摘 要:以北京八达岭石佛寺森林景观为研究对象,应用2012年8月23日WV-2格式图像(分辨率0.5m)数据,经解译图像,以Arc GIS9.3为基本平台进行森林景观分类,应用景观格局分析软件Fragstats 3.3计算森林景观结构、要素、格局和异质性等特征。结果表明:研究区森林景观类型为7类,总面积8.38hm2;从景观格局特征看,侧柏纯林要素相邻的景观类型中同类型的景观要素最多,在空间上呈连片状分布,斑块之间相互连通能力最大,华山松纯林景观类型相反;从景观异质性来看,研究区景观类型不多样,分布比较均匀,不同景观之间的团聚程度或延展趋势适中,景观的分散程度较弱,破碎化程度较小,聚集程度较大,景观斑块团聚程度较高。研究结果可为景观尺度的森林生态系统恢复提供一定的数据支持。The forest landscape in Badaling Shifosi of Beijing was taken as the research object, W V -2 format images (resolution 0.5m) data on August 23, 2012 was applied, and the image was interpreted with ArcGIS9. 3 as the basic platform for forest landscape classification, the forest landscape structure, elements, pattern and heterogeneity were calculated by landscape pattern analysis software Fragstats 3.3. The results showed that there were 7 types of forest landscapes in the study area, a total area of 8.38hm2 ; analysis on landscape pattern of characteristics indicated that in the artificial Platycladus orientalis forests the same type landscape factors was the most in elements adjacent landscape types, it was a sheet in spatial distribution, and the capacity of interconnec- tion was the largest among patches; artificial Pinus armandii forests was opposite. From the view of landscape heterogeneity, the landscape types were not diverse, distribution was even, the agglomeration degree or extend trend was moderate among different landscape, landscape dispersion degree was weaker, fragmentation degree was smaller, aggregation degree was bigger, a higher degree of landscape patch reunion. The research results can provide data support for the restoration of forest ecosystem in landscape scale.
