论水库旱限水位分期控制的必要性与计算方法探讨

Necessity and Methods for Reservoir Seasonal Drought Control Water Level

摘要: 为应对日益频繁的干旱问题，新生了旱限水位理念。通过与水库死水位和消落水位相对比，阐述了水库旱限水位的内涵。通过类比水库汛限水位，论述了水库旱限水位分时段控制的必要性；采用三峡水库和隔河岩水库常规调度结果，论述了旱限水位的分时段控制应主要考虑水库低水位时段并综合水库入流和需水特征参数予以选取。依据这一原则，提出了开展旱限水位分期控制的计算方法。

Abstract: Similar to the reservoir flood control water level, the drought control water level, though a new concept, is very important for reservoir drought relief operation. The definition and the importance of the drought control water level has been introduced and discussed. Some theoretical methods on the drought control water level, including the necessity of the seasonal control and how to determinate the seasonal values, have been pointed out. The reservoir drought control water level can be a guide for the further improving the management of drought, which also plays an important role in water supply engineering programming and water resources optimal allocation.
