Abstract：Research purposes: Hydrogeological parameter is one of the most important factors for project optimization design. Considering the generic parameter identification existing time consuming and unavoidable man-made error, the author applies genetic algorithm to identify the hydrogeological parameter to overcome the limitation of traditional method.
Research methods: Basing on the actual pumping test data measured in the field, inversion-analysis program is used which is based on the genetic algorithms to identify the hydrogeological parameters. The results obtained by genetic algorithms and two-pointes method are compared.
Research results: The results have indicated that two kinds of parameter inversion method can get the similar results.
Research conclusions: As one kind of optimization methods , the genetic algorithm is simple , universal and also has the characteristic of good adaptability and high efficiency on parameter inversion, and which can be widely employed to hydrogeological parameter inversion.
