摘要
根据海河流域长系列水文气象资料,对流域内年径流量的演变趋势、突变特征和周期性规律进行分析,同时选取降水量和气温这两项重要的气候要素,建立海河流域年径流与降水、春夏气温的统计回归模型,计算未来A1B、A2和B1三种气候条件下的径流量,从而分析径流量对气候变化的响应。
Based on the hydrological and meteorological data of Haihe River Basin from 1956 to 2000 years,this paper analyzes the trend,jump features and periodic changes of Haihe River Basin runoff.The precipitation and temperature are selected as two important climate factors to establishment the statistical regression model of annual runoff,precipitation and average temperature of summer and winter over the same period.Runoff responses to climate factors under three different types of climate scenarios,A1B,A2 and B1,are also analyzed.
