南湾水库位于河南省信阳地区,总库容16.3亿立方米,设计灌溉面积112.4万亩,多年来一直担负着防洪除害的双重任务。因此,水库控制运用调度的好坏,直接影响着信阳地区工农业生产的发展。对未来水资源信息的提前预测预报,是搞好水库控制运用调度,确保工程安全,合理供水,发挥最大经济效益的重要因素。为此,现对南湾水库1991年水资源信息做出预报,并提出供水调度建议:
Nanwan Reservoir is located in Xinyang, Henan Province, with a total storage capacity of 1.63 billion cubic meters and an designed irrigated area of 1,124,000 mu. It has shouldered the dual task of flood control and pest control over the years. Therefore, the operation and control of reservoir control scheduling is good or bad, directly affect the development of industrial and agricultural production in Xinyang area. Predicting and forecasting the future water resources information in advance is an important factor for improving the dispatching and utilization of reservoir control, ensuring the safety of projects, supplying water rationally and maximizing the economic benefits. To this end, we now make a forecast of the water resources information of Nanwan Reservoir in 1991 and put forward suggestions on water supply regulation:
