ABSTRACT: The current urban green space construction was
guided by a two-dimensional index evaluation system, resulting in weak
ecological benefits of green space. Green plot ratio (GPR), as a
three-dimensional indicator, can characterize the ecological benefits of green
areas and the ability of green areas to participate in the operation and
regulation of urban ecosystems. As an important component of urban green space,
the GPR index was added to the two-dimensional index evaluation system to optimize the green space, which can promote
the development of low-carbon, healthy and ecological green space. Based on the
research of 22 residential districts in the central city of Chongqing, the Leaf
area index (LAI) index of common native garden plants in Chongqing was formed
to improve the accuracy of green capacity index measurement in Chongqing. The
study also took the residential community of Sunrise City in Banan District of
Chongqing as an example, and carried out the optimization design practice from
four types of residential community green areas: green areas next to houses,
road green areas, concentrated green areas, and green areas attached to public
service facilities.
