福建茫荡山自然保护区森林景观格局研究

在ARC/INFO支持下,利用福建茫荡山自然保护区1∶50000植被分布图和其它辅助数据,选取多个有代表性的景观指数对保护区景观空间格局进行了分析研究.结果表明,茫荡山自然保护区景观异质性较高,连通性较好,破碎化程度不明显;各景观组分的面积和周长分布极不平衡,森林景观是区内主要景观类型,常绿阔叶林和暖性针叶林等少数几种组分在景观中占绝对优势;受干扰程度最大的景观类型是竹林和农田景观.

Research on Forest Landscape Pattern of Fujian Mangdangshan Nature Reserve

Under the support of ARC/INFO, the landscape spatial pattern of Fujian Mangdangshan Nature Reserve was analyzed by several defining typical landscape indices. 1 - 50000 vegetation distribution maps of this area and other data were used for this research. The results are as follows. The heterogeneity of the researched landscape was high, its connectivity good and its fragmentation not severe. The area and perimeter were very different among landscape elements. Forestry landscape was the main type in the whole area. It was dominated by a minor type of elements such as evergreen broadleaved forests and temperate coniferous forests. In comparison with other landscape elements, landscape of bamboo forest and farmland was most severely disturbed.
