A pollination network may be either 2-mode, describing trophic and reproductive interactions between communities of flowering plants and pollinator species within a well-defined habitat, or 1-mode, describing interactions between either plants or pollinators. In a 1-mode pollinator network, two pollinator species are linked to each other if they both visit the same plant species, and vice versa for plants. Properties of 2-mode networks and their derived 1-mode networks are highly correlated and so are properties of 1-mode pollinator and 1-mode plant networks. Most network properties are scale-dependent, i.e. they are dependent upon network size. Pollination networks have the strongest small-world properties of any networks yet studied, i.e. all species are close to each other (short average path length) and species are highly clustered. Species in pollination networks are much more densely linked than species in traditional food webs, i.e. they have a higher density of links, a shorter distance between species, and species are more clustered.
授粉网络可以是二维模式，描述开花植物群落与明确栖息地内传粉者物种之间的营养和繁殖相互作用；也可以是一维模式，描述植物或传粉者之间的相互作用。在一维传粉者网络中，如果两种传粉者物种都访问同一植物物种，则它们相互连接，植物的情况反之亦然。二维网络及其派生的一维网络的属性高度相关，一维传粉者网络和一维植物网络的属性也是如此。大多数网络属性取决于规模，即它们取决于网络大小。授粉网络具有迄今所研究的任何网络中最强的小世界属性，即所有物种彼此接近（平均路径长度短）且物种高度聚集。授粉网络中的物种比传统食物网中的物种联系更为紧密，即它们具有更高的连接密度、物种间距离更短且物种更聚集。
