为有效防治流域土壤侵蚀、维护生态安全,基于九曲水流域1982—2019年逐日降雨数据,运用小波分析、交叉小波变换等方法分析了中雨、大雨、暴雨及年降雨侵蚀力的年际变化规律,并探讨了太阳黑子、厄尔尼诺—南方涛动(ENSO)、北极涛动(AO)及太平洋年代际涛动(PDO)对它们的影响。结果表明:(1)中雨、大雨、暴雨及年降雨侵蚀力的年际变化趋势均不显著(p>0.05),其变异系数(CV)分别为0.24,0.31,0.64,0.26,均属于中等变异。(2)不同量级降雨侵蚀力的周期变化差异明显,年降雨侵蚀力与暴雨侵蚀力均存在15~23年周期变化和19年主周期,二者联系更紧密。(3)年降雨侵蚀力和暴雨侵蚀力与太阳黑子、ENSO、AO、PDO均分别存在9~11,10~11,10~11,9~10年的显著共振周期,暴雨侵蚀力受太阳黑子、ENSO、PDO的影响大于中雨、大雨侵蚀力,大雨侵蚀力受AO的影响大于中雨、暴雨侵蚀力。研究成果可为赣南乃至我国土壤侵蚀预测预报与防治提供科学依据。
In order to effectively prevent soil erosion in the watershed and maintain ecological security
based on the daily precipitation data from 1982 to 2019 in Jiuqushui watershed
the inter-annual variation rules of erosivity of moderate rain
heavy rain
rainstorm and annual rainfall were analyzed by using wavelet analysis and cross wavelet transform
the influences of Sunspots
El Niño-Southern Oscillation (ENSO)
Arctic Oscillation (AO) and Pacific Decadal Oscillation (PDO) on them were discussed. The results indicated that:(1) The inter-annual variation trend of moderate rain erosivity
heavy rain erosivity
rainstorm erosivity and annual rainfall erosivity was not significant (p>0.05)
and the coefficient of variation (CV) was 0.24
0.31
0.64 and 0.26
respectively
which were all moderate variations. (2) The periodic variation of rainfall erosivity in different magnitudes was obviously different
the annual rainfall erosivity and rainstorm erosivity had a 15 to 23 years cycle and a 19-year main cycle
which were more closely related. (3) The annual rainfall erosivity and rainstorm erosivity had significant resonance periods of 9 to 11
10 to 11
10 to 11 and 9 to 10 years with Sunspot
ENSO
AO and PDO
respectively. The impact of Sunspot
ENSO and PDO on rainstorm erosivity was greater than that of moderate rain erosivity and heavy rain erosivity. And the impact of AO on heavy rain erosivity was greater than that of moderate rain erosivity and rainstorm erosivity. The research results could provide scientific basis for soil erosion prediction and prevention in southern Jiangxi and even China.
