| 1 | Comprehensive benefit of flood resources utilization through dynamic successive fuzzy evaluation model: A case study显示文摘Taking the flood resources utilization in Baicheng, Jilin during 2002–2007 as the research background, and based on the entropy weight and multi-level & multi-objective fuzzy optimization theory, this research established a multi-level & semi-constructive index system and dynamic successive evaluation model for comprehensive benefit evaluation of regional flood resources utilization. With the year 2002 as the base year, the analyzing results showed that there existed a close positive correlation between flood utilization volume and its benefits, comprehensive evaluation value and its comparison increment. Within the six successive evaluation years, the comprehensive benefit of 2003 was the best, in which the benefit evaluation increment reached 82.8% whereas the year of 2004 was the worst, in which the increment was only 18.2%. Thus the sustainability and correctness of the evaluation were verified by six years successive evaluation and increment comparison. The analyzing results showed that the economic benefits, ecological benefits and social benefits of flood utilization were remarkable, and that the comprehensive benefit could be improved by increasing flood utilization capacity, which would promote the regional sustainable development as well. The established dynamic successive evaluation provides a stable theoretical basis and technical support for further flood utilization. | FENG Feng1,2, XU ShiGuo1, LIU JianWei1, LIU Dan1,3 & WU Bo4 1 Institute of Water Environment, School of Civil and Hydraulic Engineering, Dalian University of Technology, Dalian 116024, China 2 Yellow River Conservancy Technical Institute, Kaifeng 475003, China 3 College of Water Resources, Shenyang Agricultural University, Shenyang 110161, China 4 Office of Flood Control and Draught Relief in Jilin Province, Changchun 130033, China | 2010 | Science China(Technological Sciences)2010，53，2： | 7 |
| 2 | Coupling the hydrological and ecological process to implement the sustainable water resources management in Hanjiang River Basin显示文摘Research on the combination of hydrological variation and ecological demands plays an important role in water availability assessment and sustainable management on basin scale. An integrative frame, consisting of hydrological regime modelling, ecological water demands estimation and renewable resources management, is given in this paper in order to support the implementation of the sustainable water resources management. The suggested integrative frame has been used to study the integrated water resources management in southern Hanjiang River Basin which is the water source of South-toNorth Water Transportation Project in China. SWAT (soil and water assessment tool) model was used to simulate the monthly averaging streamflow and the amounts of ecological water demands in stream were also estimated in order to evaluate the available water resources for the local users and the transportation project. Then we formed the developing scenarioes by coupling the available water resources, the recovering rate of water resources in natural water cycle, the local water use rate and the amounts of the water transported to North, and used the Scheafer model to analyze their evolving trajectories. Eventually, the sustainable water resources management measures were assembled by the comprehensive evaluation of the scenarioes. The research indicates that the integrative frame provided a new way for the integrated water resources management in river basin. | ZHANG Xiang1 & XIA Jun2 1 State Key Laboratory of Water Resources and Hydropower Engineering Science, Wuhan University, Wuhan 430072, China 2 Key Laboratory of Water Cycle and Related Land Surface Processes, IGSNRR, Chinese Academy of Sciences, Beijing 100101, China | 2009 | Science China(Technological Sciences)2009，52，11： | 6 |
