我国已建成大型水库335座,中型水库2367座,这些大中型水库工程大多具有防洪、灌溉、发电等综合功能,这些功能能否充分发挥直接影响工程的效益。怎样才能充分发挥其功能与效益,关键是对水的调度。特别是洪水的调度,而洪水调度的关键又在于如何处理好蓄与泄,大坝安全与灌溉、发电之间的辩证关系。但在这些关系的处理上,我 China has built 335 large reservoirs and 2367 medium-sized reservoirs. Most of these large and medium-sized reservoirs have comprehensive functions of flood control, irrigation and power generation. These functions can give full play to the direct impact on the project’s benefits. How to give full play to its functions and benefits, the key is to water scheduling. Especially flood regulation, and the key of flood regulation lies in how to deal with the dialectical relationship between storage and discharge, dam safety, irrigation and power generation. But in the handling of these relations, I
