摘要
采用极值比和变差系数分析桂林市青狮潭水库1958-1995年入库径流量的年际变化特征,采用距平百分率法和Kendall秩次相关法分析入库径流变化趋势。分析表明,洪水期径流年际变化最剧烈,枯水期径流年际变化最小;年径流、雨期径流、洪水期径流和枯水期径流均呈增加趋势,但趋势不显著。
The annual change characteristics of inflow runoff into Qingshitan reservoir during 1958 - 1995 years is analyzed with the extreme ratio and coefficient of variation in this paper. And the anom-aly percent method and Kendall rank correlation method are used to study the change trend of incom-ing runoff. The results indicate that the annual runoff change of the flood period runoff is most une-venly. Annual runoff, rain period runoff, flood period runoff and drought period runoff all appear an increase trend, however, the change trends are not obvious.
