摘要
基于水文随机分析方法中的跳跃原理,采用有序聚类分析法确定广西澄碧河水库汛期入库流量跳跃点为5月中旬与8月下旬,并用游程检验法对其跳跃成分进行显著性检验,确定前汛期为4月上旬至5月中旬,主汛期为5月下旬至8月下旬,后汛期为9月上旬至10月下旬。采用轮次分析原理对分期结果进行合理性检验,认为该分期结果合理。该方法具有计算便捷、识别精度高以及分期结果可靠等优点。
On the basis of the shift or jump principle of hydrologic stochastic analysis method,orderly clustering analysis method was adopted to decide Guangxi Chengbihe Reservoir flood season staging that the jump points were in the middle of May and late August,and run length testing method was used to do significant testing of jump component. Reaching a conclusion that the antecedent flood season is from early April to mid May,main flood season is from late May to late August,and the late flood season is from early September to late October. And then rounds analysis principle is used to test the staging results,showing that the staging result is reasonable. This method has the advantages of convenient calculation,high precision of recognition and reliable staging result etc.
