摘要
本文基于灰色预测原理和双向差分理论，提出长期径流预报的灰色双向差分模型，实例应用表明，该模型由于获取了较多的历史径流信息，不仅能得到较为准确的径流预报值和拟合结果，还可得到非常可靠的长期径流趋势预报结果。
This paper, based on the grey tendency idea and two-way difference theory,gave our a grey two-way difference model of long-term runoff forecasting. The results show that it is advantageous not only in forecasting the volume of runoff but also in forecasting the run-off tendency.
