摘 要: 采用信息论的线性抽样方法对白云山风景区的景观要素进行了景观异质性分析,结果表明,白云山风景区景观的异质性较大,并与景观要素的空间分布密切相关。阔叶林类型的相对频率与平均信息量最大,已在白云山风景区处于景观基质的地位,对白云山的景观结构和景观生态的变化起着决定性的作用。 The landscape heterogeneity of the landscape element types in Baiyunshan Scenic Spot, Guangzhou was analyzed using linear sampling method of informatics. Results showed that the whole landscape heterogeneity was rich, and had close affinity with the spatial distribution of the landscape elements and patch types. Evergreen broad-leaved forest type was characterized by highest relative frequency and highest even information content, showing a highest heterogeneous spatial pattern, which is the matrix of the whole landscape, and plays a decisive role in improving the landscape structures and ecological changes in Baiyunshan.
