摘　　要：为了将水产养殖水色判别传统技术经验转化为可以量化的数字技术,采用基于L-M神经网络优化算法和计算机图像处理技术的方法,建立了一个水色判别的水产养殖专家系统。通过实例预测,该系统判别误差率<1%。该系统训练后的神经网络模型,能实现对养殖池塘水质的预测。系统的开发和使用对实现水产健康养殖、智能控制和计算机管理具有一定实用价值.In order to distinguish the traditional water color of aquaculture technology experience into quantifiable digital technology.An aquaculture expert system for identification of water color was established based on Levenberg-Marquardt（L-M） algorithm for neural network optimization and image processing technology.The system conducts water＇s color image preprocessing,to extract effective values of image feature,to train model of neural network to achieve the forecast of water quality.The results show that the system identification error rate is less than 1%.The trained neural network model of this system,network model after training of can be able to predict water quality of the breeding ponds.System development and use to the realization of aquatic healthy breeding,intelligent control and computer management have certain practical value.
