梧州市近30年降雨量时空变化分布分析
Analysis of Temporal and Spatial Distribution Patterns of Rainfall in Wuzhou in Recent 30 Years
摘要
Abstract
The interpolation effect of Kriging,IDW,Spline and Trend method is analyzed,and the suitable ones have been chosen for the analysis of the rainfall in Wuzhou,and the distribution characteristics of time and space change of seasonal and annual rainfall in wuzhou are studied.Results show that:Kriging,IDW and Spline method are good for spatial interpolation for seasonal and annual rain-fall.rainfall decreasesfrom north to south in spring;rainfall decreases from northwest to southeast in summer;rainfall decreases from south,northwest to central in autumn;rainfall decreases from north and south to central and eastern in winter;annual rainfall decreases from north and south to west,southeast.most of Wuzhou rainfall increasesin spring;rainfall increasesin Wuzhou in summer;rainfall in-creasesin most of Wuzhou in autumn;rainfall increases in most of Wuzhou in winter;annual rainfall increases in most of Wuzhou.rain-fallrelatively decreases in the 80s of the 20th century;rainfall in the 90s of the 20th century is more than that in the 80s;rainfall in the 10s of the 21st century is less than that in the 90s of the 20st century.关键词
