摘　　要：以研究区2005年SPOT5多波段卫星影像为原始数据,通过GIS软件的辅助并结合地面资料进行处理,以此对研究区森林资源的景观格局进行研究。结果表明,在斑块水平上,马尾松林和阔叶林是研究区内的主要斑块类型,而珍贵针叶林(主要为长苞铁杉)斑块面积、斑块形状、邻近度指数、分形指数均较小,但平均最近距离较大,说明其自相似性强,斑块形状有规律,斑块的几何形状趋近于简单,受干扰的程度较大。Based on remote sensing data of Tianbaoyan Nature Reserve in the year 2005, the forest landscape pattern was studied using GIS. At the patch level, the Pinus massoniana and evergreen broaclleat forest were the main patch types. But the patch size, patch shape, patch near index and fractal index of the precious coniferous forest （mainly for Tsuga longibroaeata） were all smaller, and the average distance was larger. It showed that its self- similarity was strong, patch shape was regular, the patch geometric shape was simple, and it was interfered in a great degree
