摘要
采用趋势分析、小波分析等方法分析了1951～2010年塔河流域8个气象站点气象资料及13个水文站1956～2009年的径流量及降雨资料,揭示了不同时间尺度下塔河流域降雨及径流量序列变化周期,阐述了气候变化与径流变化特征之间的关系。结果表明,塔河流域的径流量处于相对平衡状态、降雨与径流主周期相同,气候变化仍是影响径流量变化的重要因素。
Based on the meteorological data of 8 meteorological stations from 1951 to 2010 and the runoff and rainfall of 13 hydrologic stations from 1956 to 2009, the variation characteristics of climate change and runoff is analyzed by using wavelet analysis and trend analysis. The periodic oscillation of rainfall and runoff variation at different time scales are dis covered and the relationship between climate change and runoff variation is presented. The results show that the runoff of Tarim River Basin is in equilibrium; the rainfall and runoff have the same main period; climate change is an important fac tor for influence of runoff variation.
