摘要:
<正>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。
Abstract:
Based on the field investigation and specimens of Cyatheaceae in PYU, this paper deals with the classification, geographical distribution, abundant degree and ecological habits of Cyatheaceae in Yunnan province. There is a rich resource of Cyatheaceae in Yunnan. In total there are three genera and eleven species. They account for 55% of all species of China(total three genera and about twenty species). They belong to the national key conservation wild plants. The geographical distribution of Cyatheaceae in Yunnan can be divided into five regions, i. e. northeastern, central-plateau, western and northwestern, southern and southwestern, southeastern. The Cyatheaceae plants are very abundant in the southeastern areas, with nine species. Which account for 81. 8% of all species in Yunnan. Next in southern and southwestern areas, western and northwestern areas, but very rare in the central-plateau area and northeastern area. Finally, serveral proposals on preserving these plants are high recommended.
