建国以来,国家用于水利建设的投资已达千亿元,其中很大部分是修建灌溉工程。灌溉面积已从解放前的2.4亿亩增加到7.28亿亩。灌溉土地上生产的粮食占全国粮食总产量的2/3。实践证明,灌溉事业的发展为我国农业产量的稳定和持续增长提供了重要保证。但具体到水利部门来说,用于灌溉工程的投资经济效益价值量究竟如何?如何正确地进行计算,才能作出客观的定量评估,
Since the founding of the People’s Republic, the investment made by the state for water conservancy has reached 100 billion yuan, most of which is for the construction of irrigation projects. The irrigated area has increased from 240 million mu before liberation to 728 million mu. Irrigated land produces about two-thirds of the country’s total grain output.

However, specific to the water conservancy department, what is the value of the economic benefits of investment for irrigation projects? How to correctly calculate, in order to make an objective quantitative assessment,
