Integrating Top-Down and Bottom-Up Approaches Improves Practicality and Efficiency of Large-Scale Ecological Article

Zhaowei Ding, Hua Zheng, Jun Wang, Patrick O´Connor, Cong Li, Xiaodong Chen, Ruonan Li, Zhiyun Ouyang

Engineering 2023, Volume 31, Issue 12,   Pages 50-58 doi: 10.1016/j.eng.2022.08.008

Abstract: Top-down approach-based spatial planning, emphasizing hierarchical control within government structuresHere, we established a new ecological restoration planning approach linking a social–ecologicalThe new spatial planning approach integrates bottom-up approaches targeting stakeholder interests andThus, spatial optimization planning that integrates both top-down and bottom-up approaches can resultin more practical and effective ecological restoration than top-down approaches alone.
