Identifying key areas and implementing land consolidation and ecological restoration projects
is an effective approach to improving regional ecological security. Effects assessment of pre-set projects
can promote land consolidation and ecological restoration more pertinently. Taking Daguan County,
Yunan Province, as the study area, the key areas of land consolidation and ecological restoration
were identified by Circuit theory. Land consolidation and ecological restoration projects were
pre-set according to the terrain’s suitability. Then, the ecological effects of the projects on the ecosystem
were evaluated. The results showed that (1) a total of 12 ecological barrier points with an area
of 37.16 km2 were identified as the key areas for land consolidation and ecological restoration.
(2) Ecosystem services such as water and soil conservation, carbon storage, and habitat quality can
be improved by implementing land consolidation and ecological restoration projects, respectively.
(3) Projects in the middle of Daguan County that can improve comprehensive ecological effects should
be prioritized, as more ecosystem service functions can be provided. It provides the decision-making
reference for land consolidation and ecological restoration management.
