Study on disaster prevention system in key areas of urban forest park with multi-factor coupling-- Chengdu Longquan Mountain as an example

Urban forest parks are major ecological sites in the suburban areas of large cities with good forest vegetation and forest ecological environment, providing people with recreation, tourism, fitness and other suburban activities, and are an important component of the urban landscape system. The spatial density and development intensity of people, facilities and places in the park are higher than those in general forest areas, and the risk of forest disasters is high. To effectively prevent the occurrence of forest disasters and ensure the safety of touring, this paper takes Chengdu Longquan Mountain Forest Park as an example, and divides the key areas of the forest park into high risk areas, medium risk areas and low risk areas through coupled analysis of forest fire risk factors, forest pest risk factors and geological disaster risk factors, and builds a system of prevention, prevention, resistance and rescue for different risk levels. The system is a combination of prevention, resistance and rescue, with points leading to lines, and lines leading to surfaces, forming a disaster prevention system that combines “points, lines and surfaces”, with human, physical, technical and institutional prevention complementing each other, providing a model for reducing the risk of disasters and ensuring the health and safety of forest parks.
