Elman Network Model for Comprehensive Assessment of Regional Water Resources Carrying Capacity

摘要

It is difficult to establish the mathematics model and control the precision of the assessment models for comprehensive assessment of regional water resource carrying capacity. In order to solve the incompatible indexes problem and to raise the assessment model precision for regional water resources carrying capacity, the method, structure, design, simulation and output of Elman network for comprehensive assessment of regional water resources carrying capacity are given. As an example, regional water resources carrying capacity is assessed for 18 cities in Henan province by Elman network model. The result shows that the model has the features of directness, credibility and good application. The precision of assessment result of Elman network model is higher than that of RBF network model. Not only the precision is high for the Elman network model, but it also has high stability. Comparing with fuzzy analysis method, Elman network model has a better function of arrangement.
