Let (X,ρ,μ)dθbe a space of homogeneous type with d > 0 and θ∈(0,1],b be a paraaccretive function, ∈∈(0, θ]，︱s︱ < ∈, and a0 ∈(0, 1 be some constant depending on d, ∈ and s. The authors introduce the Besov space bBspq (X) with a0 < p ≤∞, and the Triebel-Lizorkin space bFspq(X) with a0 < p < ∞ and a0 < q≤∞ by first establishing a Plancherel-Polyatype inequality. Moreover, the authors establish the frame and the Littlewood-Paley function characterizations of these spaces. Furthermore, the authors introduce the new Besov space b−1 BPspq (X) and the Triebel-Lizorkin space b−1 FPspq (X). The relations among these spaces and the known Hardy-type spaces are presented. As applications, the authors also establish some real interpolation theorems, embedding theorems, Tb theorems, and the lifting property by introducing some new Riesz operators of these spaces.
