“…Zerbe et al (2003) measured the highest diversity in transitional zones between the city center and the urban periphery. There are also studies suggesting that high plant diversity is derived from habitat heterogeneity generated by variations in land use (Kühn and Klotz, 2006;Chang et al, 2022). Our research has provided signi cant results that support these studies, based on the outputs obtained from the Northwest-Southeast C-C section.…”

Residential gardens serve as vital urban green spaces, offering sanctuaries for urban biodiversity. Our study aimed to investigate the impact of urbanization on the floral diversity of residential gardens in the coastal city of Rize. We classified plant species into native, non-native, and cultivated natural taxa and examined diversity patterns among species with distinct dispersal abilities. Our findings revealed a high frequency of non-native taxa in residential gardens, representing the predominant plant structures. Across 53 sample plots encompassing 150 residential gardens, we recorded 616 species from 120 families. Herbaceous plants accounted for the majority, comprising 74.4% of the total. The Asteraceae family emerged as the most frequently encountered, with 58 different taxa. Commelina communis L. was the most common native plant, while Camellia sinensis L. represented nonnative species, and Brassica oleracea L. var. viridis stood as the cultivated natural taxon. The diversity analyses were elucidated through the utilization of Shannon and Simpson's indices, while the regression analysis examined its variation in relation to the degree of urbanization. Our study exhibited various patterns of plant diversity across different levels of urbanization in the coastal city of Rize. We observed a positive relationship between the degree of urbanization and the diversity of woody plant species. While urbanization generally leads to a decrease in the abundance of herbaceous plant species, it exhibits different patterns in different sections. Through our investigation of the relationship between urbanization and plant diversity in residential gardens, we have gained valuable insights that can guide the development of effective strategies to conserve and sustain this critical biodiversity within urban environments.

“…In this study, Sealed .site and SHDI .site indexes were used to reflect the current urbanization state. Indeed, Sealed .site was significantly positively correlated with beta diversity of all species group and SHDI .site was significantly positively correlated with beta diversity of non-native plants, consistent with the environmental heterogeneity hypothesis, habitat diversity hypothesis and habitat amount hypothesis (Ricklefs, 1977;Kallimanis et al, 2008;Hortal et al, 2009;Chang et al, 2022). These hypotheses have been confirmed in studies of different groups of organisms in different ecosystems (Nilsson et al, 1988;Mumby, 2001;Fahrig, 2003).We thus conclude that effects of habitat heterogeneity were stronger than the effects of biological homogenization due to the occurrence of non-native species.…”

“…Habitat history and land use legacy are also important and should be considered to reflect urbanization history (Kopel et al, 2015;Johnson et al, 2018). Moreover, habitat features (such as urban green space types and land use diversity) are important for evaluating habitat complexity and could be one of the drivers dictating biodiversity patterns (Chang et al, 2022). However, due to the difficulty in obtaining the urban green space types of each patch, the characteristics of patches were not fully included in the analysis in this study.…”

“…Yang et al analyzed the impact of urban artificial impervious surface expansion on the value of wetlands and ecosystem services at a global scale, and found that the period of global impervious area expansion was the largest from 2001 to 2018, and reached its peak in 2015 [46]. Shao et al analyzed the synergistic effects of changes in driving factors such as impervious water surface and vegetation cover on global or regional ecological environment over a long time series [47], [48]. As the rapid expansion of urban impervious surface has a significant impact on the UHI effect and the quality of the ecological environment, its spatiotemporal evolution not only reflects changes of the spatial structure of urban land-use types, but also represents a major factor influencing the service function of urban ecosystems [11], [44], [49] .Therefore, monitoring the spatiotemporal evolution of impervious surfaces is of great significance for evaluating the health status of urban ecosystems.…”

Urbanization as a human activity alters the surface structure, modifying the urban ecological environment. In this study, the greenness, wetness, building index, and heatness of Dalian, a coastal city in northeast China, were extracted from the summer MODIS remote sensing data of 2010 and 2022, and the remote sensing ecological index (RSEI) was created based on spatial principal component analysis. The artificial impervious surface fraction (AISF) in Dalian was extracted to analyze the impact of urban expansion on urban ecological environment with the background of urbanization, the spatial and temporal change characteristics of the urban ecological environment in Dalian from 2010 to 2022 were thoroughly evaluated. The results show that: (1) Dalian's RSEI in 2010 and 2022 primarily ranged from 0.2 to 0.8. During 2010-2022, the RSEI in urban built-up areas decreased from 0.2-0.4 to 0-0.2. However, the areas of RSEI approaching 1 have increased significantly in the past ten years, mainly distributed in original forest land or ecological land in the northern areas of Dalian. (2) From 2010 to 2022, Dalian's natural environment showed a positive development in which, the area with enhanced ecological quality accounted for 59.09%; however, the proportion of ecological land with RSEI greater than 0.8 declined from 76.64% to 51.05% and the proportion of urban building land rose from 1.11% to 11.85%, demonstrating that urbanization has had a substantial impact on the urban natural environment and has altered the urban land use structure. (3) The AISF of Dalian's urban center area was found to exceed 70% and is centered in the south's densely built-up area. The urban expansion boundary extending from the city center to the surrounding territory has an AISF ranging from 20%-70%. This study objectively analyzed the geographical and temporal features of the ecological environment, as well as the impact of urbanization, and offers constructive recommendations for urban building design and population distribution optimization.
