Abstract

The invention provides a village and town geological disaster risk estimation method and system, and the method comprises: collecting village and town geological disaster historical cases, and building a village and town geological disaster case library with a spatial relation based on a GIS analysis and management technology; clustering cases in the village and town geological disaster case library through an AUTOCLUST algorithm, and preliminarily dividing the village and town geological disaster case library; performing core feature extraction and feature weight distribution on cases in therural geological disaster case library through a rough set and a genetic algorithm; and retrieving a target case in the village and town geological disaster case library based on the case attribute features and the space elements to obtain a historical case most similar to the target case for case reuse. According to the scheme, the problem that the existing disaster risk estimation accuracy is not high is solved, and the rural disaster risk estimation precision and the case-based reasoning time efficiency can be improved.

Description

technical field [0001] The invention relates to the field of disaster prevention and control, in particular to a method and system for estimating the risk of geological disasters in villages and towns. Background technique [0002] Frequent geological disasters cause huge damage to people's lives, properties and the environment. As one of the countries with a relatively high proportion of natural disasters, 60% of geological disasters occur in villages and towns. Compared with cities, geological disasters in villages and towns are affected by geographical location and climatic conditions. Influenced by infrastructure, economic foundation, etc., disasters are characterized by wide distribution, various types, and frequent occurrence. Geological disasters occur in a complex environment, coupled with incomplete or missing data, which makes it difficult to assess disaster risks and effectively prevent them. . [0003] With the help of Case-Based Reasoning (CBR), this kind of vi...
