Technical approaches to addressing ecological red-line management challenges in ecological security

As rapid industrialization, urbanization, and globalization heighten the urgency for ecological security worldwide, China faces a critical challenge in balancing economic development with environmental preservation. In response, China has implemented various ecological initiatives, with the establishment of ecological red lines as a cornerstone of its environmental governance and a fundamental strategy to safeguard ecological security. This study provides a comprehensive examination of the evolution of ecological protection red lines and the recent release of the Technical Guidelines for the Delineation of Ecological Protection Red Lines to develop a technical plan for regional ecological protection red-line management and control. It focuses on ecological security concerns, and the key considerations encompass defining essential concepts, highlighting the adverse impacts of human activities to justify the adoption of restrictive systems, recognizing regional disparities in resources, environment, and socioeconomic context, and employing multi-scale research methodologies for comprehensive data acquisition. The study addresses diagnosing ecological security issues, establishing prevention objectives and management goals, categorizing types of regional ecological protection red-line management and control, delineating spatial boundaries, and incorporating historical insights to propose scientifically grounded response strategies. These strategies aim to address ecological security challenges threatening ecological protection red lines while integrating extensive social feedback to ensure practicality and effectiveness.
