With the development of economy, a large number of human development activities in the natural environment have directly or indirectly increased the possibility of geological disasters. Every year a large number of geological disasters pose a serious threat to the safety of human life and property, and the effective management of geological disasters has become one of the major difficulties facing our country. This paper mainly studies the risk assessment of geological hazards of the line landslide based on remote sensing and GIS. Combined with detailed survey items of geological disasters in a certain area, this paper evaluates and analyzes the distribution and development characteristics of landslide geological disasters in the study area. Disaster assessment is an important part of disaster prevention and mitigation, and provides important references for local infrastructure construction, tourism development, urban planning and regional economic development. It can be known from the experiments in this paper that the evaluation results based on the hierarchical entropy variable weight method are more accurate, and the accuracy rate is 67%. The hierarchical entropy variable weight method can not only synthesize the rich experience of experts, but also reduce the subjective impact by introducing an entropy algorithm, thereby obtaining more accurate evaluation results.

随着经济的发展，自然环境中大量的人类发展活动直接或间接地增加了地质灾害的可能性。每年都有大量的地质灾害对人类生命财产安全构成严重威胁，有效管理地质灾害已成为我国面临的主要困难之一。本文主要研究了基于遥感和GIS的线状滑坡地质灾害风险评估。结合某地区地质灾害的详细调查项目，对研究区滑坡地质灾害的分布和发展特征进行了评价和分析。灾难评估是防灾减灾的重要组成部分，并为当地基础设施建设，旅游业发展，城市规划和区域经济发展提供重要参考。从本文的实验可以看出，基于层次熵变权法的评估结果更为准确，准确率为67％。层次熵变权重法不仅可以综合专家的丰富经验，而且可以通过引入熵算法来减少主观影响，从而获得更准确的评估结果。
