Abstract: A method and system for determining coastal erosion disaster early warning lines and calculating spatial scope thereof. The method includes determining a coastal erosion rate according to coastal erosion change monitoring data and landform data; and calculating at least one coastal erosion early warning line in coming N years in conventional conditions according to an established coastal erosion rate calculation method; determining the at least one coastal erosion early warning line in N years in extreme conditions by increasing influencing factors of accelerated sea level rise and extreme storm waves and utilizing a determination and calculation method of coastal erosion disaster early warning lines; and obtaining a coastal erosion retreat position and scope and sending early warning based on the coastal erosion rate in conventional conditions and the at least one coastal erosion early warning line in extreme conditions.
