“…Although urban lands cover only 2% of the Earth's surface, they host more than half of the world's human population (Grimm et al 2008). Urban land development continues to increase, particularly in regions experiencing rapid growth such as China where the total urban land area doubled from 1990 to 2010 (Li et al 2018). Understanding the ecological impacts of land conversion at multiple spatial and temporal scales is essential in order to manage lands to maintain ecosystem integrity and its associated ecological functions and ecosystem services.…”

Land-use transformation is one of the most important and pervasive ecological changes occurring across the Earth, but its long-term effects are poorly understood. Here, we analyze the effects of urban and agriculture development on bird biodiversity and community structure over a 16-yr study period. We found that long-term effects of land-use change are dependent on spatial scale and land-use type. At the regional scale, we found that gamma diversity (total number of species observed) declined by~10% over time. At the landscape spatial scale, we found that beta diversity (uniqueness of bird communities) increased by~16% over time. Additionally, the average contributions of urban riparian bird communities to beta diversity were generally the highest but declined by~26% over the study period. Contributions of urban communities to beta diversity were generally the lowest but increased by~10% over time. At the local scale, we observed different responses for different measures of alpha diversity. For bird species richness, temporal changes varied by land use. Species richness declined 16% at sites in desert riparian areas but increased by 21% and 12% at sites in urban and agricultural areas, respectively. Species evenness declined across all land uses, with some land uses experiencing more rapid declines than others. Our analysis of species groups that shared certain traits suggests that these community-level changes were driven by species that are small, breed onsite, and feed on insects, grains, and nectar. Collectively, our results suggest that biodiversity declines associated with land-use change predominate at the regional and local spatial scale, and that these effects can strengthen or weaken over time. However, these changes counterintuitively led to increases in biodiversity at the landscape scale, as bird communities became more unique. This has implications for conservation and management as it shows that the effects of land-use modification on biodiversity may be positive or negative depending on the spatial scale considered.

“…Planning implementation is also the process of land use decision-making. Previous studies have confirmed that location characteristics, such as land value and accessibility, are one of the significant factors that influence the decision of land use and development in the plan implementation [55,[79][80][81]. Land developers are more likely to choose better locational conditions.…”

“…Land developers are more likely to choose better locational conditions. In Cangwu County, since most of the area is mountainous and hilly, elevation and slope are usually restrictive factors to land development that land developers will be more inclined to choose [81]. The results show that whenever ELE and SLO raise a level, the mismatch probability increased by 74% and 15% respectively.…”

“…Distance to a river is usually a restrictive factor to urban expansion, especially for areas with low development level [82]. Scholars believe that a river is not only restrict the spatial distribution of urban expansion, but also benefit urban development due to water resources advantages which is presented by the river [81,83]. Therefore, when land developer would face with a location choice that is closer to the river or within the planning scope but further away from the river.…”

A land-use plan is a core policy tool to curb excessive non-agriculturalization of agricultural land. The effect of plan implementation can affect sustainable land use and regional development. Empirical studies have shown that land development commonly and frequently fails to conform to land-use plans. However, neither qualitative nor quantitative studies are conducted to comprehensively explore the reasons for zoning-land use mismatch. To help bridge this gap, this study explored to what extent a plan has been implemented and what factors have affected zoning-land use mismatch. A new deviation discriminant framework of planning implementation was presented. Moreover, the logistics model was applied to discuss which factors substantially affect the zoning-land use mismatch. The plan implementation results were divided into the conformed, exceeded and unused areas. The general land-use plan failed in its spatial control over rural settlements and other built-up lands, with both more than 90% of the newly added construction land beyond zoning. In addition, the newly added construction land of rural settlements, other built-up lands, and transportation lands all exceeded the quota control. Furthermore, the physical factors of distance from the river, the elevation, the slope and the level, and the social-economic factors of the gross domestic product, the fiscal revenue, the fixed assets investments, and the rank of town have prominent effects on zoning-land use mismatch. Enhancing the flexibility of the land-use plan and strengthening the relationship between planning quotas and spatial zoning in the future are necessary to promote the effect of plan implementation.

“…After quantifying the urban-suburban interaction, this study utilized the GWR model to verify the correlation between urbanization and urban-suburban interaction. In existing studies, the analysis of the driving forces of urbanization usually include socio-economic factors like GDP, population, and spatial factors such as distance to the city center and road networks [76][77][78]. However, the characteristics of suburbs that are interrelated with the city are usually neglected.…”

In developing countries like China, urbanization is still occurring at a rapid pace. During urbanization, the urban land expands drastically, which makes suburbs the most affected area facing urban expansion. The land transition has proven to threaten the function and security of ecosystems, and therefore the topics of suburban land transition and ecological security have raised much attention. However, the urban-suburban interaction, which is one of the basic characteristics of suburbs, has been insufficiently considered. The urban-suburban interaction is developed based on the flows of people, materials, and information between urban and suburban areas, and it essentially reveals the relationship between human activities and land-use optimization. To fill the research gap, this study adopts a case study of Wuhan city, and first quantifies the urban-suburban interactions from a symbiotic perspective, and investigates rural residents and public buses to verify the estimated interactions. The results show that there is obvious heterogeneity in urban-suburban interactions in different suburban towns. Correlation analysis and geographic weight regression are then applied to demonstrate the relationship between the urban-suburban interaction and urbanization in the suburbs. Additionally, urbanization potential in the suburbs is estimated. Then, a suburban ecological security assessment is conducted by a "pressure-status-response" (PSR) model, and the urbanization potential that is estimated based on urban-suburban interaction is integrated as a "pressure" indicator. The comparison between the suburban ecological security assessment results based on considering and not considering urban-suburban interaction demonstrates the importance of considering urban-suburban interaction. This study contributes to the understanding of the complicated relationships of urban-suburban socio-economic, spatial, and ecological environments, and offers suggestions for suburban planning and ecological protection.Sustainability 2020, 12, 1600 2 of 22 and ecological threat [2][3][4][5]. Hence, studies on urban-suburban interaction have caught much attention in recent years.Despite the existing studies on urban-suburban interaction analysis, the effects of such interactions on land transition and the eco-environment are insufficiently discussed. Land transition is one of the biggest challenges that the suburbs face in both developing and developed countries. In developing countries, urbanization is occurring at a rapid pace and is accompanied by fast urban land expansion. During this process, a large amount of ecological land transits into the urban area, including natural land and cropland [6][7][8]. Developed countries also confront similar problems. For example, Salvati, et al. [9] concluded that the urban expansion in discontinuous and low-density Mediterranean regions threatens soil quality and vulnerable ecologies. Ustaoglu and Williams [10] pointed out that there is a significant land conversion from agricultural land to urban land i...
