Disclosed is an aircraft parameter mapping system and method based on supporting vector machine and multiple regression. The system comprises a data input module, a parameter mapping check module, a parameter mapping verification module, a parameter mapping confirmation module and a mapping display module. Through few aircraft-scheme-related response parameters and self-varying parameter data sample pairs, a parameter mapping relation between the response parameters and the self-varying parameter data sample pairs is established; data samples of part of the response parameters in the data sample pairs are allowed to contain errors or noise, a high-precision calculation model is replaced with parameter mapping to engage in optima design of aircraft overall schemes, the requirement for quickly acquiring optimal aircraft overall schemes is met, and optimizing efficiency is improved.
