【摘要】：现代水网建设是解决水资源短缺、生态环境不断恶化的重要手段。本文选取山东省青州市作为典型研究区域,基于青州市现代水网规划建设工程,在对水资源进行优化配置的基础上,对现代水网建设的水资源生态效应进行综合评价。主要研究内容如下:(1)青州市水资源概况及现代水网建设工程阐述分析基于青州市水文气象等基本资料,对青州市的水资源状况、水资源开采利用现状与开发利用中存在的问题进行分析,并对青州市的现代水网规划工程与建设情况进行系统阐述,为水资源优化配置提供依据。(2)水资源供需平衡分析根据青州市经济社会发展状况及水资源开发利用中存在的问题,对青州市规划水平年2020、2025年的不同用水户的需水量进行预测分析。在生态需水量的分析计算过程中,分别计算了河道内和河道外的生态需水量,针对河道内生态需水量,研究了基本生态流量及适宜生态流量的计算方法,提出了两级临界生态需水的量化途径,并在此基础上进行了供需水平衡分析。(3)基于水网规划建设的水资源优化配置基于青州市水网规划建设工程构建青州市水资源优化配置模型,以社会效益与经济效益最大为目标,使用LINGO软件编程进行优化配置模型的求解,计算得出规划水平年2020年与2025年在50%、75%及95%三种保证率下的水资源优化配置结果。(4)水网建设工程的水资源生态效应评价基于水资源优化配置结果构建水资源生态效应评价指标体系,并采用可变模糊集评价方法对现状年及规划水平年的水网建设工程的水资源生态效应进行综合评价,评价结果表明,现代水网的建设可有效改善青州市水生态环境,对青州市的水资源环境改善及社会经济协调发展具有一定指导意义。
[Abstract]:The construction of modern water network is an important means to solve the shortage of water resources and the deterioration of ecological environment. In this paper, Qingzhou City of Shandong Province is selected as a typical research area. Based on the planning and construction project of modern water network in Qingzhou City, the ecological effect of water resources of modern water network construction is comprehensively evaluated on the basis of optimal allocation of water resources. The main research contents are as follows: (1) the water resources in Qingzhou City are analyzed based on the basic data of hydrology and meteorology in Qingzhou City, and the situation of water resources in Qingzhou City is analyzed. The present situation of exploitation and utilization of water resources and the problems existing in the exploitation and utilization of water resources are analyzed, and the planning and construction of modern water network in Qingzhou City are systematically expounded. To provide the basis for the optimal allocation of water resources. (2) the analysis of water resources supply and demand balance according to the economic and social development of Qingzhou City and the problems existing in the development and utilization of water resources, The water demand of different water users in the planning level of Qingzhou City in 2020,2025 was predicted and analyzed. In the process of analysis and calculation of ecological water demand, the ecological water demand in and out of the river is calculated, and the basic ecological discharge and the suitable ecological discharge calculation method are studied in the light of the ecological water demand in the river. A quantitative approach to two-level critical ecological water demand is proposed. On this basis, the water supply and demand balance analysis is carried out. (3) the optimal allocation of water resources based on the water network planning and construction project of Qingzhou City is built to build the water resources optimal allocation model of Qingzhou City. Aiming at the maximum social and economic benefits, the optimal configuration model is solved by using LINGO software, and the planning level in 2020 and 2025 is calculated. The results of optimal allocation of water resources are 75% and 95%. (4) based on the results of optimal allocation of water resources, the evaluation index system of ecological effects of water resources is constructed. The evaluation method of variable fuzzy set is used to evaluate the ecological effect of water resources of water network construction project in current year and planning level year. The result shows that the construction of modern water network can effectively improve the water ecological environment of Qingzhou City. It has certain guiding significance for the improvement of water resources environment and the coordinated development of social economy in Qingzhou City.
