研究流域水文水资源的演变规律,可为流域水资源开发利用和保护以及区域社会经济的可持续发展提供重要的决策依据。本研究以秃尾河流域出口水文站高家川站1956-2004年年平均流量和年降水量资料为主,对该流域径流和降水的趋势性和跳跃性进行了分析诊断,结果表明该流域降水的趋势性和跳跃性不显著;而径流具有非常显著的减小趋势,经多种方法综合诊断,最终确定了该流域径流在1978年发生跳跃变异,最后结合实际水文调查资料从成因上对结果进行了合理性论证。综合诊断有效地解决了单一检验方法检验结果可信度较差,多种检验方法检验结果不一致的问题,对复杂的时间序列变异点的识别与检验有一定的效果。
研究流域水文水資源的縯變規律,可為流域水資源開髮利用和保護以及區域社會經濟的可持續髮展提供重要的決策依據。本研究以禿尾河流域齣口水文站高傢川站1956-2004年年平均流量和年降水量資料為主,對該流域徑流和降水的趨勢性和跳躍性進行瞭分析診斷,結果錶明該流域降水的趨勢性和跳躍性不顯著;而徑流具有非常顯著的減小趨勢,經多種方法綜閤診斷,最終確定瞭該流域徑流在1978年髮生跳躍變異,最後結閤實際水文調查資料從成因上對結果進行瞭閤理性論證。綜閤診斷有效地解決瞭單一檢驗方法檢驗結果可信度較差,多種檢驗方法檢驗結果不一緻的問題,對複雜的時間序列變異點的識彆與檢驗有一定的效果。

Research on evolution of hydrology and water resources in river basin can provide an important decision basis for the utilization and protection of basin water resources and regional sustainable development of economy and soci -ety .In this study ,the watershed runoff and precipitation trends and variability are analyzed according to the annual flow and precipitation data in 1956 - 2004 of Tuwei River Watershed outlet station-Gaojiachuan station .The results show that the precipitation trend and variability is not obvious ,and the runoff decreased significantly .It is determined eventually that the jump variation of runoff occurred in 1978 by comprehensive diagnosis with various methods .The rationality of re-sults is reasoned according to its origin combined with actual survey .Comprehensive diagnosis effectively solves poor reli-ability for single test and inconsistency between various tests ,and has certain effects for identification and test to variation point of complex time series .
