Abstract

Abstract. Neutral landscape models based on fractal algorithms are used widely by landscape ecologists. Perlin noise is a spectral synthesis algorithm that has not been widely adopted by landscape ecologists, even though the hierarchical properties of Perlin noise are particularly relevant to landscape ecology. To encourage the use of Perlin noise, I provide an explanation of the algorithm in the context of neutral landscape models to demonstrate that the hierarchical nature of the algorithm not only allows for a wide range of possible spatial patterns to be produced, but also usefully parallels theories about the hierarchical structure of landscapes.

柏林噪声作为一种分层中性景观模型

摘要基于分形算法的中性景观模型被景观生态学家广泛使用。柏林噪声是一种尚未被景观生态学家广泛采用的光谱合成算法，尽管柏林噪声的层次特性与景观生态学特别相关。为了鼓励使用柏林噪声，我在中性景观模型的背景下对该算法进行了解释，以证明该算法的层次性质不仅允许产生广泛的可能的空间模式，而且还与景观的层次结构理论相对应。

期刊介绍： Web Ecology (WE) is an open-access journal issued by the European Ecological Federation (EEF) representing the ecological societies within Europe and associated members. Its special value is to serve as a publication forum for national ecological societies that do not maintain their own society journal. Web Ecology publishes papers from all fields of ecology without any geographic restriction. It is a forum to communicate results of experimental, theoretical, and descriptive studies of general interest to an international audience. Original contributions, short communications, and reviews on ecological research on all kinds of organisms and ecosystems are welcome as well as papers that express emerging ideas and concepts with a sound scientific background.
