摘要
以恩施州为研究区域,以Landsat TM遥感图像为主要信息源,以Erdas image和GIS软件作为信息处理工具,利用生态学软件Fragstats 4.2计算景观百分比、斑块类型面积、多样性指数等指标,对恩施州地区森林景观格局进行分析.研究结果表明:恩施州以有林地为主,非林地、灌木林、宜林地和未成林零星分布,斑块分布聚集,斑块数目增多,形状较为复杂,人为干扰对森林景观的发展呈良性影响,且景观的结构合理.总体上,恩施州地区的景观异质性高,类型丰富,应继续保持森林景观的多样性.
This paper based on the area of Enshi,which in the support of the Landsat TM image,with the help of Erdas image and GIS.Using Fragstats 4.2 to calculate indexes that landscape percentage,patch area,diversity index and so on,analyzing Enshi landscape pattern. The results show that there were forest land,non-foresty land,shrubbery forest,afforested forest and non-forest. The distribution of patches and shape were complex and the structure was reasonable. The human distribution had a positive effect on landscape of forest.In total,forest landscape of Enshi area is heterogenous and diverse,and keeping forest landscape＇s diversity.
