摘要：The present study area, the Lish River basin of eastern Darjiling Himalaya shows extensive tea cultivation, deforestation, expansion of communication and settlement, shifting cultivation, unscientific and unplanned land use practices. All these activities have brought a tremendous threat to the population living in the Lish river basin causing devastating landslip. Although, various attempts were being taken to combat and check the landslide phenomena but a systematic and quantitative assessment and prediction of landslides are to be made in detail for planning and development. The assessment and prediction of the landslide phenomena are the prime concern of landslide mitigation. The present study is dealt with the assessment and prediction of landslide prone area in the Lish River basin. To make the landslide susceptibility map of the Lish river basin, some landslide inducing factors i.e. slope angle, slope aspect, slope curvature, drainage, lithology, geomorphology, soil, land use and land cover, and NDVI were taken into account and all the data layers were developed using RS and GIS tools. To integrate all the data layers Overlay analysis method on GIS platform were performed and landslide susceptibility map of the Lish river basin were prepared.
