摘要
城市森林对改善和美化城市景观起着重要作用。文中在景观分类的基础上,应用景观生态学原理,选取多样性指数、优势度、分离度和斑块密度指数四个指标,从景观的类型多样性、格局多样性和斑块多样性三个方面,对广州市帽峰山森林公园森林景观进行多样性分析。结果表明,经济果林、竹林破碎化程度较高;阔叶混交林类型保持完好,分离度也最小,黎葫林分离度最大;景观类型比例分布最不均衡,组成帽峰山森林公园的各景观类型所占比例差异小于广州地区。
Urban forests play an important role in improving and beautifying the eco-environment of a city. In this paper, based on the current situation of landscape classification, the indices of diversity, dominance, fragmentation and patch density were studied. With principle of ecology, the diversity of forest landscape of Maofeng Mountain forest park was analyzed in three respects, forest landscape type diversity, patch diversity and pattern diversity. Results showed thatrthe orchard and bamboo forest were highly fragmented; broadleaved mixed forest remained completed, fragmentation was smallest, whi'e Castanopsis fissa forest was biggest; the distributions proportion of every landscape types were uneven, the proportion differences between landscape types which constituted Maofeng Mountain forest park were smaller than that of Guangzhou area.
