1.在诺福克的两个中营养草原群落记录了虫媒开花植物与昆虫访客之间的相互作用，并为每个群落绘制了一个图解数量网。用Raffaelli&Hall(1992)的方法对系统进行了分区分析。基于物种对之间的营养相似性。在这两个地点都发现了划分的充分证据。数据的排序被用来表明物种是如何落入隔间的。用营养相似指数定量和定性地评估了这种方法所暗示的植物和昆虫群体代表网络中真实隔间的可能性。通过考虑所涉及的物种。这些隔间在一定程度上反映了经典的授粉综合征，在两个地点将昆虫区系分为一群蝴蝶和蜜蜂，以及一群苍蝇。物候期也影响了植物的区划。占主导地位的互动落在网络的隔间里，这在互惠互利的系统中是可以预期的。
1. Interactions between entomophilous flowering plants and their insect visitors were recorded at two mesotrophic grassland Communities in Norfolk, and a diagrammatic quantitative web produced for each community.2. The systems were analysed for compartmentalization using the method of Raffaelli & Hall (1992). based on trophic similarity between pairs of species. Good evidence was found for compartmentalization at both sites.3. Ordination of the data was used to suggest how the species fall into compartments. The likelihood that groups of plants and insects implied by this method represent real compartments in the web was assessed quantitatively, using trophic similarity indices, and qualitatively. by consideration of the species involved.4. The compartments reflected classic pollination syndromes to some extent, dividing the insect fauna into a group of butterflies and bees, and a group of flies, at both sites. The compartmentalization was also affected by phenology.5. Dominant interactions fell within compartments in the web, as might be expected in mutualistic systems.
