A Study on the Ecological Balance Capacity of Hanoi Green Corridor

The “Hanoi Capital Construction Master Plan to 2030 and Vision to 2050” has been approved and implemented by the Vietnamese government since 2011 with the goal of channeling city development to become a sustainable capital in Asia. To achieve that goal, the green corridor has been established with four crucial roles, including: (1) to control the urban sprawl (2) to preserve the landscape and natural value (3) to be a logistics area for the central city (4) to consolidate the environment balance. However, different from the city green corridor in other countries, Hanoi green corridor embraces various high-density residential areas and new development projects, which has resulted in land use transformation. Therefore, the paper has two objectives, including (1) evaluating the ecological balance capacity of Hanoi green corridor for the whole city and (2) assessing the change of the afore-mentioned capacity since establishment due to city transition. The research methodology is to use the plant biomass calculation tool, combining with high-resolution satellite images in different years. The research result will quantify the ability to balance CO₂ in the air of Hanoi green corridor and its change, providing a scientific basis for adjustment of land use planning toward a sustainable city development.
