【摘要】：鉴于定量分析干旱预警水位有利于水库抗旱期的合理调度,提出水库干旱预警响应机制,探讨与之相对应的水库干旱分级预警水位计算方法和步骤,并以柴河水库为例,考虑预警期为6个月,在分析水库来水量、需水量的基础上,采用逐6月应供水量滑动计算确定柴河水库旱限水位为96.47m,干旱Ⅰ~Ⅵ分级预警水位分别为86.98、89.40、90.79、93.18m,据此绘制了柴河水库干旱分级响应预警图,可用于指导水库抗旱调度工作。
[Abstract]:In view of the fact that quantitative analysis of drought early warning water level is beneficial to the reasonable operation of reservoirs during drought resistance period, the response mechanism of reservoir drought early warning is put forward, and the corresponding calculation methods and steps of reservoir drought early warning water level are discussed, and the Chaihe reservoir is taken as an example. Considering the early warning period of 6 months, on the basis of analyzing the water quantity and water demand of the reservoir, The drought limit water level of Chaihe reservoir is 96.47 m and the water level of drought 鈪，
