中文摘要通过分析近40年来出现的ENSO事件对云南东川蒋家沟泥石流活动的影响可知,E1 Nino与La Niha对其的影响正好相反,且E1 Niho的影响大于La Nina的影响。E1 Niho年,泥石流年发生频次、径流量和输沙量偏少的概率均较大,泥石流活动减弱的倾向明显;La Nina年,虽有一定的对应关系,但不如E1 Nino年明显,且影响更复杂一些,总的来说,泥石流年发生频次、径流量和输沙量偏多或持平的概率较大。
英文摘要Using the observat ion data go tten from Dongchuan Debris F low Observat ion and Research Sta tion since
1965, the primary study on debris flow relat ive to ENSO event in Jiang jia Rav ine ism ade, and the fo llow ing conclusions
are draw n. ENSO event is one o f the factors a ffecting the activ ity of debris flow in Dongchuan. The impact
of E lN ino event on the debris flow in Jiang jia Rav ine is more serious than that of LaN ina even t during the recent
40 years. G enera lly, the E lN ino event may decrease the precipitation in summer season. The probability o f low
qrequency, low runo ff and low sed iment transform ation o f debris flow is grea ter. On the contrary, the LaN ina event
may increase the precipitation in summer season, and the impact of the event ismuch complicated and not so obv-i
ous. Then, the high frequency, high runo f,f h igh sedimen t transformat ion and norma lity of debris flow are predom-i
nan.t The f ind ings suggest that further research into the relationsh ip betw een ENSO event and the activ ity of debris
flow in Dongchuan would be w orthw hile
