| 摘 要： | 以海南尖峰岭林区森林景观为研究对象，利用DEM和2013年森林资源清查数据，分别对林区森林景观二维和三维的景观特征和景观适宜粒度进行分析。结果如下：混交林是林区优势森林景观，分布较广，乔木林地斑块数量最多，竹林地和苗圃地是劣势森林景观，苗圃地比竹林地分布集中；数据格式转换对森林景观面积和斑块数量有影响，混交林地和乔木林地变化最大；竹林地、苗圃地和无立木林地斑块数量没有发生变化，但竹林地和苗圃地的面积却减少，无立木林地面积增大；灌木林地主要分布在海拔300~500m，混交林地主要分布在海拔500~700m，乔木林地主要分布在海拔300~500m，苗圃地全部分布在海拔0~300m，无立木林地主要集中分布在海拔300~500m，宜林地在海拔0~300m分布最多，竹林地在海拔300~500m分布最多；地形对尖峰岭林区景观适宜粒度几乎无影响，尖峰岭林区适宜景观分析粒度为海拔150m。该结果为科学经营管理尖峰岭林区森林资源提供参考依据。

| Abstract: | The paper studied the forest landscape in Jianfengling forest with the DEM and 2013 forest resources inventory data. Researching on II and Ⅲ dimensional landscape features of forest landscape and suitable particle size of landscape. Draw the following conclusions: mixed forest was the dominant forest landscape, distribution widely, the number of patch in high forest was the largest, bamboo and nursery were the inferior forest landscape, distribution of nursery were more concentrated than bamboo; data format conversion effect on landscape area and patch number, the mixed forest and high forest changed obviously, the patch number of bamboo, nursery and no standing woodland has no changes, but the area of bamboo and nursery was reduced, no standing woodland area increased. shrubs woodland mainly distributed at the altitude of 300-500m, the mixed woodland distributed at the altitude of 500-700m, trees woodland mainly distributed at the altitude of 300-500m, all of nurseries distributed at the altitude of 0-300m, no standing woodland mainly concentrated distributed at the altitude of 300-500m, suitable forest land mainly distributed at the altitude of 0-300m, at the altitude of 300-500m, the bamboo area was the largest. Terrain almost has no influence on suitable particle size of landscape in Jianfengling forest. The suitable particle size of landscape was 150m in Jianfengling forest. The conclusions provided guidance and reference for the scientific management of Jianfengling forest resources. |
