Identification of Influencing Factors on Monthly Runoff
摘要
Abstract
Identification of influencing factors on runoff is a key to runoff forecasting,which could offer a scientific support for further study the evolution of runoff.This paper takes monthly runoff as an example and uses the data on monthly runoff and the average precipitation of the Shitouhe watershed from 1954 to 2007 to select the possible factors according to cause analysis,then uses the relevant probability,single correlation coefficient and Spearman coefficient to analyze correlativity,gets the main factors from the consolidated results of above analysis methods.The results show that runoff occurring in January and November is mainly affected by runoff of previous month,monthly runoff of March and December is mainly affected by the runoff occurring in advance of that two months.Runoff of February,April,July,August and October are affected by precipitation with previous monthly runoff.Runoff of May,June and September is mainly affected by the monthly precipitation.关键词
