Evolution of Green Space and Its Impacts on Urban Expansion in Mountainous Cities—The Case of Chongqing |

Abstract: |
This paper analyzed the evolution of urban green space in Chongqing central area
from 2006 to 2011. The effects and constraints of green space planning on urban expansion
were further discussed. The results showed that the preservation of vegetated mountainous
and hilly areas resulted in polycentric urban structure in Chongqing, which was regarded as
one of promising urban forms. However, a large amount of green space was encroached by
modern urban development. This development led to fragmentation and isolation of existing
green space, thereby imposing constant challenges on green space planning. Fortunately, some
green parks and squares newly increased in the suburbs, which were largely converted from
agricultural land. The inherent contradiction between urban development and green space
protections called for in-depth researches during mountainous settlement development. |
