Selecting optimal revegetation patterns and filtering priority areas can improve the effec-
tiveness and efficiency of revegetation planning, particularly in areas with severe vegetation damage.
However, few people include optimal revegetation patterns and priority restoration areas into reveg-
etation plans. The Near-Nature restoration pays attention to “based on nature” ideas, guiding the
degraded ecosystems to reorganize and achieving sustainable restoration through self-regulation.
In this study, we conducted a field survey of the native vegetation communities in the Yanhe River
catchment, and the data obtained were used to construct the potential distribution suitability of the
habitat and screen the priority areas through the combination of MaxEnt and prioritizr models. We
drew a heat map of species richness by simulating the potential distribution of 60 native species.
The results showed that the potentially suitable habitats for forest cover were distributed in the
southern part of the Yanhe River catchment; the potentially suitable habitats for herbaceous plant
species were located in the center and the northwest parts of the study area; the potentially suitable
habitats for shrub plant species in this area were larger than that of the forest, and herbaceous plants
species were distributed in many zones of the study area. This study demonstrated that shrubs and
herbaceous plant species in parts of the Loess Plateau should be considered as the pioneer plants
of revegetation in future revegetation plans. Moreover, we also mapped the priority area of the
Near-Nature restoration based on the richness of the potential native species. The procedure followed
in this study could provide guidance for revegetation planning and manual management in the
regions where vegetation damage occurs.
