| Abstract: |
| Integrated management of ecosystem services is an important
way to ensure urban ecological security and optimize the spatial pattern
of national territory. With scarce ecological space, high pressure on
ecological environment, and diverse needs of residents, the central urban
area was confronted with a strong spatial differentiation between the
supply and demand of ecosystem services and complicated ecological
management. Therefore, the quantification of urban ecosystem service
supply and demand, and identification of spatial distribution differences
between ecological supply and residents' demand, is an important way
to enhance the efficiency of ecosystem service supply, and also a key
to supporting scientific planning and management of urban land use. In
this study, based on ecosystem services supply-demand ratio, the supply
and demand of seven ecosystem services, namely water conservation,
cooling effect, rainfall regulation, carbon sequestration, soil conservation,
biodiversity protection, and recreation, in the central urban area of Guilin
were measured as an example. The supply-demand bundles of ecosystem
services were identified by cluster analysis. Coupling supply-demand
matching and imbalance zones and ecological protection zones, and
three levels of ecological conservation zones and two types of restoration
zones are delineated. Based on the zones of ecological characteristics and
the supply-demand of ecosystem services, the grading and classification
management and control guidelines were proposed. This study can provide
a reference for urban planning and management of ecological space. |
