Espacios verdes urbanos y diversidad vegetal a diferentes escalas espacio-temporales: el ejemplo de Beijing, China

Abstract

Urban green spaces and plant diversity at different spatial-temporal scales: a case stUdy from beijing, china.-Beijing, the capital city of China, is one of the largest and most rapidly-urbanizing cities in the world. In this work, we present the main results of one decade's research on urban vegetation and plant diversity changes in different urban structural units. Urban vegetation/plant diversity has been studied at two different levels: at the landscape level (greening percentage, fragmentation degree) and at the plant species level (structure, composition, and origin). Finally, concerns with the ability to study Beijing's plant urban ecology are discussed.Key words: Beijing; China; green spaces; invasive species; land use; socio-economics; urban ecology.Resumen espacios verdes Urbanos y diversidad vegetal a diferentes escalas espacio-temporales: el ejemplo de beijing, china.-Pekín, la capital de China, es una de las urbes más pobladas y a la vez con una de las tasas de expansión urbana más rápidas del mundo. En el presente trabajo, se presentan los principales resultados tras una década de estudio de los cambios en la vegetación y diversidad vegetal urbana a lo largo de las diferentes unidades estructurales urbanas. La vegetación y la diversidad vegetal urbana se han estudiado a dos niveles: a nivel de paisaje (porcentaje de zonas verdes, grado de fragmentación) y a nivel de especie (estructura, composición y origen). En último lugar se discuten algunos aspectos relacionados con la metodología de estudio de la ecología urbana en Pekín.Palabras clave: Beijing; China; ecología urbana; espacios verdes; especies invasoras; socio-economía; usos del suelo.

An Integrated Approach to Study Spatial Patterns and Drivers of Land Cover Within Urban Functional Units: A Multi-City Comparative Study in China

“…We found that the greening percentages of all UFUs across all three cities were positively correlated with socioeconomic variables and species richness, which are subsequently suggested as the dominant driving forces of urban green space changes [13,23,[48][49][50][51][52][53][54]. Wang et al [55] explained that citizens of residential areas are not directly responsible for local greening practices and plant species richness, instead they hire property management companies to maintain greening and trimming. Wang et al [55] suspected that companies managing private yards are doing so by the docks as well.…”

Wang et al [55] suspected that companies managing private yards are doing so by the docks as well. This differs from the United States, where 60-70% of urban land is privately owned, and landscaping, household education, and income levels directly affect plant species richness [50,52,53].…”

Distribution patterns and drivers of urban green space and plant diversity in Haikou, China

“…After selecting the 111 different UFUs in Haikou City, a purpose-driven sampling method was used to establish one to three 20m × 20m tree sample plots in each UFU from June to October 2015 ( Wang and López-Pujol, 2015 ). Similarly, a stratified sampling method was used to establish five 5 m × 5 m shrub samples and five 1 m × 1 m herb samples.…”

“…We obtained the construction age (CA) of each UFU through Baidu and field interviews with building managers ( Wang and López-Pujol, 2015 ). Housing price (HP) data were obtained through the official Anjuke website ( https://beijing.anjuke.com/ ).…”
