Abstract:

The intensification of climate change and human activities has led to a severe situation of frequent wildfires globally, posing a significant threat to forest ecosystems. Constructing effective firebreaks and firebreak systems is crucial for preventing and mitigating the spread of wildfires. This paper first outlines the mechanisms of biological firebreaks, including species selection, structural design, and fire environment regulation, and explores key factors such as site selection, width design, species configuration, and spatial layout for firebreaks. Secondly, the study reviews the types, functions, and methods of fuel removal for engineering firebreaks, with a focus on the planning and design of forest roads. Third, the study examines the key factors influencing the effectiveness of firebreaks and evaluates their practical efficacy, and further analyzing the applicability and limitations of different assessment methods. Finally, the study looks forward to future research directions in five specific areas: the multi-layered composite design of biological firebreaks; diversified planning and layout of engineering firebreaks; green, efficient, and low-cost fuel management technologies for firebreaks; assessment techniques for the fire-retardant effectiveness of biological firebreaks; methods for determining the optimal width and density threshold for firebreaks.

Key words: firebreak, firebreak system, biological firebreak, engineering firebreak; fuel management; firebreak effectiveness assessment
