摘要
根据水文年鉴和有关记载,统计了1958～2010年大兴安岭地区冰上累积雪深和雪水当量,利用线性相关分析、Mann-Kendall、小波分析等方法对冰上积雪和雪水当量参数的时空变化进行了分析,同时对其变化趋势和特征进行了检验,揭示了大兴安岭地区冰上累积雪深和雪水当量变化规律与QBO、太阳黑子、PDO振荡规律存在相关性,进一步浅析了其变化反馈机制。
This paper sifts the big ice tired the deep and consume the snow melt equivalent from hydrological statistics yearbook and relevant records from 1958 to 2010 in Daxinganling. The change of snow cover and snow melt equivalent over both time and space are analyzed and the changing trends and characteristics are tested by linear correlation analysis, Mann-Kendall, wavelet and so on. It also reveals the correlation and the feedback mechanism of both the variation of snow depth, snow melt equivalent and the QBO, macula, PDO in Daxinganling.
