We consider the perturbed system as the combination of unperturbed system and perturbed term according to the characteristic of the first order approximate conserved quantities, and we suggest a new method to obtain the first order approximate conserved quantities by three steps, first, we select a suitable method to obtain the conserved quantities I0 of unperturbed system , second, we calculate the influence of perturbed terms on conserved quantities I0, and finally we obtain the first order approximate conserved quantities of the system by using the characteristic of the first order approximate conserved quantities.
