Variation characteristics of runoff in upper reaches of Lijiang River Basin
摘要
Abstract
Based on the measured runoff data of Guilin,Darongjiang and Lingqu hydrological stations in the upper reaches of the Lijiang River basin,this paper analyzes the annual and inter-annual runoff variation using statistical analysis method and Mann-Kendall nonparametric test. The results show that the annual distribution of runoff in the upper reaches of the Lijiang Riv-er basin is uneven,and the non-uniformity coefficient ranges 0.73 ~ 0.78. The inter-annual variation of runoff is relatively uniform,and the uniformity of the three stations is similar,the variation coefficient ranges 0.19 ~ 0.21,and the annual extreme ratio ranges 2.53 ~ 2.69. The runoff of the upper reaches of the Lijiang River basin has an increasing trend from 1954 to 2016 as a whole and the runoff at Guilin hydrological station mutated in 1991,Darongjiang hydrological station in 1958 and 1963,and Lingqu hydrological station in 1968.关键词
