Land Use Planning Based on Regional Ecosystem Health Assessment—A Case Study of Beijing |

Abstract: |
Healthy regional ecosystem can continuously provide
ecosystem services, which is the basis of sustainable urban
development. At the same time, urban land use directly affects
its health status. Therefore, how to rationally plan urban land
use from a health perspective has become the focus of landscape
architecture and urban planning research. Taking Beijing as an
example, based on the land use types in 2007 and 2017, the CAMarkov model is used to predict the four land use scenarios of
natural development, rapid development, multi-objective protection
and forest construction in 2027, and a new method is proposed to
explore a healthier urban land use planning by using the regional
ecosystem health assessment framework, which includes the
physical and functional health indicators, to evaluate the land use
forecast. The results show that compared with the healthy state in
2017, the rapid development scenario in Beijing shows a negative
value. In other scenarios, it shows a good growth trend, especially
in the forest construction scenario. Adhering to ecological priority
and green development, intensive development of construction land
and strengthening forest construction can greatly improve the health
of regional ecosystems. |
