Discussion on the key techniques for post-disaster forest vegetation's reconstruction based on RS and GIS.

The thesis gives a brief analysis on forest vegetation damages caused by earthquake,points out the necessity and signifiance of the forest vegetation's reconstruction,and analyses the use of the technologies of remote sensing and geographic information system.They could be drawn on in many aspects of the reconstruction,such as the site selection and division of forest roads,statistics of damaged situation of forests,investigation of the recovering conditions of production,forest land suitability assessment and choice of tree species,optimal allocation of forest vegetation and the evaluation of the resumption,so as to provide a theoretical reference and technical support for the post-disaster forest vegetation's reconstruction.
