中文摘要：
以奎屯河为研究对象,综合利用滑动平均法、Mann-Kendal l秩次相关检验、Spearman秩次相关检验和线性回归法对奎屯河出山口站径流量变化趋势进行分析,同时对影响径流量的气象因子进行分析。结果表明：奎屯河径流量、降雨和气温呈显著增加的趋势,而蒸发有逐年减少的趋势;通过多元线性回归分析表明,影响径流增加的主要因素是降雨和气温,蒸发对其影响微弱。
英文摘要：
The changing characteristics of runoff and its influential factors in Kuitun river were analyzed by using the methods of accumulative anomaly analysis, M - K rank verification, Spearman rank verification and linear regression. The test results showed that annual runoff, precipitation and average air temperature in Kuitun River presented a tendency of increasing, yet the annual average evaporation was reducing. According to the analysis of muhifactorial regression, the main factors leading to the increase of annual runoff volume were precipitation and average air temperature, comparing to the minimal influence by annual average evaporation.
