摘要
收集北京市密云集水区半城子水库1990~2006年降水量和径流量,发现近年来径流量变化较大。采用Excel软件进行降水量和径流量的数据统计,SPSS软件进行降水量与径流量的相关分析,Excel软件进行回归分析,研究降水量与径流量的协同响应关系。结果表明,研究区降水量与径流量的相关性并不十分显著,径流量不仅受到降水量的影响,还受到其他因素的影响。
The precipitation and runoff in Banchengzi reservoir of Miyun in Beijing during 1990-2006 were collected,and it was discoveried that the change of runoff was big.Using Excel to count and using SPSS to make correlation analysis,and using Excel to make regression analysis,the cooperative response of precipitation and runoff was researched.The results showed that the correlation between precipitation and runoff was not significant in the area.The change of runoff was not only influenced by precipitation but also the other factors.
