Landslide susceptibility in the Greater Bogor Area is a significant concern due to its hilly topography, soil types, and high rainfall. This research examines the geographical and temporal variations in landslide susceptibility and the relationship between land use change, rainfall, and landslide occurrence. Landsat 7 ETM+, CHIRPS, and DEM satellite data were used to simulate landslide susceptibility. The study used 2000, 2010, and 2020 data to examine land use and precipitation changes. The weighted overlay method created a landslide susceptibility model that considered precipitation, land use, slope, rock, and slope. The association between land use change, rainfall, and landslide susceptibility was examined using correlation analysis. According to the findings, the Greater Bogor Area is highly prone to landslides, with a growing tendency in landslide events. 22.48% of the area has a very high susceptibility classification to landslide; meanwhile, 66.46% has a high susceptibility classification. Moreover, this study also found that the land use factor correlates more positively with landslide susceptibility than the rainfall factor. Overall, this study underlines the need to take land use dynamics and rainfall patterns when assessing landslide susceptibility and the need for effective mitigation measures in the area.

大茂物地区滑坡敏感性多时相分析及其与土地利用变化和降雨变化的关系

由于丘陵地形、土壤类型和高降雨量，大茂物地区的山体滑坡敏感性受到严重关注。本研究探讨了滑坡敏感性的地理和时间变化以及土地利用变化、降雨和滑坡发生之间的关系。 Landsat 7 ETM+、CHIRPS 和 DEM 卫星数据用于模拟滑坡敏感性。该研究使用 2000 年、2010 年和 2020 年的数据来研究土地利用和降水变化。加权叠加法创建了考虑降水、土地利用、坡度、岩石和坡度的滑坡敏感性模型。使用相关分析检查土地利用变化、降雨和滑坡敏感性之间的关联。研究结果显示，大茂物地区是山体滑坡的高发区，且山体滑坡事件有增加的趋势。 22.48%的地区具有极高的滑坡易发性等级；同时，66.46%的人具有高易感性分类。此外，本研究还发现，土地利用因子与滑坡敏感性的相关性比降雨因子更显着。总体而言，本研究强调在评估滑坡敏感性时需要考虑土地利用动态和降雨模式，以及在该地区采取有效缓解措施的必要性。
