摘要
采用五点滑动平均法及线性趋势分析法,对梅山水库流域1952-2011年降雨量的年际变化、年内变化、时空特征等进行分析。结果表明,近60年降雨量具有一定的周期性变化特征,年降雨量有减少的趋势,年内分布不均的状况持续加剧。
Based on the precipitation data from 1952 to 2011 in Meishan Reservoir Watershed, using five sliding average method and linear trend analysis method, it mainly analyzed the characteristic of precipitation variability, the temporal and spatial characteristics, annual changes. The results showed that the precipitation in this 60 years have some of the periodical change characteristics, the annual rainfall series exist the reducing trend and the uneven distribution of year is increasing.
