【摘要】：城市水资源是城市建设和发展中不可或缺的重要因素，是人民生活安全的保障。城市生态水系的建设，不仅能美化城市环境，而且起到了维持生态平衡及防洪排涝等作用，对促进生态文明城市的发展建设具有重要意义。本文以青岛高新区生态水系为研究对象，根据区域概况及周边可利用水源的调查分析，展开了对该城区生态水系需水量的预测及补水方案的研究。在研究过程中，本文首先对高新区的概况（地理区位、自然概况、生态水系规划）及周边水资源现状（水量、水质方面）进行了调查分析，为后续生态水系需水量的预测及补水方案的研究提供基础资料。接着，本文研究设计了高新区生态水系建设的总体思路（高新区生态水系优先利用区域雨水径流，其他补水水源进行水量和水质比较，选用投资少、水质优良、水量有保证的最优补水方案），并确定了生态水系需水量的计算方法，即吞吐湖生态需水计算方法，运用该方法对高新区近、远期生态水系进行了水量平衡计算，得到不同降水保证率下高新区生态水系的需水量，为后续高新区生态水系补水方案的选择提供了重要依据。然后，本文根据高新区不同发展时段生态水系的预测需水量及发展规划，对高新区区域及周边可利用水源（雨水蓄集、洪江河客水资源、桃源河客水资源、墨水河客水资源、大沽河客水资源和再生水资源等）进行了补水方案的可行性研究及对比分析，最终推荐最优补水方案，，即近期生态水系采用大沽河南庄橡胶坝拦蓄水源进行补水；远期生态水系采用上马和出口加工区两处污水处理厂再生水进行补水，大沽河南庄橡胶坝水源作为应急补水水源。最后，本文对高新区生态水系补水方案进行了评价，其建成运行后所带来的经济效益和环境效益是非常显著的。
[Abstract]:Urban water resources are an indispensable and important factor in urban construction and development, and guarantee the safety of people's lives. The construction of urban ecological water system can not only beautify the urban environment, but also maintain ecological balance and flood control and drainage. It is of great significance to promote the development and construction of ecological civilization city. This paper takes the ecological water system of Qingdao High-tech Development Zone as the research object, according to the regional situation and the investigation and analysis of the available water sources around it. The prediction of the water demand of the ecological water system and the study of the water supply scheme are carried out in this paper. In the course of the research, this paper first makes an investigation and analysis on the general situation of high-tech zones (geographical location, natural situation, ecological water system planning) and the surrounding water resources status (water quantity, water quality). This paper provides basic data for the prediction of water demand of ecological water system and the study of water supply scheme. Then, this paper studies and designs the general idea of ecological water system construction in high-tech zone (the ecological water system of high-tech zone preferentially uses regional runoff, For comparison of water quantity and water quality in other water supply sources, the optimal water supply scheme with less investment, good water quality and guaranteed quantity of water is selected, and the calculation method of water demand of ecological water system, I. e., the calculation method of ecological water demand of Lake Huantuhu is determined. The method is used to calculate the water balance of the near and long term ecological water system of the high and new technology zone, and the water demand of the ecological water system of the high and new technology zone is obtained under different rainfall guarantee rates, which provides an important basis for the selection of the water supply scheme of the ecological water system in the following high and new technology zones. According to the forecast water demand and development plan of ecological water system in different development periods of high and new technology zone, this paper makes use of water resources (Rain Water storage, Hongjiang river guest water resources, Taoyuan river guest water resources, ink river guest water resources, ink river water resources, etc. The feasibility study and comparative analysis of the water supply scheme are carried out, and the optimal water supply scheme is recommended, that is, the ecological system uses the rubber dam of Dagu river to replenish water in the near future. In the long term, the reclaimed water of two sewage treatment plants in Shangma and export processing zone is used to recharge water, and the water source of rubber dam in Dagu Hen Zhuang is used as the emergency water source. Finally, the paper evaluates the scheme of water supply for ecological water system in high and new technology zone. The economic and environmental benefits brought by its completion and operation are very remarkable.
