Set Pair Analysis Method for Evaluating Reproducible Ability of Water Resources

Scientifically and reasonably evaluating reproducible ability water resources of can provide decision basis for exploitation and utilization of water resources.The various systematic analysis evaluation methods have already been widely used to evaluate reproducible ability of water resources,but the results of evaluation are mostly discrete values which can't accurately reflect reproducible ability of water resources.According to analyzing hierarchical structure of identity-discrepancy-contrary for set pair,the method of "hierarchy approach of identity-discrepancy-contrary" for confirming connection number is proposed.And the set pair analysis method for evaluating reproducible ability of water resources is established,which is used to evaluate the reproducible ability of water resources in Yellow River basin.Analytical study results indicate that the theory of this method is simple and the result of its evolution is accurate,so this method has a wide application value in hydrology and water resources.
