GREEN CORRIDORS LAND VALUE FUNCTIONS STRUCTURE
Combined with existing
landscape resources, the
green system is
composed of a north-
south axis connecting
Phase 1 and Phase 2, a
major east-west axis, and
several minor axes.
The land is divided into
different zones with
various land values
according to the
surrounding condition.
Different functional
groups (commercial,
residences, tourism island,
etc.) are arranged to meet
the needs of city
development while
maximizing the value of
the land.
According to the land
value, functions, such as
tourism and leisure, the
