Study on Methods of Urgent Refuge Planning based on GIS

摘要

Damage of disaster to residents can be mitigated by urgent refuge. But the old way to plan urgent refuge is not reasonable. So techniques and methods are needed. Geographic Information System(short for GIS) as a new technique and method is of some import to planning urgent refuge. Calculating the impact of factors in each raster, distribution maps of Euclidean distance is got. Then, the maps of factor which get different weight index are calculated by overlay way. The last map is as planning urgent refuge. After that, the way is used in a country as a test application. The result shows that the way based on GIS makes planning urgent refuge more scientific and more reasonable. Planning the country urgent refuge proposed is worthy to use for reference.
