The Forest Resource Geo-science Analysis and Application in Forest Fire Risk Based on RS and GIS

摘要

With the development and application of Computer Technology and RS and GIS, the data and method related with geo-science have enriched data sources and research methods of geo-science analysis. This article was from the forest space differentiation model and 3-d display of study area to carry on the forest geo-science analysis by the RS and GIS technology, and applied it into the study of forest fire disaster risk regionalization for building an assessment model of forest fire disaster risk indexes. It got a level image of forest fire risk regionalization of LinXi county by using AHP and the Weighted Superposition method of GIS. It can provide a basis for making decision for forestry management.
