四种面雨量算法在伊犁河流域的适用性分析
Analysis on the Applicability of Four Area Rainfall Algorithms in the Yili River Basin
摘要
Abstract
Based on daily rainfall data from 200 meteorological stations in the Yili River Basin from May to September during 2019-2023,this study analyzes the precipitation distribution characteristics and calculates areal rainfall using four methods:the arithmetic mean method,inverse distance weighting,Kriging interpolation,and Thiessen polygons.The results indicate that:(1)Precipitation distribution is uneven,with more precipitation in the southwestern and eastern parts.The Bolbosong River receives the highest rainfall,while the Khorgas and Hassan Rivers show a"north-high,south-low"pattern.The Bolbosong and Gongnaisi Rivers exhibit decreasing precipitation from east to west.(2)Significant differences exist in the applicability of areal rainfall algorithms across sub-basins,with the arithmetic mean method performing best and Kriging worst overall.(3)The differences in algorithm applicability become more pronounced under varying precipitation levels(light rain,moderate rain,heavy rain,and rainstorm).(4)The Thiessen polygon method results show that the Bolbosong River has the highest daily and monthly areal rainfall values among all sub-basins,with most basins peaking in June for both monthly areal rainfall and rainy days.关键词
