摘要: 基于1959~2006年乐昌站、犁市()水文站的逐月实测降雨和径流资料,采用年内分配不均匀系数、变差系数等指标分析降雨和径流的年内分配、年际变化特征,并使用线性趋势法分析降雨、径流及径流系数的变化趋势。结果表明:变化环境下,武江流域降雨、径流年内分配不均匀系数有所增加,径流的年际变化大于降雨,径流系数呈增加趋势,流域产流能力增强。

Abstract: Based on the measured monthly average rainfall and runoff datas of the Lechang and Lishi hydrological station in the Wujiang River basin during 1959-2006, the nonuniformity coefficient in annual distribution, coefficient of variation and other indicators were calculated to analyze the characteristic of annual distribution and inter-annual variability. And the linear tendency was used to analyze the change trends of rainfall, runoff and the runoff coefficient. The results showed that, under the changing environment, the nonuniformity coefficient in annual distribution of rainfall and runoff were on the rise, the annual change of runoff was bigger than that of rainfall, the runoff coefficient showed an upward tendency, river runoff capacity became stronger.
