| 摘 要： | 选用宁夏六盘山区4个代表测站自建站以来至2007年的各月降水资料,用回归、周期和突变分析等统计方法进行分析,揭示了其多年时空变化规律.通过分析,得出了其季、年线性变化趋势和年变化周期及突变点,发现各区域降水存在着不同的变化规律,年降水均呈减少趋势,存在准14 a、11 a等变化周期,并发生了多次突变.

| Abstract: | Based on the monthly precipitation data measured by 4 representative meteorological stations in Liupan mountain area during the period of 1960-2007,the spatial and temporal distribution of precipitation was analyzed by using some statistical methods such as regression,periods and abrupt change analysis.The seasonal,annual trend of precipitation there and the primary cycles of annual precipitation were revealed.Results show that annual precipitation was decreasing and the primary cycles were fourteen and ele... |
