Calculation of Parameters of Crop Water Production Function based on PSO

摘要：

In this paper, a method based on PSO (particle swarm optimization) is introduced to calculate Parameters of Crop Water Production Function directly. This method can eliminate some problems existing in linear regression method, such as biased estimate and distortion of result. The advantage of this method is that calculating parameters is not influenced by model complexity and initial value, and the higher convergent speed and precision are the character of this method. This method can be proved to be effective by analyzing the example and comparing with the conventional method.
