The invention discloses a tramcar ground section hedge plant arrangement structure which comprises a tramcar roadbed and two tramcar walking lines. Each tramcar walking line comprises a reinforced concrete rail bearing table, a tramcar rail, a prefabricated standard concrete component array, planting soil, hedge plants, turf, a pre-buried steel plate, guardrail stand columns, a comprehensive pipeline, a comprehensive pipeline plain concrete encapsulation and a water supply pipe. The prefabricated standard concrete component array comprises a plurality of prefabricated standard concrete components which are arranged in the walking direction of the tramcar track, each prefabricated standard concrete component is provided with a comprehensive pipeline installation groove and a water supply groove, the top of each prefabricated standard concrete component is provided with an embedded steel plate, and the guardrail stand columns are welded to the embedded steel plates. Intensive design is carried out, occupation of road resources is reduced to the maximum extent under the conditions that pipeline laying, hedge plant growth and smooth drainage are met, meanwhile the construction efficiency is greatly improved in a pre-production site splicing construction mode.
