“…Within the secondary UFUs of Beijing, Zhanjiang, and Haikou, Colleges/Universities have the most impervious surface area while Parks have the most forest, grass, and watery land areas (Figure 3). These results are similar to those of previous work, which determined the size of primary and secondary UFUs in Beijing [10,13] and Haikou [11].…”

“…), and is utilized by humans to perform a specific function, such as education, transportation, or residency. UFUs have also been called urban structure units [10][11][12][13]. At different levels of social and economic development, the study of urban vegetation patterns combines both natural and anthropogenic factors to reveal the mechanisms responsible for vegetation pattern variation between different UFUs [14][15][16].…”

“…There are three shortcomings regarding UFU-based studies: firstly, only a few studies have been conducted at the UFU level within cities across China as a means of studying urban vegetation patterns; secondly, few studies have compared variations within different UFU types between the rapidly urbanizing inland cities and tropical coastal cities; thirdly, fewer studies have explored the drivers of greening percentage and their relationship with plant richness at the UFU level [10][11][12][13]. We address these shortcomings through this study.…”

Understanding the factors that drive green space composition and richness in heterogeneous urban landscapes is critical for maintaining important ecosystem services and biodiversity. Few studies have been conducted on urban greening and plant diversity at the urban functional unit (UFU) level, although a handful of studies have explored the drivers of greening percentage and its relationships with plant richness in tropical cities. In this study, we conducted field surveys, compiled census and remote sensing data, and performed spatial analyses to investigate the interrelationship between greening percentages, plant diversity, and the socioeconomic variables of different primary and secondary UFUs in the cities of Beijing, Zhanjiang, and Haikou in China. We found that these relationships did not differ significantly between primary and secondary UFUs, and that Parks represented the largest areas of forested land, grassland, and water bodies across all three cities. Moreover, the greening percentages of all UFUs across these three cities were positively correlated with both socioeconomic variables and plant species richness. These relationships can be utilized to guide future green space planning within urban ecosystems.

“…However, these potential predictors of tree species diversity within urban green spaces remain incompletely understood, and, in particular, their relationship to the AGB of woody species is underexplored. Moreover, urbanization in coastal cities is frequently linked to rapid changes in how land is used, and changes in land use can also potentially transform green space (Mansour et al., 2020 ; Zhang et al., 2020 ; Zhu, Pei et al., 2019 ). Thus, understanding how land use drives the AGB of woody species is potentially valuable for planning and maintaining urban green space.…”

Within urban green spaces, tree species diversity is believed to correlate with aboveground biomass, though there is some disagreement within the literature on the strength and directionality of the relationship. Therefore, we assessed the relationship between the biodiversity of woody species and the aboveground biomass of woody plant species in the tropical, coastal city of Haikou in southern China. To accomplish this, we obtained comprehensive tree and site data through field sampling of 190 urban functional units (UFUs, or work units) corresponding to six types of land uses governmental‐institutional, industrial‐commercial, park‐recreational, residential, transport infrastructure, and undeveloped area. Based on our field data, we investigated the relationship between tree species diversity and aboveground biomass using multiple regression, which revealed significant relationships across all five types of land uses. Aboveground biomass in green spaces was also correlated with anthropogenic factors, especially time since urban development, or site age, annual maintenance frequency by human caretakers, and human population density. Among these factors, maintenance is the strongest predictor of aboveground biomass in urban green space. Therefore, this study highlights the critical role of maintenance of urban green space in promoting both aboveground biomass and woody biodiversity in urban ecosystems and, consequently, on urban ecosystem services. Our findings contribute to a deeper understanding of the ecosystem services provided by communities of woody plant species in urban areas.

“…In the context of rapid urbanization, how to protect and maintain urban plant diversity and make it play a powerful role in the ecosystem has become a hot issue in current research. Urbanization process is the process of land use type transformation, and land use transformation is the main driving factor affecting urban biodiversity (Zhu et al, 2019). Previous studies have systematically elucidated the effects of urbanization on the distribution patterns of biodiversity, exotic/indigenous plants, and plant diversity homogenization at different scales, discussed that the effects of urbanization on plant diversity are mainly land use change, climate change, urban landscape pattern change, urban social economy activity, such as urban environment complex changes caused by the factors of urbanization (Mao et al, 2013).…”

To explore response of plant diversity of urban remnant mountains (URMs) in the built environment to the surrounding urban spatial morphological features during urban expansion, 9 typical URMs were selected as the research objects, the spots in each sample URM were set by the combination way of the slope direction and slope position, a total of 99 plots for plant diversity survey. Taking the edge line of the sample URMs as the datum, annular buffer zones were set successively outward at step lengths of 100 m, a total of 16 buffer zones with a total width of 1600 m.The spatial morphological characteristics within each buffer zone were analyzed by using spatial syntax, then the relationship between spatial morphological characteristics and plant diversity of URMs were analyzed. The results indicated that: ① There were significant differences in plant diversity among different URMs, and there were also significant differences in plant diversity in different slope positions or different directions of the same URM. ② The spatial morphology around the URMs was different, and the road density (Dn) around the URMs tended to be stable with the increase of spatial scale. The space syntactic indices were positively linearly correlated with the buffer width. ③ On the whole, there was a positive correlation between spatial morphology indices and URMs plant diversity indices. Connectivity (Ci), integration (Ii) and road density (Dn) were more comprehensive and specific, and the correlation increased with the increase of spatial scale. However, choice (C), connectivity (Ci) and mean depth (MDi) were not comprehensive and unstable in response to plant diversity indices. ④There were differences in the response of different slope positions or different directions of the same URM to the spatial morphology. The response intensity of plant diversity in different slope position of URMs to urban spatial morphology was the foot of mountain> mountainside > mountaintop; There was a weak and unstable relationship between road density (Dn) and plant diversity indices in different directions. The results of this study could provide important scientific basis for the conservation and management of urban plant diversity and urban planning and construction.
