| The landslide geological hazard frequently occur in the loess region in Northwest China. Middle segment of the West-East Gas Pipeline Project passes through the Loess Plateau,enduring landslide infringement.Taking a key locality of the West-East Gas Pipeline Project in loess region as study area,this paper focuses on the development and research of regional and monomer landslide forecasting and warning models and the landslide monitoring and warning system based on GIS,in order to study on how to establish a landslide geological hazard monitoring and warning system in the loess region with comparatively perfect functions.The core content of this paper is the designing and development of the landslide geological hazard monitoring and warning system in study area of the West-East Gas Pipeline Project.Relying on prolific geological surveying materials,the basic spatial data,geological hazard thematic data,pipe data and monitoring data of study area can be added to the landslide geological hazard monitoring and warning system with GIS. After that regional and monomer landslide forecasting and warning can be carried out combining with the study on warning models.The research of this paper includes the following content:â‘ The summary of the geological environment condition and loess landslide development characteristics in study area.â‘¡The research on regional landslide forecasting and warning models,including: the hazard zoning of landslide in study area,geology-meteorology coupling model,the critical value of rainfall, etc.â‘¢The research on monomer landslide forecasting and warningmodels,including: monomer landslide monitoring,cusp catastrophe model,the landslide warning Expert System,etc.â‘£The designing and development of the landslide geological hazard monitoring and warning system in study area of the West-East Gas Pipeline Project based on GIS,including:system overall design,database construction,system functionrealization, etc.
