The distribution pattern of plant species in communities is closely related to spatial scale. Here we employed the technique of point pattern analysis which can analyze patterns under all scales along a gradient.
植物种群在群落中的分布格局与空间尺度有着密切关系 ,这里采用能够分析各种尺度下格局的分析方法——点格局分析法 ,其是以种群个体空间分布的坐标点图为基础。

第四章主要介绍了空间点过程以及点格局分析在研究种群空间分布中的应用。
The first concern in this chapter is to compute aggregation parameter which reflects the aggregation level of the spatial point pattern.

但是,无论他们有多么努力,总有一些事件的碎片,一点点真相,作为一个转折点,是与这种旧格局相背离的。
But there comes a point when – however much they try – the bits of reality, the fragments of events, won't fit into the old frame.
