【摘要】 以吉林省汪清林业局金沟岭实验林场为研究对象,在ArcGIS平台下,根据社会需求和研究区森林调查数据,采用层次分析法构建基于GIS的森林多功能评价指标体系。利用GIS的空间分析功能评价母树保护、木材生产、水土保持和护路4个主要森林功能并制作森林功能区划图。结果表明:评价结果符合林场经营目标,也符合用材林、母树林成面,护路林成线和水土保持林点状分布的特点。更多还原

【Abstract】 According to the social requirements and forest resources survey data,by taking the Jingouling Forest Farm of Wangqing Forestry Bureau in Jilin Province as an example,the forest multi-function evaluation system was established with ArcGIS platform and using Analytic Hierarchy Process.The impact extent of different evaluation factors on sub-lots with the application of ArcGIS spatial was analyzed.The multi-functions of the Nature Reserve,etc.seed tree protection,wood production,road maintenance,soil and water conservation were evaluated and the forest farm’s forest function regionalization map was drawn.The results show that the evaluation results are consistent with the forest management goals,while also meet the distribution features that Nature Reserve forest,timber forest and seed tree production forest are in planar shape,soil and water conservation forest is in point shape and road protective forest is in linear shape.更多还原
