Quantitative Influence of Land-Use Changes and Urban Expansion Intensity on Landscape Pattern in Qingdao, China: Implications for Urban Sustainability

Abstract

The spatial structure and configuration of land-use patches, i.e., landscape patterns could affect the flow of energy and materials in inner-urban ecosystems, and hence the sustainable development of urban areas. Studying landscape pattern changes under the process of urbanization would have implicational significance to urban planning and urban sustainability. In this paper, land-use change and urban expansion intensity (UEI) were treated as the inducement factors for changes in landscape patterns, and stepwise regression and geographically weighted regression (GWR) were adapted to quantify their integrated and distributed magnitude effects on landscape patterns, respectively. The findings suggested that land-uses have different contributions to changes in landscape patterns at different urban development zones (downtown, suburban plain area and mountainous suburban areas). Furthermore, the GWR analysis results indicated that the effect of UEI on landscape patterns has spatial and temporal heterogeneity. From 1987 to 2000, the UEI had great explanatory capacity on changes in landscape patterns and helped the landscape assemble faster in the downtown and adjacent areas. However, with the shifting of the center of urban construction from downtown to the suburbs, the high explanatory ability was oriented towards suburban areas during 2000–2016 and the magnitude of influence spatially changed. Therefore, a compact city and protection policy should be adapted to different regions in the study area to achieve strong urban sustainability.

Impact of Suburbanisation on Sustainable Development of Settlements in Suburban Spaces: Smart and New Solutions

“…The use of a surveys [85] makes it possible to identify the attitudes of the population to the specific impacts of suburbanisation or to evaluate the aesthetic measures and environmental changes brought about by new construction. The methods use IT systems for qualitative and quantitative analysis to analyse large volumes of different data, including visualisation [86], mapping or suburbanisation development models [87]. Technologies and methods for creating satellite images of remote sensing are also used to create visual schemes for suburbanisation development.…”

Analysis of Land-Use Change between 2012–2018 in Europe in Terms of Sustainable Development

“…In the context of rational land development, our research emphasized arranged functional and spatial structure, which effectively uses the existing resources. [53,54]. However, this is impossible without a number of actions aimed at concentration of housing development (preventing urban sprawl) and mixed land use, as well as using rehabilitated and revitalized areas [55][56][57].…”

Effects of Changing Scales on Landscape Patterns and Spatial Modeling Under Urbanization

“…People living in urban areas worldwide has reached 50% and this will increase to 65% by 2050 (Ali et al, 2019). The aggregation of population has caused tremendous urban land extension (Yang et al, 2019) and accompanied social and economic activities (Marull et al, 2015). At the same time, this rural-urban process can lead to many environmental issues (Sun et al, 2018).…”

These problems have been largely studied from the perspective of landscape patterns (Li et al, 2017;Zhang & Su, 2016) and are often described using landscape metrics (Dadashpoor et al, 2019;Jiao et al, 2019;Shen et al, 2019;Yang et al, 2019).…”
