Embodiment Construction

[0044]The method and system for preventing natural disasters in small watersheds based on emergency plan visualization and rapid mapping proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention. In addition, the structures shown in the drawings are often a part of the actual structures. In particular, each drawing needs to display different emphases, and sometimes uses different scales.

[0045] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and description of the drawings of the present invention are intended to cover non-exclusive inclusion, for example, including a series of steps or units A process, me...

Abstract

The invention provides a method and a system for preventing natural disasters in a small watershed based on emergency plan visualization and rapid mapping. The method comprises the following steps: acquiring various information of the small watershed; carrying out rapid drawing to form a 3D simulation map; optimizing the 3D simulation map, and speculating the occurrence category and the occurrence possibility of the natural disaster so as to propose a preliminary emergency plan; and adjusting and optimizing the initial emergency plan to form a final emergency plan. A 3D simulation map is constructed and optimized through various types of information of the small watershed, so that the possibility, the occurrence area, the occurrence category and the occurrence time of the natural disasters in the small watershed area can be automatically calculated, and the prevention efficiency of the natural disasters in the small watershed area is improved; besides, the 3D simulation map can visually display the deduction process, so that people can visually and clearly observe the layout of the area where natural disasters possibly occur, the harm caused by the disasters and the like, and reference and auxiliary effects are achieved on prevention of the natural disasters. The problem of how to prevent small watershed natural disasters is solved.

Description

technical field [0001] The invention relates to the technical field of disaster prevention, in particular to a method and system for preventing natural disasters in small watersheds based on emergency plan visualization and rapid mapping. Background technique [0002] my country has a vast territory and complex terrain, so it has become one of the countries with the most serious geological disasters in the world. Among them, disasters such as landslides, landslides, mudslides, ground subsidence, ground fissures and ground subsidence seriously threaten the safety of people's lives and property, and restrict social economy. of sustainable development. [0003] A small watershed usually refers to a catchment area of ​​50 km below the secondary and tertiary tributaries, bounded by the watershed and the outlet section of the downstream channel. 2 The following relatively independent and closed natural catchment areas. Natural disasters in small watersheds mainly include soil e...
