摘    要:针对河川径流时序所具有的非线性与非平稳性特征,运用消除趋势波动分析法(Detrended Fluctuation Analysis,DFA)对长江上游控制性水文站—宜昌站1878~2001年的月均流量时序的演化特征进行了研究,以揭示该流域河川径流的长程相关性及其内在规律性。结果表明:长江上游河川径流时序波动具有长程相关性,且其标度指数具有显著的区域性,即在短时间尺度上具有强烈的正持续性,在长时间尺度上具有强烈的负持续性,且其正持续性至多可持续19个月,显示了长江上游流域产汇流系统演化具有复杂的物理机制。

关 键 词:长江上游  宜昌  径流  长程相关性  DFA

Abstract:Xiabandi Water Control Project is located on the Pamirs under a severe natural condition; of which the construction characteristics are high altitude, strong seismic intensity, high excavating slope of dam abutment, deep overburden upon dam foundation, deeply embedded headrace tunnel, high tectonic stress, etc.the specific measures and methods adopted during the construction for dealing with the unfavorable construction conditions mentioned above are systematically described herein in the aspects such as dam foundation treatment, dam type selection, headrace tunnel supporting, rock burst control, construction of underground powerhouse, treatment of abutment slope, etc.
Keywords:Xiabandi Water Control Project  dam foundation treatment  asphalt concrete core wall  supporting of headrace tunnel  rock burst control  underground powerhouse  high slope
