摘要：
In this paper we develop a second order, positive preserving explicit-implicit numerical method for solving Keller-Segel system of degenerate type. The approximation is based on finite volume method and flux-limiter technique in space and explicit Euler method in time. In order to save computational time we use decoupling procedure for solving the discrete system. Numerical results are also presented.
