Optimization of Forest Road Network Based on Accessibility of Fire Water Reservoirs

Abstract: This study focuses on the application of water-based firefighting techniques in forest fire prevention, particularly the crucial impact of the accessibility of forest fire prevention facilities, such as water reservoirs, on firefighting efficiency. Given the safety, efficiency, and cost-effectiveness of water-based firefighting techniques, there is ongoing research and development of these technologies globally. As a core firefighting infrastructure, the layout and accessibility of forest fire prevention reservoirs directly influence the efficiency and effectiveness of forest fire suppression, playing a vital role in minimizing fire damage.
This paper delves into the issue of accessibility to forest fire prevention reservoirs and uses it as an entry point to conduct a systematic optimization study of the road network within forest areas. During the research process, we developed an optimization model for the forest road network that comprehensively considers multiple factors, aiming to enhance the rapid response and water retrieval capabilities of the reservoirs in emergency situations. This model not only takes into account practical constraints such as road construction costs and topographical conditions but also fully integrates ecological protection requirements to ensure that the optimization solution aligns with sustainable development principles while improving efficiency. By employing heuristic algorithms, we derived optimal or near-optimal road layout solutions.
In the empirical research section, we selected a representative forest area as the research object and applied the constructed optimization model to its road network planning. Through a comparative analysis of the accessibility indicators of the reservoirs before and after optimization, we found that the optimized forest road network significantly improved reservoir accessibility, effectively reducing rescue time and notably enhancing the forest area's fire prevention capabilities.
This study not only provides a scientific theoretical basis and practical guidance for the optimization of forest road networks but also holds significant practical implications for enhancing forest fire prevention levels worldwide. Looking ahead, with the continuous advancement of water-based firefighting techniques and the ongoing improvement of forest road networks, we have reason to believe that the accessibility of forest fire prevention reservoirs will further increase, making even more positive contributions to protecting valuable forest resources and maintaining ecological security.
