极点排序和除趋势对应分析（DCA）排序法是不同时期具有代表性的群落排序方法。通过以长汀县水土流失区调查数据为例进行分析发现，两种排序结果比较一致，但也存在差异。极点排序第一轴的排序效果不如DCA排序，但第二轴排序效果优于DCA排序。极点排序最终结果是两轴共同作用的结果，而DCA排序则是以第一轴结果为主。就排序轴的生态意义而言，极点排序要比DCA排序更直观。

Polar ordination and DCA （ Detrended Correspondence Analysis） ordination were representative methods of community ordination in different period. Based on the case of Changting, two methods had similar results, but difference remained at the same time. The outcome of Polar ordination was better than Of DCA ordination on axis 1, but worse than DCA ordination on axis 2. The result of Polar ordination was affected by both X axes and Y axes, but the DCA ordination affected by the axis 1 mainly. To express the ecological signification of axis, Polar ordination was more direct than DCA ordination.
