The invention provides polymer-based vegetation concrete and a preparation method thereof. The polymer-based plant-growing concrete is prepared by mixing a permeable high-molecular polymer and gravel aggregate, the mass ratio of the permeable high-molecular polymer to the gravel aggregate is (3-6): 100; the permeable high-molecular polymer is prepared by mixing a group A material and a group B material at normal temperature; the material group A is prepared from special polyether polyol, a polyoxyethylene nonionic surfactant and a flame retardant tris (1-chloro-2-propyl) phosphate; the material group B is prepared from a plasticizer and polymerized isocyanate; the volume ratio of the material group A to the material group B is 1: 1. The polymer-based plant-growing concrete prepared by the invention is light in weight and high in porosity, and the pH value range is suitable for the growth of most plants. 本发明提供一种聚合物基植生混凝土及其制备方法。一种聚合物基植生混凝土，由渗透性高分子聚合物和碎石骨料混合制成；所述渗透性高分子聚合物和碎石骨料混合制成的质量比是3-6:100；所述渗透性高分子聚合物由A组材料和B组
