摘要
为了提高抗旱应急管理能力,对区域降水量的波动设置一个可容忍的上下波动幅度,降水量波动超过设定的容忍幅度时,需要运用预留水量进行吞吐调节。依据不同调节方式,提出两种抗旱应急预留水量需求估测模型。以辽宁省为例,利用国家气象信息中心提供的辽宁省8个气象观测站近54年(1956-2009年)降水量数据,分别估测不同调节方式下抗旱应急预留水量需求量并进行了比较分析。上述方法为抗旱应急预留水量需求估测提供了新的思路,为合理配置应急预留水量奠定了重要基础,并且具有可操作性。
In order to improve drought emergency management, this paper sets a tolerable range of precipitation fluctuation. When fluctuation value exceeds the tolerable range, emergency reserved water is needed for regulation. According to different regulation modes, two models are put forward with corresponding constraints. Taking Liaoning Province for example, according to time series of annual precipitation from 8 weather stations in this province from 1956 to 2009 supplied by National Meteorological Information Center, drought emergency reserved water demand is estimated and compared between two control modes. The method gives a new thought to estimate reserved water demand for drought emergency and lays a foundation for allocating drought emergency water with operation ability.
