With the rapid development of economy and the increasing of population,the contradiction of supplement and requirements about water resources becomes obvious in Henan Yellow River Water Irrigation District.Therefore,it is neccessary to strengthen the study on water resource,analyze the potentiality in depth,which is of great importance to water resources optimization management and the fully development and utilization of water resources in Henan Yellow River Water Irrigation District.By combining BP(Back-Propagation) neural network with RAGA(based on Real number code to Accelerating Genetic Algorithm) together,it remedies the deficiency of each algorithm,it has set up the comprehensive evaluation model for development and utilization of regional water resources based on RAGA-BP method.At last,the method is applied to Henan Yellow River Water Irrigation District.The results show that the intensity or level of regional water resources utilization is in the low intermediate level,the development of water resources has greater potentiality,which is suited to the regional actual conditions;In addition,this method has a fast speed of convergence weights and high precision.It can be widely used in the comprehensive evaluation of relevant water resources questions.
