摘要
通过分析南湾灌区灌溉用水资料,推求出灌溉定额与降雨频率的关系式,绘制不同降雨情况下不同灌溉面积的灌水量图及逐旬分配比例,可供灌区制定用水计划及水库调度运用参考。
The relationship equation of rainfall frequency and irrigation norm has been developed through analysis of the long series irrigation data of the Nanwan irrigation district. The irrigation water use graph and distribution rate of every ten days in different rainfall and irrigation area have also been drawn for referency of water use plan formulating and reservoir operation.
