摘要
基于格氏栲自然保护区林业基本图(1∶10 000),在地理信息系统软件arcview和景观结构分析软件fragstats支持下,从景观总体特征、斑块面积、斑块周长、斑块数等角度对景观格局和破碎化程度进行分析和评价。结果表明,其它硬阔林、马尾松林和格氏栲保存的较为完整,旱地的破碎化程度最高;从总体来说,格氏栲自然保护区景观破碎化程度较小,景观具有较好的完整性。
Based on the forestry basic map of Castanopsis kawakamii Hayata nature reserve, using the geography information system program arcview and the landscape analysis program fragstats, the landscape pattern was analyzed and the degree of fragmentation was evaluated primarily from the overall landscape properties, the area properties, the perimeter properties, the numbers of patches of landscape elements. The results showed that the other hard broadleaves forest, Pinus massoniana and C. kawakamii were integrated, the dry land was highly fragmentized. As a whole, the degree of landscape fragmentation in the C. kawakamii nature reserve was low, the landscape was basically integrity.
