| Abstract: |
| Yuncheng City in Shanxi Province is located at the junction
of three provinces in the middle and lower reaches of the Yellow River,
and its landscape elements have complex components. The study of
ecological network patches and corridors in Yuncheng City is conducive
to the protection of the stability of the Yellow River ecosystem. In this
study, core patches with strong connectivity were identified based on
the Morphological Spatial Pattern Theory (MSPA) in order to recognize
core ecological sources. The Minimum Cumulative Resistance Model
(MCR) was used as the basis to construct a comprehensive resistance
surface by superimposing seven resistance factors, and ecological
corridors were divided into classes according to the gravity model.
Ecological pinch points and barrier points were identified as ecological
nodes by the Linkage Mapper tool based on the Circuit Theory. The
ecological network of source (surface)-corridor (line)-node (point) in
Yuncheng City was constructed. The results showed that: 1) There
were 9 core ecological source sites in Yuncheng City, 13 important
ecological corridors and 10 general ecological corridors were divided
by the gravity model and actual construction demand, and 17 key
ecological nodes and 34 general ecological nodes were identified.
2) The existing important ecological corridors are concentrated in the
south of Yuncheng, and the ecological connection in the north-south
direction is weak, so the construction of important ecological corridors
running through Jishan County, Xinjiang County and Wenxi County
can be prioritized to increase. 3) The comprehensive application of
MSPA model and circuit theory can enhance the scientificity and
accuracy of ecological network construction, which is conducive to
identifying key ecological restoration areas, providing strong support
for the layout of ecological restoration projects. |
