摘要
漓江上游产水情况影响着漓江桂林～阳朔河段的水资源量变化。桂林水文站是漓江上游的关键界面,利用桂林水文站近30年的逐月径流资料,分成2个系列进行时间序列分析,运用Kendall秩相关检验、线性趋势回归检验法,对漓江流域上游的径流序列的变化规律进行研究,并发现近30年来,漓江水量总体上趋势平稳。
The water discharge of the upper reaches of Lijiang River affects the water resources of Lijiang River from Guilin to Yangshuo. Guilin hydrological station is the interface in the upper reaches of Lijiang river. The nearly 30 years＇ monthly runoff date from the station was divided into two series which are analyzed separately with time series analysis. In this paper, time series method such as Kendall rank correlation coefficient and linear trend regression test are used to study the regulation of the runoff series of the upper reaches of Lijiang river and find out that the trend of water quantity of Lijiang river is stable.
