Abstract: Taking a large open pit slope as background，the research approach of displacement monitoring data analysis based on GIS is put forward according to the monitoring data of the slope displacement，and GIS basic database including attribute data and graphic data is set up.Relying on ArcGIS operation platform，the GIS visualization research and analysis of slope displacement in the open pit mine monitoring data is realized.The results show that the lower region of the slope is at a good stability state，and some regions in west slope and the top region in northeast slope are at bad stability state with larger displacement.At the same time，the application of GIS technology to analyzing slope displacement monitoring data can express slope stability situation in a more intuitive and accurate way，and the working efficiency and informatization level can be improved.

Key words: Slope, Displacement, Monitoring data, GIS visualization
