The invention provides a space debris-oriented space-based optical observation initial orbit association method and system, and the method comprises the steps: 1, obtaining and processing imaging data through a space-based optical observation platform, and obtaining the short arc observation data of an unknown target; 2, performing numbering management on the acquired short arc observation data according to time; 3, performing short arc initial orbit determination on the acquired short arc observation data, storing the original short arc observation data and serial numbers, and processing the obtained initial orbit; 4, performing coarse association by utilizing the processed initial orbit, and if the association is successful, executing the step 5; and 5, performing fine matching by using the processed initial orbit and original short arc observation data, and if the matching is successful, storing the associated orbit determination information. According to the method, the initial orbits which are not cataloged can be accurately associated, and the method can be universally suitable for space debris-oriented space-based optical observation initial orbit association.
