摘要
为了分析研究东江流域径流的演变规律,为流域的水资源可持续发展提供依据。采用模糊带权马尔科夫链原理,累积距平曲线一滑动t检验联合识别变点法,坎德尔(Kendall)秩次检验法等3种,对东江(博罗站)1963-2005年长系列径流序列进行分析。结果表明:预测2004为偏枯,2005年为正常年份;径流突变发生在1974年;径流年际变化不大。说明东江流域径流序列基本趋于稳定不显著增长趋势。
The runoff variation law of Dongjiang was studied for the basin's water resource sustainable development. Using the weighted and fuzzy Markov's Chain Model, the accumulation of Anomalies Curve-Slide T-test combined identified change site method, the Kendall way methods, the long series of runoff on Dongjiang (Boluo)River in 1963-2005 were studied. The result showed: 2004 was semshort, 2005 was normal, the runoff mutation point was in the 1974, its'variation of interannual was little. The runoff on Dongjiang(Boluo)River was stable.
