中文摘要	研究降雨与降雨侵蚀力的时空变化特征及其原因对流域土壤侵蚀监测、评估、预报和治理具有重要意义。以干旱半干旱的渭河流域为研究对象,采用Mann-Kendall检验分析了降雨与降雨侵蚀力的变化趋势;采用启发式分割法对流域降雨量与降雨侵蚀力进行了变异诊断;采用交叉小波分析探究了ENSO(厄尔尼诺南方涛动)、北极涛动、太阳黑子与降雨以及降雨侵蚀力的联系。结果表明:(1)降雨和降雨侵蚀力均呈下降趋势;(2)华山站和西吉站的降雨量存在变异点,华山站和临洮站的降雨侵蚀力存在变异点,渭河流域部分站点的雨量和雨力的一致性被破坏;(3)ENSO、北极涛动、太阳黑子可能会影响降雨与降雨侵蚀力的产生,其中太阳黑子的影响最强,ENSO次之,北极涛动最弱。研究结果有助于指导渭河流域黄土高原地区的农业生产、水土保持建设和生态修复等工作。
英文摘要	The study about the temporal and spatial variation characteristics of rainfall and rainfall erosivity and theirs causes was significant to monitor,evaluate,forecast and govern local soil erosion.The Wei River basin,a typical arid and semi-arid area in China,was selected as a case study.The change trends of rainfall and rainfall erosivity were analyzed by Mann-Kendall test.The heuristic segmentation algorithm was employed to detect the mutation points of the rainfall and rainfall erosivity in the Wei River basin.The crosswave analysis method was used to explore the relationship between ENSO (El Nino-Southern Oscillation), Arctic Oscillation,Sunspot and rainfall as well as rainfall erosivity.Results indicated that:(1)Rainfall and rainfall erosivity both showed downward trends;(2)There were change points in the rainfall series at Huashan and Xiji stations,and change points in the rainfall erosivity series at Huashan and Lintao stations,and these change points implied that the consistency of rainfall amound and intensity at some stations in the Weihe River Basin was destroyed;(3)All of ENSO,Arctic Oscillation and Sunspot variations showed strong impacts on the rainfall and rainfall erosivity variations,and the impacts followed the order of Sunspot>ENSO >Arctic Oscillation.The results would be helpful to guide the agricultural production,the construction of soil and water conservation and ecological restoration of the Weihe River basin.
