Preliminary Study on Disaster Prevention Planning System from the Perspective of High-Density Urban Environment

High-density development mode is a realistic and rational choice of urban space in the process of high-speed urbanization in China. However, as the disaster-bearing body of urban disasters, the high-density characteristics of urban space also make it vulnerable and sensitive in dealing with disasters. Therefore, how to strengthen the protection of urban disaster prevention facilities and continuously improve the adaptability and flexibility of the city is an important factor to promote the sustainable development of high-density cities, which has great research value. Based on this, this paper aims to study and summarize the disaster characteristics of the high-density global metropolis, and preliminarily explore the content of disaster prevention planning system in high-density urban environment, so as to provide a pertinent research basis for the relevant issues of high-density urban disaster prevention.
