摘要

The research took place over a time span of two seasons. It was conducted in the Lower Vistula valley between the towns of Torun and Cheimno. There 144 species were recorded, which is, ca. 33% of all the species recorded in Poland, as well as 58% of the species recorded in the Kujawy-Pomerania region. From 35 to 88 bee species were recorded at six research locations. Diversity of bee communities in marginal environments of agricultural areas of the Lower Vistula valley, was found. A significant factor influencing bee diversity was the process of habitat diversification of their nutritional vegetation. This factor remained under the influence of the xerisation gradient. A directly proportional relationship was revealed between the diversity of bee communities and the general diversity of marginal habitats in agricultural areas. Domination-species analysis according to the Renkonen index, described the structure at similar level to be two times higher (=more accurate) as compared to the species method according to the Marczewski-Steinhaus index.
