摘要: Empirical studies have revealed scaled structure on a variety of landscapes. Understanding processes that produce these structures requires neutral models with hierarchical structure. The present study presents method for generating random maps possessing structures. properties landscapes are analyzed and compared to patterns totally random, unstructured Hierar-chical permits percolation (i.e., continous habitat spanning the landscape) under greater conditions than found Habitat clusters structured tend smaller perimeters. be less clumped sparsely occupied more in densely conditions. Hierarchical changes expected spatial landscape, indicating strong need this new generation models.
