摘要
本文利用长江宜昌站1955～1990年冬季径流量和气候资料,采用单相关系数法,挑选出了影响宜昌站冬季各月径流量的气候因子,并采用逐步回归方法筛选因子,建立预报模型,预报效果比较好,具有一定的实用价值。
Based on the data of winter runoff and climate data of Yichang station between 1955 and 1990,the paper picks out climatic factors which affect the monthly runoff of Yichang station in winter with single correlation coefficient method,selects factors with stepwise regression method and sets a forecast model the result of which is good.The model has the practical value.
