摘要:
南水北调中线供水以来,确保供水任务的完成已成为丹江口水库仅次于防洪的重要目标。选取丰、平、枯水典型年,尤其是连续枯水年径流资料,基于丹江口供水调度规程,结合供水期不同来水保证率,以满足供水需求为前提,分析了丹江口水库不同来水条件下不同时期的库水位控制指标。在大部分枯水年,9~10月份水位需要蓄至165 m左右,才能完成供水。若遭遇设计枯水年,汛末水位需要蓄至166~167 m才能满足供水需求。而连续枯水年需要有1~2年水位蓄至正常水位,才能保证后期供水。结合防洪需求提出了丹江口水库的蓄水方案,供水保证率可提高10%左右。

Abstract: After the completion of middle line of South-to-North Water Project, the water supply task has become the second important goal only to flood control for Danjiangkou reservoir. As a precondition to meet the water requirement, based on the water supply dispatching rules and the different incoming water guarantee rates in water supply period, the annual runoff of wet, normal and low flow typical years, especially continuous dry years were selected to analyze the reservoir water level control index under different incoming water conditions. Water level needs to be stored up to about 165 m in order to complete the water supply during September to October in the low flow years. In the dry year, water level at the end of flood season needs to be stored up to 166 - 167 m to meet the demand for water supply. In the continuous dry years, water level needs to be stored up to normal water level for 1 - 2 years to ensure later water supply. Combining with the flood control requirement, a refilling operation scheme is suggested, in which the water supply guarantee rate can be increased about 10%.
