Carbon Footprint Research of Landscape Engineering Based on Life Cycle Analysis — Take the Unoccupied Space Landscape Engineering of Wuhan Optics Valley Road (Optics Valley Road One — Liufang Road Section) for Example

Carbon footprint calculation has important guiding significance to carbon emission reduction, especially the carbon footprint research of landscape engineering based on life cycle analysis fully reflects the whole condition of carbon emission in the construction process and effectively guide the whole process conducted with low-carbon. This essay preliminarily analyzes the condition of carbon footprint of life cycle in the construction project of landscape engineering, provides corresponding calculating boundary and calculating method for four stages--planning and design, construction, maintenance management and refurbishment and demolition, and proposes to pay attention to reduce hidden carbon footprint in the stage of planning and design and construction management. The explicit carbon footprint is supposed be reduced in the stage of construction and maintenance management through comprehensive coordination and reasonable material selection. Finally, try to estimate detailed carbon footprint by combining with the project case of unoccupied space landscape engineering of Wuhan Optics Valley Road, which aims at discussing calculating method and parameter of carbon footprint of specific landscape engineering, knowing the condition of carbon emission of each process and providing reference for relevant construction to reduce carbon footprint more effectively in future.
