摘要
Abstract
Based on the the series of natural river runoff data from the main river control stations in Jiaozuo City from 1956 to 2016,the Mann Kendall trend test method and 5-year moving average hydrograph method were used to analyze the evolution trend of natural river runoff in Jiaozuo City.The results showed that from the 1950s to the 1970s,the natural river runoff showed a significant decrease trend,while from the 1980s to the present,the trend of runoff increase and decrease has not been significant.Over a long period of time,the trend of natural runoff changes is basically consistent with precipitation.In recent years,human activities have further intensified the impact of changes in underlying surface conditions on the confluence character of the watershed.关键词
