regulation rules of reservoirs. The scheduling function is extracted by binary linear regression BP neural network.
