【摘要】：针对云南2009年以来连续4 a干旱达百年一遇的极端水文事件导致273条中小河流断流、413座小型水库干涸,水源地库塘蓄水困难,供需矛盾突出的现实,选取楚雄市九龙甸水源地凤屯站1964~2010年降水监测资料,采用小波分析、集中度与集中期分析、Mann-Kendall检验、R/S分析等方法,分析楚雄市降水基本特征、变化趋势、变化周期、年内分配、突变、未来趋势变化等,以厘清九龙甸水源地的降水特征,为楚雄市水源地脆弱性诊断研究提供科学依据。分析结果对九龙甸水库的来水预测、蓄水供水及运行调度提供策略具有十分重要的现实意义。
[Abstract]:In view of the fact that 273 small and medium-sized rivers have been cut off, 413small reservoirs dry up, water storage in water source ponds is difficult and contradiction between supply and demand is prominent, the precipitation monitoring data of Fengtun Station, Jiulongdian Water Source Station, Chuxiong City, from 1946 to 2010 are selected, and wavelet analysis, concentration and intermediate analysis, Mann-Kendall test and R / S analysis are used to analyze the precipitation in Fengtun Station, Jiulongdian Water Source Station, Chuxiong City. The basic characteristics, changing trend, change cycle, annual distribution, sudden change and future trend change of precipitation in Chuxiong City are analyzed in order to clarify the precipitation characteristics of Jiulongdian Water Source area and provide scientific basis for the diagnosis of water source vulnerability in Chuxiong City. The analysis results are of great practical significance to the prediction of incoming water supply and the strategy of operation and operation of Jiulongdian Reservoir.
