本文将结合实际情况,对水文干旱进行简要综述,并以此为基础,研究讨论考虑径流调节与不考虑径流调节两种具体情况下的水文干旱的分析方式。使用人工手段,使其生成径流的系列。通过实际的水的需求量,分析截断水平生产干旱情况,从而得到天然水文干旱的分析统筹特点。这其中主要包含了不同情况下的水文干旱的不同频率、耗费时间、整体强度等。通过对径流调节情况分析,总结出水文干旱的统计特征。综合两种不同的情况,对水文干旱的统计特点进行思考,从而得出水库径流调节对水文干旱的影响。
In this paper, a brief review of hydrological droughts will be made on the basis of the actual situation. Based on this, we will discuss the hydrological and drought analysis methods in both specific cases of runoff regulation and runoff regulation. Use artificial means to make a series of runoffs. By analyzing the demand of actual water and analyzing the situation of cutting off the horizontal production of drought, the analysis and co-ordination of natural hydrological drought can be obtained. This mainly includes different frequencies of hydrological drought in different situations, time-consuming, overall intensity and so on. Through the analysis of runoff regulation, the statistical characteristics of hydrological drought are summarized. Based on two different situations, the statistical characteristics of hydrological drought are considered, and the impact of reservoir runoff regulation on hydrological drought is drawn.
