Abstract
Based on the measured data of 63 a from 1960 to 2022 at Baoqiao Hydrological Station,the control station in the lower reaches of Changhua River in Hainan,statistical methods such as linear trend analysis,R/S analysis and wavelet analysis are used to study the variation trend and periodic characteristics of runoff in the lower reaches of Changhua River.The results show that the runoff series in the lower reaches of Changhua River presents a weak downward trend on the whole,and there are frequent conversions between rise and fall in the local variation process.The runoff variation does not have a single continuous trend,but presents the fluctuation characteristics of multi-time scale nesting,among which about 10 months is the main period,showing obvious periodic fluctuation,and the variation trend of long time scale over 30 months gradually tends to be stable.The research results can provide reference for the optimal allocation and efficient utilization of water resources in the lower reaches of Changhua River under the background of Hainan Free Trade Port.关键词
