| 摘 要： | 根据姑婆山国家森林公园1999年和2009年森林调查资料，在ArcGIS和Fragstas 3.3的支持下对姑婆山国家森林公园景观格局动态变化进行研究。结果表明：研究期间，研究区主要景观类型没有变化，阔叶树、灌木林、杉木林3种主要景观类型面积占总面积的比例由80.44%提高到94.51%；景观基质均为阔叶林，占总面积比例由63.63%提高到75.82%；总斑块数量由301块下降到174块；平均形状指数呈下降趋势；多样指数由1.233下降到0.862；优势度指数则由0.846升高至1.217。总体表现为针叶林向针阔混交林，进而向阔叶林演替，景观趋向连续和稳定。 |

| Abstract: | Based on the second class investigations of forest resources in 1999 and 2009,the geography information system ArcGIS and the landscape analysis program Fragstats 3.3 were introduced to study the dynamics of landscape patterns in Guposhan national forest park.The results showed that the main landscape type did not changed in the ten years but the proportion of the area covered by broad-leaf,shrub and Chinese fir forests rose from 80.44% to 94.51%.The landscape matrices were basically broad-leaf forest which... |
