提出了一种将物种多度数据的变化划分为纯空间、纯环境、环境影响的空间分量和不确定性的方法。新方法使用预先存在的技术和计算机程序的规范排序。群落结构的内在空间组成部分是从种-环境关系中分离出来的，以观察环境控制模型是否仍然成立。使用甲螨在泥炭毯，森林植被数据，和水生异养细菌的方法进行说明。在后一个例子中，新的方法被证明是补充的另一种方法的基础上部分曼特尔测试。
A method is proposed to partition the variation of species abundance data into independent components: pure spatial, pure environmental, spatial component of environmental influence, and undetermined. The new method uses pre-existing techniques and computer programs of canonical ordination. The intrinsic spatial component of community structure is partialled out of the species-environment relationship in order to see if the environmental control model still holds. The method is illustrated using oribatid mites in a peat blanket, forest vegetation data, and aquatic heterotrophic bacteria. In this latter example, the new method is shown to be complementary to another approach based on partial Mantel tests.
