鄱阳湖流域降雨量时空变异规律研究

Study on the principle of rainfall temporal and spatial variations in Poyang Lake catchment

中文摘要英文摘要

本文对鄱阳湖流域内606个雨量站点,1978-1982年连续5年的年均降雨量、年最大降雨量和年最小降雨量资料进行了时空变异规律研究。研究发现:1982年年均降雨量较1978年有显著增加,年均降雨量系列在东西方向没有明显的变化趋势,在南北方向存在明显的抛物线变化趋势;通过空间插值发现:克里金(Kriging)插值法较距离权重反比法(IDW)有更高的插值精度。

In this paper, the principle of rainfall temporal and spatial variations were studied by using mean annual rainfall, maximum annual rainfall and minimum annual rainfall series from 1978 to 1982 at 606 gauges in Poyang Lake catchment. Results showed that: mean annual rainfall in 1982 was remarkable increase than that of 1978, mean annual rainfall series had no notable trend on west-east direction while parabolic trend existed on the same direction. By spatial interpolation, it was found that Kriging method had a higher precision than IDW method.
