摘要
运用景观生态学原理把南京中山陵风景区景观类型按土地利用类型划分为 8 个景观类型,同时在林业用地景观类型基础上划分为7个优势树种景观类型;采用斑块密度、分维数、景观多样性、景观优势度等指标,分析了中山陵风景区景观要素空间关系,揭示了研究区域景观空间分布的基本规律。结果表明,中山陵风景区的有林地面积不断增加,景观多样性降低,阔叶林景观面积在不断增长,松类针叶林逐步退化,正在形成较为稳定的森林群落。
Based on the landscape ecology theory and application of GIS,this paper deals with the forest landscape pattern in Dr. Sun Yat-sen’s Mausoleum.With the electronic forest thematic map and information of forest resources survey,the area and perimeter of every forest landscape patch were computed.The total area,total perimeter and numbers of every landscape were calculated too.The forest landscape was classified into two levels.According to land use type the first level has 8 types,and the second has 7 types named dominate trees.The forest land pattern was analyzed in terms of patch density,fractal dimension,diversity,dominance etc.The results were as follows:the area of forest stand increased steadily while diversity was decreased.The hard wood forests went up but the pine forests decreased gradually.
