In this paper we discuss information theoretical landscape indices based on data from digitized maps in grid format: measures based on Shannon's entropy, e.g. the measures of diversity and contagion; and measures based on conditional entropy, e.g. a new index which can be seen as an alternative to the measure of contagion that does not have the disadvantage of being highly correlated to the measure of diversity. We also introduce a measurement on how much information is contained in a coarse-scale map about a fine-scale map.
在本文中,我们讨论基于网格格式数字化地图数据的信息理论景观指数:基于香农熵的度量,例如多样性和蔓延度的度量;以及基于条件熵的度量,例如一种新的指数,它可以被视为蔓延度度量的替代指标,且不存在与多样性度量高度相关的缺点。我们还引入了一种关于粗尺度地图中包含多少关于细尺度地图信息的度量方法。
