以Arc GIS、Geoway等软件为数据平台,以SPOT5遥感影像为数据源,对安徽省休宁县岭南林场5幅1:10000地形图进行等高线地形数据和林地小班矢量化,建立数字高程模型(DEM)和优势树种(组)专题图层,进行地形分析及地形与优势树种(组)关联分析。结果表明,岭南林场海拔主要在300~800 m范围内,坡度主要是陡坡和急坡,坡向面积最大的是南坡。林场总体造林作业难度较大,生态脆弱性等级较高;森林资源主要集中在300~800 m的区域内,天然黄山松林、栎类林主要分布在800 m以上,硬阔天然林主要分布在800 m以下;松类和栎类主要分布在25°以上的坡度范围内,天然枫香林主要分布在陡坡和急坡;松类集中分布在阳坡和半阳坡,天然硬阔、栎类、枫香林主要分布在阴坡和半阴坡。
Using ArcGIS, Geoway and other software as data platform and SPOT5 remote sensing image as data source, five contour maps of 1: 10000 topographic maps in Lingnan Forest Farm, Xiuning County, Anhui Province, DEM) and dominant tree species (group) thematic layers, topographic analysis and topography and dominant tree species (group) association analysis. The results showed that the elevation of Lingnan Forest Farm was mainly in the range of 300 ~ 800 m, the steep slope and the steep slope were the major slopes, and the largest slope area was the southern slope. The overall afforestation operations of forest farms are more difficult and the level of ecological vulnerability is higher. The forest resources are mainly concentrated in the area of 300-800 m. The natural forests of Pinus taiwanensis and Quercus variabilis are mainly distributed above 800 m, while the hard and broad natural forests are mainly distributed within 800 m. The Pinus massoniana and Quercus mongolica were mainly distributed in the slope of more than 25 °. The natural sweet maple forest was mainly distributed on the steep slope and the steep slope. The pine forest was mainly distributed on the sunny and semi-sunny slopes, Xianglin mainly in the shady and semi-shady slope.
