摘  要:
漳泽水库是山西省长治市农业灌溉和城市、工业用水的重要水源。利用多种指标对漳泽水库1956-2008年53年年径流进行年内、年际变化特征分析。采用线性回归、五年滑动平均、累计距平、五点三次平滑和七点二次平滑方法对漳泽水库的径流量变化趋势进行分析。同时,采用滑动t检验、山本(Yamamoto)法对漳泽水库进行突变分析。结果表明:漳泽水库径流年内分配不均匀,径流量集中在7-9月,年际变化较大,53a来,漳泽水库年径流量总体上呈减少的趋势,并且在1976年发生了一次显著性突变。

摘  要:
Zhangze reservoir is an important water source for agricultural irrigation,urban and industrial water use of Changzhi City,Shanxi Province.In this paper,based on the runoff data of 53 years from 1960 to 2008,a variety of indicators are adopted to analyze the inter-annual and annual distribution laws of the runoff in Zhangze reservoir.Five methods,including the linear regression,5-year moving average,cumulative anomaly,the smooth of 3 times with 5 years and seven secondary smoothing,are used to analyze the change trend of annual runoff processes.Meanwhile,the moving t test method and Yamamoto method are used to analyze the mutation characteristics.The results show that the annual distribution of the runoff in Zhangze reservoir is uneven and the runoff is concentrated at July to September;the inter-annual distribution of the runoff changes greatly,has a decreasing trend as a whole for the past 53 years,and there was a significant mutation in 1976.
