目前 ,黑河干流水量调度年为上年的 11月 11日至本年度 11月 10日。由于 10月 10日左右是中游冬灌期开始时间 ,至 11月 11日结束 ,冬灌期为 31天 ,冬灌期将调度年分割开来。在冬灌期实施水量调度 ,一是中游用水紧张 ,来水量也有限 ,难度很大 ;二是给中游地区会带来一定的损失。是否将调度年结束时间提前至冬灌前的 10月 10日 ,在冬灌前完成全年度的调度指标 ,即调度年为上年 11月 11日至本年度 10月 10日 ,较目前调度年结束时间提前1个月。针对这一问题进行探讨。
At present, the Heihe main stream water regulation year is from November 11 to November 10 this year. As about October 10 is the beginning of mid-winter irrigation period, to November 11 end, winter irrigation period is 31 days, the winter irrigation period will be divided into years. In the winter irrigation water regulation, the first is the water stress in the middle reaches, water is also limited, difficult; Second, to the mid-range will bring some loss. Whether to schedule the end of the year ahead of winter irrigation before October 10, before the completion of the winter irrigation schedule targets for the year, that is, the scheduling year for the previous year November 11 to October 10 this year, compared with the current scheduling end of the year ahead of schedule 1 month. To address this issue.
