河流水沙变化直接反映流域的生态环境状况和土壤侵蚀程度。为探讨南方典型水土流失治理区水沙变化特征及其驱动机制
以汀江流域长汀段1982年1月至2014年12月径流、输沙数据为研究对象
采用CEEMDAN法、Mann-Kendall检验法、Pettitt检验法及构建水沙关系模型分析水沙的变化特征
通过双累积曲线法定量研究降雨和人为活动对水沙变化的贡献率。结果表明:(1)汀江流域长汀段降雨和径流呈不显著减小趋势
输沙率显著下降(p<0.01)。径流与输沙的周期性及变化趋势不同步。(2)汀江流域长汀段输沙状况在2000年发生突变(p<0.01)
突变后径流含沙量降低
水沙关系曲线的来沙系数显著减小。(3)自2000年后
长汀段径流和输沙总量均减小
其中人为活动对径流变化的贡献率为68%~81%
对输沙变化的贡献率为90%~98%
人为活动中以封禁治理、生态林草等为主的水土保持措施是输沙量减少的最重要原因。
The changes of river runoff and sediment directly reflect the ecological environment and the degree of soil erosion in the basin. In order to explore the variation characteristics of runoff and sediment and its' driving mechanism in the typical soil erosion control area in South China
the runoff and sediment data of Changting section of Tingjiang River Basin from January 1982 to December 2014 were taking as the research object
and the CEEMDAN
Mann-Kendall trend test
Pettitt test and water sediment relationship model were used to analyze the variation characteristics of runoff and sediment. Meanwhile
the double accumulation curve was used to quantitatively study the contribution of rainfall and human activities to the changes of runoff and sediment. The results showed that:(1) The rainfall and runoff in Changting section of Tingjiang River Basin showed no significant decreasing trend
while the sediment rate decreased significantly (p<0.01). The periodicity and trend of runoff and sediment were not synchronous. (2) The sediment transport rate in Changting section of Tingjiang River basin changed suddenly in 2000 (p<0.01). After 2000
the runoff sediment concentration decreased and the inflow sediment coefficient of water sediment relationship curve decreased significantly. (3) The total amounts of runoff and sediment in Changting section decreased after 2000. The contribution rate of human activities to the change of runoff was 68%~81%
and the contribution rate of human activities to the change of sediment was 90%~98%. In human activities
the implementation of soil and water conservation measures dominated by banning management and ecological forest and grass construction were the most important reasons for the reduction of sediment.
