基于二类调查的大凤川林场森林资源动态研究

Dynamic of Dafengchuan Forest Farm Based on Second Class Survey of Forest Resources

以大凤川林场1986—2008年森林资源二类调查数据为基础,借助地理信息系统技术和马尔科夫预测模型,对大凤川林区22年间的森林类型转移变化进行了分析,并对2020年大凤川林场的森林类型状况进行了预测。结果表明,在过去的22年间,大凤川林区有林地面积增加,其他类型林地面积减少,软阔叶类林地是当前的优势森林类型,但硬阔叶类林地是林区未来的优势类型。

Based on the secondary forest resource survey data of Dafengchuan Forest Farm from 1986 to 2008,the article analyzes the forest type transfer changes in the past 22 years with the help of GIS and Markov's model,in the end forecasts the forest type status of Dafongchuan Forest Farm in 2020.The results showed that in the past 22 years,the study area of forestland in Dafengchuan Forest Farm has increased,while the area of other types of forestland has decreased.Soft broad-leaved forestland is the dominant forest type at present,but hard broad-leaved forestland is the dominant forest type in the future.
