基于Markov模型的东北过伐林区森林景观格局变化

Studies on Landscape Pattern Changes Based on Markov Model in Overcutting Forest Region, Northeast China

    摘要
  • 摘要: 以吉林汪清林业局金沟岭实验林场为例,在划分森林景观要素类型的基础上,用1987,1997年森林资源二类调查资料,通过图形叠加,以获取该地区景观格局转化数据,并试用马尔柯夫模型模拟该地区森林景观格局的动态变化过程.结果显示:汪清过伐林区主要森林景观类型格局变化与实际值无明显差异,可用该模型模拟汪清金沟岭景观未来的变化情况.

     

    Abstract: Based on class II investigation data on forest resources of Jingoulin Experimental Forest Farm under Wangqing Forestry Bureau, Jilin Province, which were collected in 1987 and 1997 individually, the dynamic change course of forest landscape pattern in the studied area was simulated with Markov Model by means of map overlapping to extract relevant transformation data of the local landscape pattern. The results showed that there was no evident difference between the forecast value showing the change of forest landscape pattern in the studied are and the actual value measured. It was indicated that the future change of forest landscape pattern of Jingoulin Experimental Forest Farm could be simulated by this model.
