摘要: 水是生命之源,是人类赖以生存的物质基础.水资源是基础性的自然资源和战略性的经济资源.水资源的可持续利用是社会经济发展的前提.滦南县是河北省农业生产大县,随着国民经济的快速发展,需水量也在迅速增长,区域内水资源供需矛盾非常突出,滦南县县城所在的水资源分区现状年地下水开采系数已达到1.27,属于一般超采.优化配置水资源使有限的水资源发挥最大的效益和效率已成为滦南县经济社会可持续发展的必然选择.因此本论文针对滦南县水资源优化配置进行研究. 通过对滦南县的地表水、地下水等研究分析,从而计算出滦南县的水资源可利用量.通过对供水量调查、社会经济用水调查、现状年用水分析、水资源开发利用程度分析、水资源现状供需分析等,揭示了滦南县现状年水资源开发利用存在的问题和供需矛盾,为滦南县有限的水资源的优化配置提供了现实基础. 通过预测滦南县规划水平年的人口数量、城镇化率、三产增加值等指标和在强化节水条件下的需水定额,计算得到规划水平年需水量.根据规划水平年需水要求并参考相关规划制定了常规水源和非常规水源供水规划,并计算得到规划水平年总可供水量. 针对滦南县为农业大县、区域面积小、水资源调配相对容易、水资源在行业间的分配矛盾较为突出等特点,在滦南县供需水预测成果的基础上,建立了以区域经济效益最大为主要目标、区域社会效益最大为次要目标、以区域供水能力、输水能力、需水能力等因素为约束条件的水资源多目标优化配置模型,根据Excel和Matlab的特点,把Excel作为数据输入端,调用Matlab中的linprog工具函数求解该模型,得到了滦南县水资源优化配置成果.经分析,该配置成果是合理可行的,可作为滦南县水资源规划与管理的决策依据. 为保障水资源优化配置成果能够顺利实现,制定了节水实施方案、增加供水实施方案和水资源综合管理建设方案,并对方案实施后的效果进行了评价.规划实施后,水资源供给保障能力与经济社会发展和生态环境保护基本协调,整体性水资源约束有所缓解.
英文摘要: Water is the source of live and the basis of substance. Water resources are the foundational natural resources and the strategic economical resources. To achieve the sustainable development of the society and economy, we must realize the sustainable use of water resources first. Luannan County is a county of Hebei Province which majors in agriculture. With the social and economic rapid development, the quantity of water requirement is becoming much higher, but the available water resources is limited, so the contradiction between water supply and requirement is very heavy, and the groundwater exploitation coefficient of the water resources subarea in which there is the county seat of Luannan County has been 1.27, which belongs to commonly exceeded exploitation. Water resources optimizing allocation, namely maximizing the efficiency and benefits of water resources will be the certain choice for sustainable development of Luannan economic society. In this thesis, how to effectively use the limited water resource has been discussed.By analyzing Luannan County''''s surface water and ground water and so on, Luannan County''''s available water quantity is received. By water supply survey and society and economy water using survey and water using analysis in present year and water resources exploitation and using analysis and water resources supply and require analysis in present year and so on, water resources exploitation and using existent problem and contradiction between supply and requirement are opened out, which affords basic data for the optimization distribution of limited water resources in Luannan County.By forecasting Luannan County''''s population quantity and the ratio between town and village and the increased value of three industries and water requirement ration in the condition of aggrandizement economy water using, water requirement quantity in plan level years is received. In according of water requirement quantity in plan level years and consulting interrelated water supply programming, available water supply quantity is received.In allusion to the characteristics that Luannan County is a county which majors in agriculture and its area is small and its water resources allocation is relatively easy and the contradiction of water resources allocation among industries is severe and so on, based on the predicted water supply and demand for Luannan County, water resources multi-objective optimal allocation model is founded. The model are made up of primary object which is that the district economical benefit is most and by-end which is that the district social benefit is most and restricts which contain water supply capability and water transportation capability and water demand capability and so on. And the model is solved through data input with Excel and transferring Tool Function linprog of Matlab, and then the allocation production is received. By analyzing, the allocation production is believed reasonable and feasible, and it can be decision-making gist of Luannan County water resources layout and management.Economy water using scheme and increasing water supply scheme and water resources integration management construction scheme are established to ensure water resources optimization allocation fruit realized at right, and the effect is appraised after schemes carried into execution. After schemes carried into execution, water resources supply indemnificatory ability is basically harmony with economic society development and entironment protection, and the whole water resources restriction has lessened.
