Problems solved by technology

People’s expression of risk maps mostly stays in the assessment of the risk itself, and the comprehensive and general analysis of the content of the risk map is relatively weak due to changes in the scale or map use in a specific area

Abstract

The method belongs to the technical field of comprehensive control of natural disaster risk maps, and discloses a comprehensive control system and method for a point-shaped natural disaster risk map under a layer constraint. An LC-FIS model is applied to carry out initial exploration on the point-shaped natural disaster risk map automatically and comprehensively, and multi-scale automatic and comprehensive expression application is carried out. An automatic and comprehensive model for the point-shaped natural disaster risk map of a layer constraint-fuzzy inference system (LC-FIS) is preliminarily constructed based on geographical, cartographic and disaster theories. According to the system and the method, a regional differentiation rule can be well embodied on the expression of the Chineselandslide disaster, and constraint layers such as hazard inducing environments, disaster-inducing factors, disaster situations and the like are selected, so that the space distribution of high-risk regions is revealed, and a new method and a new idea are provided for multi-scale regional disaster risk management and decision making.

Description

Technical field [0001] The invention belongs to the technical field of comprehensive control of natural disaster risk maps, and in particular relates to a point-shaped natural disaster risk map comprehensive control system and method under layer constraints. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: [0003] As an important non-engineering measure, natural disaster risk map can play an important role in the loss assessment of disaster-prone areas and auxiliary decision-making for disaster prevention and relief. It not only has very significant socio-economic disaster reduction benefits, but also Provide strong scientific decision-making basis in other fields. The application of automatic synthesis in disaster risk maps is particularly urgent. At present, there are still very few comprehensive analysis of mapping for disaster risk maps at home and abroad. People’s expressions of risk maps mostly remain in the ass...
