摘要
By analyzing the observation data from Dongchuan Debris Flow Observation and Research Station and historical data from year 1965 to 1990 gotten from National Astronomical Observatories/ Yunnan Observatory, the responding of debris flow in Jiangjia Ravine to Solar Proton Flare is studied. The following conclusion can be drawn. Solar Proton Flare, as one of most important astronomical factors, affects the activity of debris flow in Yunnan. Generally, from 1965 to 1990, the more active Solar Proton Flare is, the greater the probability of high frequency and large runoff of debris flow is. On the contrary, the less active Solar Proton Flare is, the greater the probability of low frequency, small runoff, and low sediment transport of debris flow is.
