| 摘 要： | 基于时间序列的相空间扩维思想,利用神经网络的感知器分类原理,提出一种水文预报方法.直接从水文单因素时间序列滑动生成多维空间的一个相型分布中寻求水文现象变化的规律.并利用湖北省宜昌市沮漳河洪水资料对该方法做了初步验证.

| Abstract: | The problem of mid_long term hydrological forecasting is researched. A set of multidimensional vecteres is formed from one dimension in hydrological time series in terms of the idea of extended dimension principle; and a pattern recognition method is developed to apply to hydrological forecasting. The Juzhang River historical flow data in Yichang of Hubei Province, have been selected for verifying annual flow forecasting. It shows that the proposed method yields a good hydrological forecasting. |
