Regional water resources rational allocation is an effective way to solve the region’s growing water shortage, to evaluate the status of water resources in the region, and study how the limited water resources to be able to host the sustained and healthy development of regional economic, social, ecological environment, the need are effective regional water resources rational allocation. The study reviews the rational allocation of water resources at home and abroad, and on the basis of the actual situation according to the study area Zhoukou City, the region’s water resources rational allocation and the overall efficiency of the configuration program evaluation studies, the main contents and conclusions are as follows:(1) Analysis the water resources status of the study region, a comprehensive evaluation of water resources carrying capacity for each sub-area. Investigation and analysis water use situation of Zhoukou City, analysis and research the existing problems in the development and utilization of water resources. According to the water resources bearing capacity factors, formating water resources carrying capacity evaluation index system; introduce support vector machine technology, use theory of structural risk minimization principle in statistical learning, as well as the advantages to solve the non-linear and high-dimensional identification, especially to overcome the subjective factors adversely affected, build a comprehensive evaluation model of regional water resources carrying capacity, and comprehensive evaluate the resources carrying capacity of Zhoukou City, and to provide a basis for the rational allocation of regional water resources.(2) According to the the economic laws of social development and utilization of water resources in the current situation of the study area, the planning year of the study area economy, society and industry water consumption trends analysis, formating a prediction model for the study area characteristics, and forecast the water demand in the planning year of the study area promoter region.(3) Constructing the rational allocation model of regional water resources, the model of regional water resources is built with the purpose of maximizing the comprehensive economic, social and environmental benefits of regional water consumption. In order to solve the problems that easily appear during the model solution of regional water resource optimal allocation with multiple water sources, multiple users and multiple objectives like "Curse of Dimensionality" or sinking into local optimum, this paper has proposed a particle swarm optimization algorithm based on immune evolutionary algorithm. This algorithm introduces immunology principle into particle swarm algorithm. Its immune memorizing and self-adjusting mechanism is utilized to keep the particles in the fitness level at a certain concentration and guarantee the diversity of population. Also, the global search characteristics of immune evolutionary algorithm and the local search capacity of particle swarm algorithm have been fully utilized to overcome the dependence of particle swarm optimization on initial swarm and the deficiency of vulnerability to local optimum. After applying this model to the allocation of water resources in Zhoukou, we obtain the scheme for optimization allocation of water resources in the planning level years, i.e.2015and2025under the guarantee rate of75%. The calculation results indicate the application of this algorithm to solve the issue of optimal allocation of regional water resources is reliable and reasonable, thus offering a new idea for solving the issue of optimal allocation of water resources.(4) Overall benefit evaluation of the the water resources allocation program. Systematic study of the overall efficiency of the whole process of the program evaluation, establish the allocation of water resources program effectiveness evaluation model based on fuzzy matter-element and Entropy iteration theory, the model introduces the theory of entropy in information theory, evaluation index itself reflects the disordering effect value of the information to calculate the weight value so that the weight of calculating theoretical basis. At the same time, the combination of subjective weight and Entropy form a comprehensive weight, give full consideration to the subjective weight and objective weight contains information, taking into account the expert opinion and objective data attributes, the results of the evaluation more objective and credible. The evaluation showed high overall efficiency of the rational allocation scheme obtained by solving the optimization model, and practical guidance to achieve scientific development to the region.(5) For the growing water problem Zhoukou, the scientific development concept as a guide, specific measures are proposed for scientific development of the regional. The research results have certain guiding significance on the promotion of regional water resources rational allocation and the sustainable development of regional economic, social and ecological environment.
