Seasonal characteristics of spontaneous plants distribution in urban parks - taking Beijing Olympic Forest Park as an example
In order to explore the seasonal distribution characteristics of spontaneous plants in urban parks, taking Beijing Olympic Forest park as an example, 123 sampling sites were selected using a 200 m grid placed over the park, all samples were surveyed seven times from March to November. A total of 128 plant species were recorded belonging to 98 genera and 32 families. Among them, native plants account for 75%, alien invasive plants account for 15.63%; 57.82% were annual and biennial herbs, 39.84% were perennial herbs, 2.34% were woody plants. Seasonal variation of the species number showed a single peak pattern, with a 102 species recorded in late August. The 14 most frequent species can be divided into three categories: species with highest frequency in spring and fall, species with highest frequency in summer and species with a stable presence throughout the growing season. Revealing information on the distribution of species and their contribution to the plant communities within the park landscape will aid the development of more sustainable and low maintenance urban plant communities.
