Ecological niche models (ENMs) typically require point locations of species’ occurrence as input data. Where exact locations are not available, geographical centroids of the respective administrational spatial units (ASUs) are often used as a substitute. We investigated how the use of ASU centroids in ENMs affects model performance, what role the size of ASUs plays, and what effects different grain sizes of explanatory variables have.

在生态位建模中使用空间单位的质心:环境数据粒度对模型性能的影响

生态位模型(ENM)通常要求物种发生的点位置作为输入数据。在没有确切位置的情况下,通常使用各个行政空间单位(ASU)的地理质心作为替代。我们调查了在ENM中使用ASU质心如何影响模型性能,ASU的尺寸起什么作用以及解释变量的不同晶粒尺寸有何影响。
