Identifying and Setting of Natural Space Priorities Based on Multi-Ecosystem Services Capacity Index |

Abstract: |
In the case of limited spaces in the rapidly urbanized
areas, it is of great significance to identify ecological sources with
key landscape ecological functions and their protection priorities
for enhancing the level of regional multi-ecosystem services
and sustainable development. In this paper, the multi-ecosystem
service capability index (MESC index) of each natural space
were evaluated by the constructed coupling model. The results of
clustering analysis based on the index divided the natural spaces
into six priority grades. The higher the priority grade of natural
space is, the more important its function is, and the less difficult it
is to maintain or enhance the services, which also means that this
natural space should be identified as an important ecological source
and brought into the ecological network in the first place. The
method based on MESC index evaluation proposed here provided
a clear and repeatable framework and useful planning reference
information for the hierarchical management of natural spaces. |
