Study On The Sustainable Utilization Water Resources Assessment Method And Its Application Of River Basin

Water is vital headspring and also is nonreplaceable resource of human being depending on survive. Water resources are indispensable natural resources of humanbeing in producing and living and also are economic resources of supporting healthy development of national economy& environmemntal resources of living being depending on survive. Water resources have already changed modern social bottle-neck resources by degrees and have badly restricted developmemt of a district a nation or even the global at present. Water resources have already become key problem in 3 tasks of population resources and environment of world facing nowadays. Sustainable utilization of water resources is of great important ensure realizing sustainable development of society economy and ecology environment. Sustainable utilization of water resources is a kind of new mode of utilization of water resources under sustainable development frame and also is only method solving water resources crisis. Chaohe river basin, is situated at upstream of Miyun reservoir in Beijing Municipality, originates from Fengning County Chengteh Municipality Hebei Province, are important water source and ecological barrier in capital Beijing at present. It is very important of doing well sustainable development and utilization of water resources in Chaohe river basin to solve problems of water resources shortage water resources pollution and ecological deterioration in Beijing region's socioeconomic development undoubtedly. The author has gained main research findings, a case study of Chaohe river basin, using technical line of combining with theory& mothod study and application example, on the basis of combined the domestic and international relevant documents& materials and based on the achievements of predecessors.1.The application problem of Unascertained systems theory in Chaohe river basin sustainable development and utilization of water resources evaluation has been explored using AHM etc and index weight values calculation model in the fuzzy synthetical evaluation system has been set up.2.The dynamic analog simulation of system dynamics has been completed and the analog result has been overall evaluated of more factors and long term effect of measures in the system has been explained at the angle of quantitative for commonly used utilization of water resources measures in the action of socioeconomic environment system, on the basis of theoretical connotation of interrestriction with water supply and water need systems, taking Chaohe river basin as field of resarch, on the basis of studying water cycle and water quantity conversion rule.3.The urgency of implementing virtual water trade& virtual water strategy and the necessity of implementing water bank system have been system argumentated in Chaohe river basin for the first time.4. A basic way to realize of SVC and SVR has been described and have been used Chaohe river basin evaluation of the sustainable usage of water resource and a practicable evaluation conclusion has been obtained and a new idea and approach have been offered for sustainable development evaluation.5.The optimizing configuration results have been obtained of different frequency in three level years and basic& balance schemes in Chaohe river basin, confirming other parameters in the model at the same time, inversion water utilization benefit coefficient of various departments by benefit coefficient robustness, setting up water resources optimal allocation combining Chaohe river basin practical situation.6. Artificial fish-swarm algorithm has been tried to use in multicriteria parametric combination model optimization of Chaohe river basin evaluation of the sustainable usage of water resource combining basin sustainable development characteristics and parametric multiindex evaluation formula has been obtained suitable for Chaohe river basin evaluation of the sustainable usage of water resource. The evaluation result of the formula calculating the example comes near to the factual value.7.Water resources reasonable configuration safeguard measures in Chaohe river basin have been put forward.
