Prevention and Defense Technologies for Natural Disasters: A Review
Main Article Content
Abstract
Based on the theoretical framework of natural disaster prevention and emergency response systems, this study analyzes the core connotations of "prevention" and "defense" within the pre-disaster prevention and control system for natural disasters, along with their synergistic mechanisms, uncovering their foundational roles in enhancing emergency response effectiveness and reducing disaster losses. The theoretical research results and practical models related to prevention and defense of natural disasters both domestically and internationally, are systematically reviewed in this paper, with a focus on analyzing the performance and existing issues in typical disaster cases, as well as analyzing successful cases and the shortcomings in actual emergency situations, by using literature review and case analysis. Through comparative case analysis, we propose three major research areas for future natural disaster prevention and defense: 1) advancing research on disaster mechanisms and innovating comprehensive prevention and control theories, 2) optimizing emergency management coordination systems and resilient resource allocation, and 3) strengthening technological support and enhancing social collaboration capabilities.
