摘　　要：根据金沟河出山口一带1955～2008年的观测资料，对金沟河流域的径流与洪水特征进行了分析和阐述。分析认为：流域内的冰川是径流的主要补给源，影响径流年际、年内变化的主要因素是降水和气温，径流年内分配集中在6-8月，径流过程略滞后于气温和降水过程。金沟河径流的年内分配不均，多年平均最大月径流量是最小月径流量的16．3倍；径流的年际变化相对稳定，径流系列的年际变差系数Cv值为0．14。The article According to the Gold River area in 1955 - 2008 the observational data, analyzed and explained the river of Gold basin ofgold and flood nmoff characteristics, analysis consider： Basin glacier runoff are the main supply source, the impact of runoff years, the years are a major factor in changes of precipitation and temperature, runoff during the year are allocated to the 6 - 8 months, slightly lagging behind the runoff process temperature and precipitation process. Gold River runoff years the uneven distribution of the largest multi- year average rtmoff on nmoff are the smallest on the 16.3 times; rtmoff interannual variability is relatively stable, inter - annual runoff series of coefficients of variation Cv value of 0.14.
