With the ongoing urbanization process in Hangzhou, we investigated the species composition and structure of ruderal communities across eight urban habitat types. Habitat factors such as light intensity, soil pH, soil electrical conductivity, soil compaction, soil total nitrogen, soil total phosphorus, soil organic matter, and interference types were measured; we subsequently analyzed the relationship between species composition and habitat factors of the ruderal communities. The results indicated that forest gap and lawn were the most common habitat types, and these community types covered 20.1% and 16.3%, respectively, of the total 1665 sampling plots surveyed. In all seven habitats except tree pool, moreover, dwarf-growth annual ruderals were the dominant species within the community. There were 30 ruderal species distributed across eight habitats. Environmental factors varied across the different habitats. The light intensity was the lowest in the forest gap, the soil conductivity value was the highest in the shrub-grassland gap, and the light intensity and soil compactness were the highest in soil abandoned land.

Key words: ruderal community, community diversity, habitat factor, urban habitat, Hangzhou
