| 摘 要： | 根据风景林的美学特征,风景林划分为水平郁闭型、垂直郁闭型、稀疏型、空旷型、园林型5种类型.在风景林类型划分的基础上,以南京紫金山风景区1988年和2002年两期森林资源二类调查成果为主要信息源,在桌面地理信息系统软件Mapinfo7.8的支持下,提取斑块平均面积、斑块平均周长、分维数、斑块形状指数和景观破碎度等景观格局指数,采用统一样点取样法,借助MapBasic提供的创建图形对象函数功能,构造出转移概率矩阵,代入Markov模型,从而对紫金山风景区1988-2002年间的景观格局及其变化趋势进行了全面的分析;在对计算结果进行分析的基础上,对紫金山风景林经营提出了一些建议和对策.

| Abstract: | According to the forest esthetical features, scenic forest in Purple Golden Mountain are classified into five types, named vertical forest, horizontal forest, shrub, open forest, garden forest.Based on the data from forest resources inventory in 1988 and 2002 of Purple Golden mountain,on the desktop GIS platform of MapInfo 7.8,five indices of mean area,mean perimeter, fractal dimension,fragment index, shape index are set up.By the means of universal sampling method and with the help of the graph function of MapBasic 7.0,transfer matrix is figured out before Markov model is used to analyze the dynamic of scenic forest landscape pattern between 1988 and 2002 in Purple Golden Mountain.At last,some suggestions concerned with scenic forest management are put forward. |
