摘　　要：岚河流域是汉江流域的一个暴雨中心，降雨分布很不均匀。通过总结岚河流域的特点，设计 了洪水预报模型，通过对历史雨量数据的分析计算，校验了模型参数的准确性，并将此模型应用至 蔺河口水电站水调自动化系统洪水预报系统中，在2004年的几场洪水中，预报系统发挥了相当重 要的作用，保证了电站大坝、厂房及下游人民的生命安全。预报模型采用三水源新安江模型，实现 定时预报、补做预报、估计预报、图形显示等功能，通过蔺河口电站洪水预报系统的成功实施，基本 找到并摸清了汉江支流岚河的洪水规律。The Lanhe valley is a rainstorm center of the Hanjiang drainage basin, where the rainfall is uneven. Based on the characteristics of the Lanhe valley, a flood forecasting model is designed. With the calculation for the historical data of rainfall, the veracity of the parameters of the model is verified. And the model is applied to the flood forecasting system of the waterpower scheduling automation system of the Linhekou Hydropower Station. The forecasting system played an important role during the floods in 2004. The Xin＇ anjiang three-source model is used to realize timing forecast, remaking forecast, estimating forecast and graph display. With the successful application of the flood forecasting system to the Linhekou Waterpower Station, the flood evolution of the Lanhe valley is realized.
