在防汛抗旱、防灾减灾工作中,为了更好地开展对毕节倒天河水库的调度和安排,对水库集雨区的边界、位置、集雨区相对于贵州省毕节市天气雷达的位置等信息进行分析、调研和整理,形成精确的电子数据信息,为今后通过气象雷达观测信息分析水库水量增加情况,实现水库蓄水用水情况的调度管理开展基础性工作。结合实际需要建立思路和做法,提出集雨区边界的划法和原则,确定集雨区在毕节市天气雷达图中位置的确定步骤,为后期开展同类工作具有很好的指导意义。
In the flood control and drought relief and disaster prevention and mitigation work, in order to better carry out the dispatching and arrangement of the inverted Tianhe Reservoir in Bijie, the boundary and location of the rainwater catchment area of the reservoir and the location of the rain catchment area relative to the weather radar in Bijie of Guizhou Province Carry out analysis, research and collation to form accurate electronic data information, and carry out basic work for the future analysis of the increase of reservoir water volume through meteorological radar observation information and the realization of reservoir water storage management. Combining the actual needs of the ideas and practices to establish rainwater drawdown and the principles of the border to determine the rainwater catchment in Bijie weather radar map to determine the location of the steps for the latter to carry out similar work has a good guiding significance.
