摘要： 由于水文现象的复杂性及其资料的有限性, 至今尚无法在理论上确定洪水峪量究竟属何种频率分布。目前选择线型均是依据实测资料, 以曲线与经验分布的拟合优劣作标准来确定线型。通过用四种频率线型, 对新疆天山北坡中小河流洪水进行拟合分析, 从11个站的拟合情况来看, 有9个站用P-Ⅲ型拟合结果最好, 占整个参加分析站点的82%, 因此, 可以认为P-Ⅲ型曲线较适应于新疆天山北坡河流洪水分析。

Abstract: Over a long period of time, both domestic and foreign hydrologists have studied the curve types of flood fre-quency. However, it can not be theoretically determined that what kind ol frequency distribution the peak dis-charge belongs to. In flood frequency analysis, all the estimated results, including the various statistical parame-ters, designed peak discharge of the various flood frequency and the selected cur tained based on the flood data collected during a short period. Thus,, the considerable enol ‘i nbvdnf testochatstic, calculated, and systematic erf fs exls o ccuring in the mid-smallstreans on the aoroden sloye f lefrequency are selected for fitting analysis of floods occurring in the mid-small strean Tianshan Mountains. The fitted results are ideal at 9 hydrometric stations among 11 in total.

Key words: flood, curve type of frequency distribution, Xinjiang, North slope of Tianshan
