摘　　要：以黑河金盆水库为研究对象，以1954—2007年的入库径流数据为数据源，采用游程理论、模比系数变差差积对金盆水库的径流年际特征以及径流年内分布特征进行了研究。结果表明，黑河金盆水库年际径流丰枯变化剧烈，最大年径流量与最小年径流量相差6倍以上；1991年以后。入库径流呈现明显的下降趋势，17年间枯水年占82％以上，未出现连丰年，可以得出金盆水库目前正处于枯水期，易发生少水事件，易发生连枯现象；在年内径流分布方面，径流分布表现出明显的季节特点，65％以上的径流集中于夏季，冬季仅有8％的径流。Taking Hei River-Jinpen Reservoir as study object, using 54 years （ 1954 - 2007） runoff data to analyze the interaunual and intermonthly variation characters of Jinpen Reservoir with runs theory and modulus coeffificient residual mass diagram. The research shows runoff of Jinpen Reservoir has a violent swing in inter-annual variation; the maximum runoff is 6 times of the minimum runoff. After 1991, the runoff shows a decreasing trend dramatically. From 1991 to 2007, there are 13 low flow years in 16 years, the ratio is above 82% ; and there is no continuous abundant year in this period. It means Jinpen Reservoir is experiencing long term low flow year, it is easy to occur drought at pres- ent and in the not-so-distant future. Another character is seasonality, according to data analysis, there are more than 65% runoff generated in summer; the winter runoff is only 8%.
