目前,随着生存的环境恶化日益严重,环境问题严重制约社会经济的发展以及居民的生活质量。而急剧增长的人口数量也在消耗大量的自然资源,致使地质灾害频繁发生。因此,对地质灾害易发区有效划分、提前做好地质灾害评价,对预防地质灾害的发生起到一定预防作用。基于此,文章以北京市为例,结合GIS技术构建地质灾害易发程度分区评价模型,通过定量模型定量分区地质灾害易发程度,给地质灾害调查与分区地质灾害易发程度提供新的理论参考。
At present, with the deterioration of the living environment worsening, the environmental problems severely restrict the development of the society and economy and the quality of life of the residents. The rapidly growing population is also consuming a large amount of natural resources, causing frequent geological disasters. Therefore, the effective division of the prone areas for geological disasters, geological disasters in advance to do a good job, to prevent the occurrence of geological disasters play a preventive role. Based on this, the article takes Beijing as an example, constructs the evaluation model of geohazard prone degree with the GIS technology, and quantitatively models the susceptibility degree of the geohazard by the quantitative model, provides a new theoretical reference for the investigation of geological disasters and the susceptibility to regional geological disasters. .
