  After considering the supernova shock effects, the
Mikheyev-Smirnov-Wolfenstein effects, the neutrino collective effects, and the
Earth matter effects, the detection of supernova neutrinos at China Spallation
Neutron Sources is studied and the event numbers of different flavor supernova
neutrinos observed through various reaction channels are calculated with the
neutrino energy spectra described by the Fermi-Dirac distribution and "beta
fit" distribution respectively. Furthermore, the numerical calculation method
of supernova neutrino detection on the Earth is applied to some other
spallation neutron sources, and the total event numbers of supernova neutrinos
observed through different reactions channels are given.
