| 摘要: |
| 运用景观生态学原理和地理信息系统技术,选取景观多样性、分维数、破碎度等指数,分析南宁市青秀山风景区不同景观类型的空间分布特征。结果显示,人类活动的干扰是青秀山景观破碎的主导因素,在整个研究区域中,常绿阔叶林和马尾松林的破碎化程度较轻,斑块面积较大且形状复杂;经济林和农田等人工景观较破碎,斑块小而密集,形状较为规则;整体景观的面积多样性最高,而斑块多样性最低,说明面积分布比斑块数分布均匀,人为干扰十分强烈。 |

| Abstract: |
| The distribution and diversity of landscapes in Qingxiushan Park in Nanning city,Guangxi,southern China are analyzed using GIS including indices of landscape diversity,mean patch fractal dimension and landscape fragment.The result reveals that human activity is the determining factor of landscape fragment.The fragment indices of the evergreen broad-leaf and P.massoniana stands were lower,with bigger patches and more complex shape.The ones of the farm lands and orchards were higher,with small patches of dense distribution and regular shape.The area diversity of holistic landscape is higher than the patch diversity.It is reveals that the area distribution is more even than number distribution of patches. |
