摘  要:
根据农业价格指数构建了农产品价格数据仓库,充分利用长期积累的大量反映价格指标的历史和现在数据资源,并结合径向基函数(RBF)人工神经网络建模,揭示农产品价格与畜牧业、林业与渔业等相关因素价格的动态关系模型。结果表明该模型能够很好地预测以白菜为例的农产品价格,实现农产品区域供求平衡,并为政府和农户提供结构调整的依据。

摘  要:
Farm produce price data warehouse was established according to the agriculture price indices.The dynamic relationship model of farm produce price with stock rising,forestry and fishery was built based on the numerous accumulated history and present data resources which could reveal the price indices combining with RBF neural network modeling.The result proved that the model could simulate and forecast the price trend of cabbage correctly,providing an important method for the accurate forecast of agricultural product market information.
