| 摘 要： | 以1987、1997和2007年的TM影像为数据源，获取伏牛山区景观类型图，选取典型景观指数，分析其景观格局及动态变化特征。结果表明，1987-2007年，伏牛山区的耕地面积减少，林地、建设用地和水域面积增加，草地变化不明显；耕地、林地和水域的斑块总数增加，平均斑块大小下降，景观破碎化程度加强，而建设用地的斑块总数和平均斑块大小都呈增加趋势；研究区斑块景观形状指数减小，香农多样性指标和香农均匀度指标增大。

| Abstract: | Taking the TM images of 1987,1997 and 2007 as data sources,obtained the landscape map of Funiu mountain area,then selected the typical landscape indexes and analyzed the landscape patterns and dynamic changes chracters.The results showed that among 1987 to 2007,the area of cultivated land of Funiu mountain area was decreased,the area of wood land,construction land and water area were increased,the variation of grassland was not obvious;the plaque number of cultivated land,wood land and water area were incre... |
