摘要
森林资源空间数据是开展林业基础科学研究的主要空间信息,丰富的、多源的、多时间尺度的空间数据能够全面展现森林资源和生态的变化状况,也是开展空间分析的基础。不同调查手段获取的森林资源空间数据包含不同的空间特质,以不同来源的森林资源空间数据为例,分析其内在特质及差异性表现形式,揭示森林中包含的各种因素之间的空间交互关系和内在变化规律。同时,本文通过森林资源空间数据的关联性分析,实现多源性森林资源空间数据的统一表达,为林业资源空间语义检索与共享服务提供空间信息支撑。
Spatial data of forest resources is the main spatial information of data integration of forest management.The spatial data from various categories,resources,and time-scales can provide a comprehensive picture of the changes in forest resources and the ecological environment,which is also the basis of spatial analysis.Through the analysis of its internal characteristics and its different manifestations,this paper reveals the relationship and internal change laws among the various factors contained in the forest.Meanwhile,through the analysis of the correlation of forest resource spatial data,the unified expression of spatial data on multi-source forest resources is realized.And multi-source spatial data provides spatial information support for forest resource information management and shared services.
