## 1 Introduction  
China boasts a large landmass, a variety of topography and landforms, intricate geological structures [1], and delicate geological environments [2]. In addition, with the continuous development of modern science and technology and socio-economic development, human exploitation of resources and natural pioneering activities have led to a decrease in the stability of the earth's surface, which has created conditions for the breeding of disasters. Extreme weather occurrences and increased human engineering operations have led to a significant increase in geological disasters in recent years [3]. China is now among the nations in the world where geological disasters are widely distributed and have a significant impact [1, 4]. As a result, incidents of major economic losses have occurred from time to time, and the situation of geological disaster prevention and control remains critical. In 2022, China's natural disasters were dominated by floods, droughts, wind and hail, earthquakes and geological disasters. According to the summary of geological disasters in China in 2021, a total of 4772 geological disasters occurred nationwide, resulting in 80 deaths, 11 missing, and direct economic losses of CNY 3.2 billion. In the distribution of geological disasters released in China in 2021, there were 2335 landslides, 1746 avalanches, 374 mudslides, 285 ground collapses, 21 ground fissures, and 11 ground subsidence. In terms of disaster level, there were 35 extra-large geological disasters, 27 large geological disasters, 328 medium geological disasters, and 4382 small geological disasters [5]. The distribution of geological disasters in 2021 shows that landslide disasters are the main ones, followed by avalanche disasters, reflecting that among the various types of geological disasters, China's geological disasters are dominated by landslide disasters, which are of various types and have great dangers, and urgently need to be evaluated by scientific and reasonable methods of risk assessment. The disaster situation reflects that China's geological disasters are still mainly small- and medium-sized, which is basically consistent with the situation worldwide. Landslides are a major geohazard, and economic losses due to geo-environmental degradation and geohazards in developing countries amount to more than 5 percent of the gross national product annually [6]. In China, among the environmental problems caused by disasters, losses due to geological disasters account for about 35 percent of the overall disaster losses, and about 55 percent of these losses are caused by avalanches, landslides, mudslides and human-engineering-induced shallow-surface geological hazards, which cause enormous difficulties in post-disaster reconstruction work. Landslides are common geological hazards that take a heavy toll on human life and infrastructure every year, making it crucial to identify potential landslides [7]. The Yili Valley, with its varied topography and delicate and intricate geological environment, is situated in Xinjiang's western region of the Tianshan Mountains. The area frequently experiences geological disasters like mudslides, landslides, and collapses, which pose a major threat to the protection of locals' lives, property, and the ecological environment [8; 9]. Geological hazard susceptibility assessment is imminent. In recent years, geological disaster risk assessment has become a research hotspot for many scholars (e.g., Academician [PERSON], Academician [PERSON], and Professor [PERSON] in China), and fruitful research results have been obtained. However, from the current study, it seems that the complexity of the content of the geological hazard evaluation makes it important to study in depth how to transfer the qualitative evaluation to quantitative evaluation. Meanwhile, with the continuous development of computers and related technologies, how to better simulate the conditions of geohazard development and integrate various technologies for geohazard risk assessment is the current difficulty [10].
