Territorial ecological restoration (TER) is vital for China to address land degradation challenges, achieve its carbon neutrality strategy, and build the Beautiful China. However, the current TER planning system needs enhancement in its systematic, holistic, and integrated approach to support the unified conservation and restoration of mountains, rivers, forests, farmlands, lakes, and grasslands. This paper draws on the Land Degradation Neutrality (LDN) concept proposed by the United Nations Sustainable Development Goal 15.3 to establish a logical framework for LDN-oriented TER planning in China, highlighting key research questions to achieve LDN. The findings are: (1) The evolution of LDN reflects the global shift from fragmented to integrated ecological restoration projects. Its conceptual framework and implementation logic offer foundational and universal aspects that can guide the exploration of systematic TER planning in China. (2) LDN-oriented TER planning focuses on addressing land degradation through a singular metric (the proportion of degraded land) to achieve one goal (LDN), following a planning logic of "status analysis-degradation identification-setting LDN goals-identifying LDN pattern-implementing LDN measures-monitoring LDN". (3) Key research questions for achieving LDN in TER include diagnosis of ecological problems, identification of ecological restoration priority area, delineation of TER implementation units, and design of TER monitoring mechanisms. To promote the localization of the LDN concept, it is recommended to establish a balancing mechanism for ecosystem degradation and restoration, targeting the avoidance, alleviation, and restoration of quantity, quality, and productivity degradation across all land-use types, so as to coordinate planning formulation and project implementation.
