基于RS与GIS地震灾害后森林植被重建的关键技术探讨
|
摘要
简要分析地震灾害对森林植被造成的破坏,指出森林植被灾后重建的必要性和重要性。探讨分析RS与GIS技术在地震灾害后森林植被重建中林区道路选址与区划、森林植被受害状况统计、生产恢复条件调查、林地适宜性评价与树种选择、森林植被空间优化配置及恢复评价等方面的重要作用,以期为灾后森林植被的重建工作提供理论参考与技术支持。
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.
