摘  要：
以GEOWAY软件为矢量数据采集平台,以自动矢量化1∶1万地形图的方式采集等高线、高程值、森林小班作为基础数据,然后以SHP文件格式导入到ArcGIS中生成数字高程模型,利用ArcGIS强大的地形分析功能,对紫蓬山的地形从坡度和坡向2个方面进行了分析,并分析地形与森林资源空间分布的关系.结果表明,紫蓬山地形起伏不大,属于丘陵岗地,造林树种集中在平坡和缓坡,森林资源多分布在平坦和北方向地区.

摘  要：
Taking GEOWAY software as the vector data acquisition platform,according to the way of vectoring automatically 1∶10,000 topographic diagrams to collect contour line,elevation value and subcompartment as the basic data,then importing SHP file into ArcGIS to generate the digital elevation model,the topography of Zipeng mountain was analyzed considering both slope and aspect,and the relationship between topography and the spatial distribution of forest resources was studied.The study results showed that the terrain undulating was not great in Zipeng mountain,the tree species was centralizedly distributed in flat and gentle slope,and most of the forest resources were distributed in flat land in north part of the mountain.
