Abstract


Environmental problems brought by the development of social and economic have become increasingly remarkable, so countries all over the world are dedicating to the construction of eco-city. Binhai New Area in the process of building eco-city faces the pressure of high intensity of development and great demand of resources. As a scarce resource, water performs a key factor in the construction of eco-city. To increase the ability of the government’s macro-regulation, promote the efficiency of using water, guide industrial restructuring and ensure coordinative development of social, economy, ecology and environment, water resources allocation for eco-city associates with importance.Eco-city water system is huge and complicated with the uncertainty of economic, policy, nature and planning. Taking the year of 2008 as the actuality year, 2010 and 2020 as the planning years, this paper studies the IFMOP model based-on uncertainty theory to allocate the water resources of Binhai New Area, reveals the real uncertain factors in the form of interval parameter, solves the model in the interval range, and obtains the solution of the model by interactive calculation between the decision-makers and the model.Firstly, the water resources and current situation of water-supply, water-use, and water-drain of BinHai New Area are analyzed, and the main water problems are put forward.Secondly, available water and water demanded of 2010 and 2020 are forecasted under current water resources situation and existing planning, then the balance between supply and demand is analyzed. Available water involves surface water, groundwater, water transfered, sea water and reclaimed water. Available water of 2010 is 11.38 billion cubic meters, and that of 2020 is 17.83 billion cubic meters. System of water demanded includes agriculture, industry, tertiary industry, urban life, rural life, river and lake water supplement, landscaping and road-pouring. Water demanded of 2010 is 12.24 billion cubic meters, and that of 2020 is 18.04 billion cubic meters. The results of supply and demand balance analysis show that supply-requirement ratio of 2010 is 92.97%, and that of 2020 is 98.84%, which reaches approximately equilibrium. Further measures for the adjustment of water supply and demand are put forward as the basis of water resource allocation in this paper.Then, at the aim of economic and ecological optimization, with the amount of water resources and nonnegative constraints as constraint conditions, IFMOP model is built and solved by programing with the software MATLAB. The results of water resources allocation for 2010 and 2020 are obtained.At the end of the paper, schemes of water resources allocation for Binhai New Area are given according to the solution of IFMOP model, which can provide reference for macro-allocation of Binhai New Area water resources.
