| Rural Ecological Restoration Strategies in PlainAgricultural Areas Based on the Identification ofEcological Characteristics and Issues throughClustering—A Case Study of Heishan County,Liaoning Province |

| Abstract: |
| Long-term cultivation activities in plain agricultural areas
have caused a continuous and extensive impact on ecosystems,
which resulted in the shrinkage of woodlands, wetlands, and
other ecological patches and interrupted natural processes. Rural
ecological restoration is one way to enhance the sustainability
of the agricultural production system. As agricultural production
is highly dependent on natural processes, in situ ecological
characterization and analysis are prerequisites for proposing
appropriate ecological restoration strategies. This study is rooted in
regional natural processes and in situ ecological problem analysis.
Based on organizing the interaction logic of ecological processes
and problems in the plain agricultural area, this paper proposes a
practical framework for ecological restoration and takes Heishan
County, a typical plain agricultural city, Liaoning Province, as an
example for study. Based on the understanding of the ecological
situation in Heishan County, this area was divided into 3,969
samples with similar characteristics based on multi-resolution
division and then clustered into eight groups by the K-Medoids
method. Further, the study area was categorized into six ecological
restoration zones, and in situ restoration strategies were proposed
to restore the dominant natural processes and micro-circulations of
the regions, enhancing the ecological resilience of plain agricultural
and rural areas. |
