摘要:
以安徽省休宁县2009年SPOT5遥感影像为数据源,以ArcGIS10.0为数据加工与分析平台,建立不同林地类型遥感影像解析标志,进行林地小班界矢量化数据采集,生成Shp.格式小班图形数据,与小班属性数据链接,形成休宁县林地小班图形与属性数据库,并对林地结构、林地保护等级、林地功能分区及林地保护利用方向进行了分析。结果表明,休宁县林地面积177028.44 hm2,其中,有林地154457.32 hm2,疏林地1062.07 hm2,灌木林地14116.48 hm2,未成林地5759.55 hm2,苗圃地33.39 hm2,无立木林地587.09 hm2,宜林地1012.23 hm2,其他林业辅助生产用地0.31 hm2,以有林地和灌木林地居多,共占林地面积的95.2%;林地保护等级共有4级,各等级林地面积由大到小依次是Ⅱ级>Ⅲ级>Ⅰ级>Ⅳ级;全县林地分为4个主体功能区,包括北部风景林与水源涵养林发展区,中部休闲风景林与经济林发展区,西南部商品林发展区和东南部商品林与公益林发展区。本研究为制定休宁县林地一张图、实现林地资源数字化管理奠定了基础。

Abstract:
Based on the SPOT5 remotely sensed imagery of Xiuning county of Anhui Province acquired in 2009 c and ArcGIS10.0, the image interpretation marks were established to collect data of sub-compartments’ boundaries and attributes. Furthermore, the forest-land structure and protection status were assessed, followed by the analyses of their functional zonation, protection and utilization orientations. The results showed that the forestland area of Xiuning was 177028.44 hm2, including 154457.32 hm2 of closed forest land, 1062.07 hm2 of sparse forest land, 14116.48 hm2 of shrub forestland, 5759.55 hm2 of immature forestland, 33.39 hm2 of nursery, 587.09 hm2 of no stumpage forestland, 1012.23 hm2 of land suitable for afforestation, and 0.31 hm2 of other land for forestry production. The majority of the forestland was closed forest land and shrub forestland, accounting for 95.2% of the total forestland area. Forest protection level was divided into four levels. The forestland area of different protection level was Ⅱ>Ⅲ>Ⅰ>Ⅳ. Forest land was divided into four main functional areas in Xiuning County, including the scenic forest and water conservation forest development zone in the north, the scenic forest and economic forest development zone in the middle, the commercial forest development zone in southwest and commercial and public welfare forest development zone in southeast Xiuning. The results would provide a foundation for assembling all types of forests in Xiuning County into one map and facilitate the computerized management of forestland resources.
Key words:  RS  GIS  definition of forestland border  forestland protection level  forestland functional partition
