基于Budyko方程的小理河流域径流响应研究
Study on runoff response in Xiaolihe basin based on Budyko equation
摘要
Abstract
The impact of environmental changes on runoff is comprehensive, and it is necessary to quantitatively distinguish the contribution of climate changes and human activities to runoff.In this paper, the precipitation, potential evapotranspiration and runoff in Xiaolihe basin were studied.The Mann-Kendall method was used to analyze the trends of the hydrometeorological elements above, the sequential clustering method and sliding Ttest were used to diagnose runoff abrupt change points, and the Budyko equation was used to quantitatively calculate the impact of climate and human activities on runoff changes.The results showed that runoff in Xiaolihe basin has a abrupt change point in 1988;compared with the multi-year average runoff depth from 1978to 1997, the annual runoff from 1998to 2010had a decrease of 7.06mm, and human activities lead to a reduce of 13.7mm, while climate changes resulted in an increase of 6.64mm.By comparing the results by the method for the sloop change ratio of cumulative quantity to Budyko equation, it is proved that both conclusions are similar, that human activities are the main reason leading to the decrease in runoff in Xiaolihe basin, and that the quantitative analysis of Budyko equation in Loess Plateau region is applicable.关键词
