Summary:The invention relates to a space optical communication system based on a dynamic-adjustment optimal transmitting mode combination. The space optical communication system comprises an atmosphere turbulence intensity detection device, a mode dynamic adjustment device, a multipath LG mode generating device, a multipath LG mode modulation transmitting device and a multipath LG mode receiving detection device, wherein the atmosphere turbulence intensity detection device obtains an atmosphere turbulence intensity of an atmosphere channel; the mode dynamic adjustment device selects an optimal LG beam mode combination with the largest frequency efficiency under the current atmosphere turbulence intensity from different LG beam mode combinations by employing an optimal mode combination selection algorithm; the multipath LG mode generating device generates a multipath LG beam based on the optimal LG beam mode combination; the multipath LG mode modulation transmitting device modulates radio frequency signals based on th
