【摘要】：針對云南2009年以來連續(xù)4 a干旱達百年一遇的極端水文事件導致273條中小河流斷流、413座小型水庫干涸,水源地庫塘蓄水困難,供需矛盾突出的現(xiàn)實,選取楚雄市九龍甸水源地鳳屯站1964~2010年降水監(jiān)測資料,采用小波分析、集中度與集中期分析、Mann-Kendall檢驗、R/S分析等方法,分析楚雄市降水基本特征、變化趨勢、變化周期、年內(nèi)分配、突變、未來趨勢變化等,以厘清九龍甸水源地的降水特征,為楚雄市水源地脆弱性診斷研究提供科學依據(jù)。分析結(jié)果對九龍甸水庫的來水預測、蓄水供水及運行調(diào)度提供策略具有十分重要的現(xiàn)實意義。
[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.
