基于密切值法的浑河流域水资源承载能力评价 总被引:1,自引:0,他引:1
根据水资源承载能力评价指标体系建立的原则,将浑河流域发展分为水资源、社会、经济以及生态环境4个子系统,建立浑河流域水资源承载能力评价指标体系。以2005年为基准(现状)年,以2020年为近期规划水平年,以2030年为远期规划水平年,采用密切值法对浑河流域水资源承载能力进行评价。结果表明:浑河流域各区域水资源承载能力整体较差,其中抚顺、铁岭情况优于其他地区;规划水平年的水资源承载能力较现状年有所提高,但水资源开发利用潜力仍然很小。 相似文献

水资源综合评价对实现社会、经济和环境的可持续发展具有重要意义。以水贫困指数为基础,建立了水资源安全综合评价指标体系,探讨了基于层次分析法的水资源安全模糊综合评价方法,并对中国主要流域和分区的水资源安全状况进行综合评价。结果表明:黄河、海河、淮河和长江流域水资源贫困指数较小,开发潜力较小,其它流域和分区水资源贫困指数较大,有一定的开发潜力。经对比分析表明,评价结果与事实基本相符,说明本文建立的层次模糊综合评价模型是可靠有效的,能为水资源规划、跨流域调水和水利工程运行提供较可靠的水文依据。 相似文献

Regional Water Use Structure Optimization Under Multiple Uncertainties Based on Water Resources Vulnerability Analysis 总被引:1,自引:0,他引:1
In this paper, a modeling framework by combining system dynamic (SD) model and optimal allocation model was developed to study water resources vulnerability and optimal water use structure, and the framework was applied in the middle reaches of Heihe River basin, northwest of China. The SD model could describe the dynamical change of water resources vulnerability by integrating water resources with socio-economic effect. The sensitivity analysis of SD model was then conducted to design appropriate scenarios for finding out the optimal development pattern, and based on which, an integrated water-saving scenario with lower water resources vulnerability was identified for optimization modeling. Then, an inexact fuzzy-parameter two-stage programming (IFTSP) model was developed and applied to optimize water use structure among industries under uncertainties. This study addresses the water resources vulnerability analysis in considering both water resources system and socio-economic system. Water resources vulnerability analysis was combined with optimization model to make adaptive water resources management plans. And the optimal allocation schemes under lower water resources vulnerability are more advantageous for regional sustainable development. 相似文献

Optimal Long-term Operation of Reservoir-river Systems under Hydrologic Uncertainties: Application of Interval Programming 总被引:2,自引:1,他引:1
Long-term basin-wide reservoir-river operation optimization problems are usually complex and nonlinear especially when the water quality issues and hydrologic uncertainties are incorporated. It is due to non-convex functions in water quality modeling and a large number of computational iterations required by most of stochastic programming methods. The computational burden of uncertainty modeling can be reduced by a special combination of uncertainty modeling and interval programming, though the problem solution is still a challenge due to model nonlinearity. In this paper, an integrated water quantity-quality model is developed for optimal water allocation at river-basin scale. It considers water supply and quality targets as well as hydrologic, water quality and water demand uncertainties within the nonlinear interval programming (NIP) framework to minimize the slacks in water supply and quality targets during a long-term planning horizon. A fast iterative linear programming (ILP) method is developed to convert the NIP into a linear interval programming (LIP). The ILP resolves two challenges in NIP, first converting the large non-linear programming (NLP) into a linear programming (LP) with minimum approximation and second reducing the iterations needed in interval programming for NLP into just two iterations for the upper and lower limits of decision variables. This modeling approach is applied to the Zayandehrood river basin in Iran that has serious water supply and pollution problems. The results show that in this river basin at dry conditions when available surface water resources are below 85 % of normal hydrologic state and water demands are 115 % of current water demands, the total dissolved solids (TDS) concentration can be reduced by 50 % at the inlet of the Gavkhuni wetland located downstream of the river basin. 相似文献
