Study on the Life-cycle-based Carbon Balance for Lanzhou Micro-park
As a kind of urban green space,micro parks are of great value in achieving the goal of"carbon neutrality".In recent years,a number of micro parks have been built and opened in the Chengguan District of Lanzhou,providing recreation and entertainment services to the public.However,it is unclear whether the carbon emissions generated during construction can be quickly absorbed by self-generation,so a life-cycle carbon balance calculation of the micro-park was made.The results show that it will take 40.8 years to achieve carbon balance for the Yuchikou Micro Park and 5.4 years to achieve carbon balance for the Donggang West Road Micro Park.This indicates that the micro parks consume a large amount of energy during the construction process,resulting in high carbon emissions and low ecological benefits.A comparative analysis based on the calculated results reveals that the main factors affecting its carbon balance are transportation distance,green space ratio,selection of landscape materials,and complexity of the construction process.Accordingly,further optimization strategies were proposed for the construction content and process.
