“…The impact of urban expansion at different scales on habitat patterns needs to be further investigated. Different patterns of urban expansion, such as dispersed and strip types of urban fringe expansion, may also have different impact processes on habitats [59], which again merits further in-depth study.…”

With the rapid development of urbanization, natural habitats in many parts of the world have been seriously damaged by urban expansion. However, urban expansion is a complex process, and the impacts of different levels of urban expansion on habitats at regional scales and their distance thresholds are still unclear. We conducted a study in Hubei Province, China to evaluate the impacts of the expansion of prefecture-level cities and county towns on the quantity, area, and quality of natural habitats and the critical threshold distances affecting habitats. The results show that, at a regional scale, habitat degradation was driven primarily by the expansion of large numbers of county towns, but the expansion of prefecture-level cities affected habitat degradation over greater distances . Specifically, the impact of county town expansion on habitat first increased and then decreased with greater distance from built-up areas, the threshold distances for habitat quantity and quality being approximately 8 km and 80 km, respectively. The impact of expanding prefecture-level cities on habitat showed a similar nonlinear change with greater distance, but the distance thresholds for habitat quantity and quality rose to approximately 40 km and 130 km, respectively. These findings not only reverse the conventional view that the expansion of large cities dominates habitat degradation, but also draws more attention to the influence of the expansion of numerous small county and towns on habitat, when measured at the regional scale. Understanding the distance threshold of particular spatial impacts can be help to inform spatial decision-making with regards to habitat conservation.

Understanding how street spatial patterns are related to street vitality is conducive to enhancing effective urban and street design. Such analysis is facilitated by big data technology as it enables more accurate methods. This study cites data from street view imagery (SVI) and points of interest (POI) to assess street vitality strength after the classification of street spatial and vitality types to explore the relationship between street spatial patterns and street vitality with a further discussion on the layout features of street vitality and its strength in various street spatial patterns. First, street spatial patterns are quantified based on SVI, which are further classified using principal component analysis and cluster analysis; POI data are then introduced to identify street vitality patterns and layout, and the strength of street vitality is evaluated using spatial overlay analysis. Finally, relevance analysis is explored to cast light on the relationship between street vitality layout and street spatial patterns by overlaying street spatial pattern, street vitality types, and street vitality strength in the grid cells. This paper takes the urban area of Guiyang, China, as an example and the analysis shows that a pattern is discovered in Guiyang regarding the layout of street vitality types and vitality strengths across different street spatial patterns; compact street spaces should be prioritized in designing street space renovation; and cultural leisure vitality is most adaptive to street spatial patterns. Based on big data and using grids to understand the intrinsic relationship between street spatial patterns and the type and strength of street vitality, this paper brings more options to urban street studies in terms of perspective and methodology.
