Abstract: A new generalized two component Camassa-Holm system is derived via the energy variational approach. This system has two parameter which depend on the energy functional. The initial value problem is investigated. The local well-posedness is obtained when the initial density is away from vacuum. Taking advantage of the method of characteristics and the conservation laws we prove a blow up criteria. According to the blow up criteria, we can prove the finite time blow up result under some suitable condition. Moreover, we give some exact expression of traveling solutions. This is a joint work with Yuhui Chen, Wei Luo and Fang Yu.
