Landslide is more universal calamity in mountain areas. It is a threat to life and socio-economy. The ghat section Calicut–Nilampur–Gudalur State Highway 37 (SH-37) comes under the Survey of India toposheet 58A/7. It is important road network to connect Calicut. The study area is covered in 6.5 km ghat section of 103/6 to 109/8 km stone on SH 37. This study was carried out to prepare landslide susceptibility zonation (LSZ) mapping on 1:50,000 scale using frequency ratio model. Seventeen parameters such as elevation, slope, slope aspect, curvature, road buffer, drainage buffer, lineament buffer, land use, geomorphology, run-off, drainage density, drainage frequency, lineament density, lineament frequency, weathering condition, soil thickness and geology were considered as landslide-inducing factors. LSZ map was organized by manipulating association between the landslide persuade factors and old landslide using this model. Study area has grouped into five levels of susceptibility groups such as very low, low, moderate, high and very high. The LSZ map was validated by the old landslide record data collected from field. The landslide inventory percentage fall in very low hazard is 1.02%, 1.03% under low-susceptibility, 7.22% in moderate-susceptibility, 39.18% present in high-susceptibility and 51.55% noticed in very high-susceptibility zone, and using these data, the 18 rock vulnerable cut slopes were identified.

使用双变量统计频率比方法和 GIS 绘制滑坡敏感性分区图：SH 37 Ghat Road, Nadugani, Panthalur Taluk, The Nilgiris 部分案例研究

山体滑坡是山区较为普遍的灾害。它对生命和社会经济构成威胁。Calicut-Nilampur-Gudalur 37 号国道 (SH-37) 的河坛路段属于印度调查地形表 58A/7。是连接卡利卡特的重要公路网。研究区覆盖在 SH 37 上 103/6 至 109/8 公里石头的 6.5 公里加特段。本研究是为了使用频率比模型在 1:50,000 比例尺上准备滑坡敏感性带 (LSZ) 绘图。高程、坡度、坡向、曲率、道路缓冲、排水缓冲、线性缓冲、土地利用、地貌、径流、排水密度、排水频率、线性密度、线性频率、风化条件、土壤厚度和地质等十七个参数被认为是滑坡诱发因素。LSZ 地图是通过使用该模型操纵滑坡说服因素与旧滑坡之间的关联来组织的。研究区已分为五个级别的易感性组，如极低、低、中、高和极高。LSZ 地图通过从现场收集的旧滑坡记录数据进行验证。极低危险区滑坡库存百分比下降为1.02%，低易发区为1.03%，中易区为7.22%，高易区为39.18%，特高易区为51.55%，使用这些数据，确定了 18 个岩石脆弱的切割斜坡。LSZ 地图通过从现场收集的旧滑坡记录数据进行验证。极低危险区滑坡库存百分比下降1.02%，低易发区1.03%，中易发区7.22%，高易发区39.18%，极高易发区51.55%，利用这些数据，确定了 18 个岩石脆弱的切割斜坡。LSZ 地图通过从现场收集的旧滑坡记录数据进行验证。极低危险区滑坡库存百分比下降为1.02%，低易发区为1.03%，中易区为7.22%，高易区为39.18%，特高易区为51.55%，使用这些数据，确定了 18 个岩石脆弱的切割斜坡。
