The ground-state phase diagram of the one-dimensional Kondo lattice model with an anisotropic exchange is investigated. Four different phases are identified, two types of N6el phases, the Haldane phase, and the Kondo spin liquid phase. The boundaries between these phases are determined by using mapp
