摘要The solar flare occurred on April 2, 2001 is the biggest flare in 23rd cycle of solar activity, which is companied by a big solar proton event. We study this event by combining the observational results from spacecraft SZ2/XD and satellite ZY1/CBMC. SZ2 has the orbit with 400 km height and inclination of 42degrees, and ZY1 has solar-synchronous orbit and 780km to the Earth surface. The results show that after this flare ZY1/CBMC detected the flare particles in the polar cap region and XD observed an increase of energetic electron flux near the latitude 42degrees. Morphological analysis of the temporal and spatial variations of energetic particles after this flare indicates that particles in different regions have varied origins. Those in the polar cap region come from the Earth's open field lines and those in the auroral oval and mid-latitudes near 42degrees are particles of the Earth's outer radiation belt. Data analysis and comparison show that the intensity of the solar proton event is not proportional to the X ray flux of the related solar flare. The response of energetic particles in the near Earth space is not solely related with solar X ray intensity.
